As the interest in heirloom cultivars of apple trees, their fruit, and processed products is growing worldwide, studies of the qualitative and quantitative composition of biological compounds are important for the evaluation of the quality and nutritional properties of the apples. Studies on the variations in the chemical composition of phenolic compounds characterized by a versatile biological effect are important when researching the genetic heritage of the heirloom cultivars in order to increase the cultivation of such cultivars in orchards. A variation in the qualitative and quantitative composition of phenolic compounds was found in apple samples of cultivars included in the Lithuanian collection of genetic resources. By the high-performance liquid chromatography (HPLC) method flavan-3-ols (procyanidin B1, procyanidin B2, procyanidin C2, (+)-catechin and (−)-epicatechin), flavonols (rutin, hyperoside, quercitrin, isoquercitrin, reynoutrin and avicularin), chlorogenic acids and phloridzin were identified and quantified in fruit samples of heirloom apple cultivars grown in Lithuania. The highest sum of the identified phenolic compounds (3.82 ± 0.53 mg/g) was found in apple fruit samples of the ‘Koštelė’ cultivar

The aim of this study was to determine the composition and content of phenolic compounds in ethanol extracts of eight different cultivars of American cranberry (Vaccinium macrocarpon Aiton) fruit using spectrophotometric and UPLC-ESI-MS/MS analysis and to evaluate the antioxidant activity in vitro of these extracts. The highest total amount of phenolic compounds evaluated via Folin–Ciocalteu spectrophotometry was detected in American cranberry fruit samples of the ‘Bain’ clone, and the highest total amount of flavonoids was found in samples of the ‘Drever’ and ‘Baiwfay’ cultivars. The highest total amount of the individual phenolic compounds (519.53 ± 25.12 mg/g DW) identified and quantitatively evaluated via chromatography was detected in samples of the ‘Searles’ cranberry cultivar. In the studied cranberry samples, the predominant phenolic compounds were hyperoside, quercetin, and procyanidin A2, while the amounts of other compounds were significantly lower. HCA and PCA revealed that ‘Woolman’, ‘Holliston’, ‘Pilgrim, and ‘Searles’ fruit samples had different quantitative content of phenolic compounds from other cranberry cultivars. Meanwhile, fruit of ‘Baiwfay’, ‘Drever’, ‘Bain’, and ‘Bergman’ were similar in their phytochemical profile.

Phenolic compounds in the fruit of American cranberry (Vaccinium macrocarpon Aiton) determine the antioxidant, anti-inflammatory, anticancer, and other biological effects. The berries are used in the production of medicinal preparations and food supplements, which highlights the importance of qualitative and quantitative analysis of phenolic compounds in cranberry fruit raw material. The aim of our study was to develop and validate an efficient, cost-effective, reproducible, and fast UPLC-DAD methodology for the evaluation of the qualitative and quantitative composition of phenolic compounds in raw material and preparations of American cranberry fruit. During the development of the methodology, chlorogenic acid and the following flavonols were identified in cranberry fruit samples: myricetin-3-galactoside, quercetin-3-galactoside, quercetin-3-glucoside, quercetin-3-α-L-arabinopyranoside, quercetin-3-α-L-arabinofuranoside, quercetin-3-rhamnoside, myricetin, and quercetin. The developed and optimized UPLC-DAD methodology was validated according to the guidelines of the International Council for Harmonization (ICH), evaluating the following parameters: range, specificity, linearity (R2 > 0.999), precision (%RSD < 2%), LOD (0.38–1.01 µg/mL), LOQ (0.54–3.06 µg/mL), and recovery (80–110%). The developed methodology was applied to evaluate the qualitative and quantitative composition of phenolic compounds in fruit samples of cranberry cultivars ‘Baifay’, ‘Bergman’, ‘Prolific’, and ‘Searles’, as well as ‘Bain-MC’ and ‘BL-12′ clones. In the tested samples, the majority (about 70%) of the identified flavonols were quercetin derivatives. The greatest amount of quercetin-3-galactoside (1035.35 ± 4.26 µg/g DW) was found in fruit samples of the ‘Searles’ cultivar, and the greatest amount of myricetin-3-galactoside (940.06 ± 24.91 µg/g DW) was detected in fruit samples of the ‘Woolman’ cultivar.

We investigated the qualitative and quantitative composition of phenolic compounds in the fruit of Rosa L. cultivars grown in Lithuania. The highest total content of phenolic compounds (50.13 ± 4.17 mg GAE/g, p < 0.05) was determined in fruit samples of Rosa pimpinellifolia L. cultivar “Single Cherry”. The highest levels of hydroxycinnamic acid derivatives were determined in fruit samples of Rosa rugosa Thunb. cultivars “Dart’s Defender” and “Adam Chodun”. The highest flavonoid content was determined in fruit samples of Rosa multiflora Thunb. cultivar “Nana” and R. multiflora species. The strongest antioxidant activity evaluated by applying DPPH and FRAP assays was determined in fruit extracts of R. pimpinellifolia cultivar “Single Cherry” and R. rugosa cultivar “Adam Chodun”. Qualitative and quantitative analysis of phenolic compounds in Rosa L. fruit was performed by applying UHPLC. The following phenolic compounds were identified in fruit samples: caffeic acid, chlorogenic acid, quercetin, quercitrin, (+)-catechin, (−)-epicatechin, (−)-epicatechin gallate, rutin, phloridzin, and kaempferol-3-O-glycoside. A strong correlation was determined between the total amount of phenolic compounds determined in extracts of the fruit samples of Rosa L. cultivars and the radical scavenging and reducing activity of their extracts in vitro (R = 0.767 and 0.727, respectively, p < 0.05).

Our research aim was to investigate the quantitative composition of neochlorogenic acid, chlorogenic acid, rutin, hyperoside and isoquercitrin in leaves and fruit of introduced rowan plants to Lithuania using a HPLC method. In leaf and fruit samples, quantitative estimation of neochlorogenic acid (in leaf samples 1.11–11.49 mg/g, in fruit samples 0.93–5.43 mg/g), chlorogenic acid (in leaf samples 2.74–21.91 mg/g, in fruit samples 0.55–7.50 mg/g), rutin (in leaf samples 0.03–4.88 mg/g, in fruit samples 0.02-0.39 mg/g), hyperoside (in leaf samples 0.15–7.44 mg/g, in fruit samples 0.02–1.19 mg/g) and isoquercitrin (in leaf samples 0.75–5.24 mg/g, in fruit samples 0.02-0.65 mg/g) was performed. In leaf samples, the total content of identified phenolic compounds ranged from 7.18 to 35.74 mg/g. In fruit, raw material total content of neochlorogenic acid, chlorogenic acid and identified flavonoids varied from 2.24 to 11.19 mg/g. Comparison of raw material samples of Sorbus species according to their quantitative composition of identified phenolic compounds using cluster analysis singularized S. commixta leaf and fruit samples. These contained the highest contents of chlorogenic acid, hyperoside and isoquercitrin, but also the lowest contents of neochlorogenic acid and rutin. The highest contents of neochlorogenic acid were recorded for S. lancifolia leaves, and of rutin for S. anglica leaves.

Patulin (PAT) and citrinin (CTN) are the most common mycotoxins produced by Penicillium and Aspergillus species and are often associated with fruits and fruit by-products. Hence, simple and reliable methods for monitoring these toxins in foodstuffs are required for regular quality assessment. In this study, we aimed to establish a cost-effective method for detection and quantification of PAT and CTN in pome fruits, such as apples and pears, using high-performance liquid chromatography (HPLC) coupled with spectroscopic detectors without the need for any clean-up steps. The method showed good performance in the analysis of these mycotoxins in apple and pear fruit samples with recovery ranges of 55–97% for PAT and 84–101% for CTN, respectively. The limits of detection (LOD) of PAT and CTN in fruits were 0.006 µg/g and 0.001 µg/g, while their limits of quantification (LOQ) were 0.018 µg/g and 0.003 µg/g, respectively. The present findings indicate that the newly developed HPLC method provides rapid and accurate detection of PAT and CTN in fruits.

The aim of this study was to evaluate the effect of 6-benzylaminopurine (BAP) separately and in interaction with auxins on the change in the qualitative and quantitative composition of flavonoids in the raw materials of regenerating plants Iris sibirica L. Cambridge grade in comparison with aeroponic and intact raw materials using the method of high-performance liquid chromatography. Raw materials of I. sibirica Cambridge variety obtained in vitro culture had a richer qualitative composition of flavonoids than intact plants. The dependence of the accumulation of flavonoids on the concentration of 6-benzylaminopurine in nutrient media was noted. The presence of 13 compounds was observed in extracts of 70% ethyl alcohol from regenerating plants grown at the lowest concentration of BAP (1.0 µM) within the experiment. In quantitative terms, the flavonoid apigenin was maximally determined on a medium with BAP 1 µM, and kaempferol - on media with BAP 5.0 µM, supplemented with auxins. For a medium with 7.5 µM BAP, the lowest variety of compounds was observed (9) and the lowest kaempferol content. Auxins influenced the synthesis of flavonoids. The amount of flavonoids in all variants of the experiment increased by an average of 13% in the presence of auxins. The stages of the technological process of obtaining raw materials I. sibirica Cambridge variety on the basis of clonal micropropagation and cultivation in aeroponics conditions allowed to obtain raw materials that do not contain heavy and toxic metals, are not infected with pathogens and pests. With 1 m2 of useful area of aeroponics for 1 year, it is possible to collect 5 times more raw materials than with field cultivation. According to the qualitative composition of phenolic compounds, aeroponic raw materials are identical to intact plants.

The paper presents the methodology of preparation of samples of oilseeds, lettuce, apples for research by chromatographic control of xenobiotics of the following chemical groups of pesticides: benzimidazole derivatives, anilinopyrimidine derivatives, bipyridylium derivatives. The implementation of the following processes is considered: homogenization of the sample, purification of the extract by solid-phase or liquid-liquid extraction, obtaining a plant extract, obtaining an extract of analytes. For fine-grained homogenized samples of sunflower seeds, the optimal ratio of raw material -extragent is 1:20, for pasty homogenized samples of apple fruit - 1:10, for liquid samples of homogenized lettuce - 1: 5. Analysis of the distribution of xenobiotics in the system octane/water, the dipole moment of solvents allowed to determine the extractants that are able to dissolve and remove xenobiotics from raw materials. It was found that a mixture of acetonitrile and methanol (4: 1) should be used to remove benzimidazole derivatives and anilinopyrimidine derivatives, bipyridylium derivatives are best extracted with methanolic trifluoroacetic acid (9.5: 0.5). Quantitative analysis of xenobiotics content in extracts obtained from samples artificially enriched with xenobiotics was performed. The most complete xenobiotics were removed from samples of plant products containing traces of fat. The most difficult process of sample preparation is the process of obtaining sunflower seed extract. The content of xenobiotics in extracts obtained from samples artificially enriched in analytes is influenced by the temperature at which the process takes place and the duration of extraction. Based on the chemical composition of the sample matrix and the list of analytes, the conditions of the variable component of the methodology are proposed: obtaining plant extract under the action of selective solvents, homogenized raw material-solvent with constant stirring of the extraction system at 180-200 rpm, or under the action of ultrasonic vibrations with a frequency of 37 kHz from 4°C to 25°C for 5-25 minutes. The control of the qualitative and quantitative composition of the studied plant extracts and analyte extracts was investigated by the methods of high-performance liquid and gas chromatography (liquid and gas) with mass-selective detectors.

Abstract Anthocyanins are water-soluble pigments responsible for red, pink, purple or blue coloration in the flesh and/or skin of apple fruit. Since consumers prefer anthocyanin rich fruits due to their health benefits, anthocyanin content is an important trait for marketability of apples. Synthesis and accumulation of anthocyanins are controlled by environmental and genetic factors such as transcription factors (TFs). Two-repeat (R2R3) MYB TFs are involved in the regulation of anthocyanin biosynthesis in plants. In this study, the expression of the MdMYBA and MdMYB3 genes encoding R2R3 type MYB TFs were analyzed in apple cultivars with fruit skin color from green to dark red at different growth stages. Fruit samples were collected from “Scarlet Spur”, “Galaxy Gala”, Golden Delicious” “Granny Smith” apple cultivars with dark red, light red, yellow and green fruits, respectively, at four different time periods after full-bloom. Total RNA was isolated from the peel of the collected fruits and the expression of the MdMYBA and MdMYB3 genes was analyzed by real-time RT-PCR. The expression of the MdMYBA gene started to increase at 92 DAFB and thereafter in red-skin apples; however, no expression was observed at any time points in yellow or green-skin apple cultivars. On the other hand, the MdMYB3 gene was expressed in red-skin and yellow-skin apple cultivars starting at 55 DAFB, but no expression was observed in green apple cultivar at any time of fruit maturation. The expression levels of the MdMYBA and MdMYB3 genes varied in apple fruits with different skin coloration indicating that they play a role regulation of the anthocyanin biosynthesis in apple cultivars during fruit maturation.

Mushrooms have been used as part of the average diet and as a nutraceutical for thousands of years due to their immense health benefits. The purpose of this study was to develop a simple, fast, accurate, specific, reproducible, and robust chromatographic method to identify and quantify two water-soluble vitamins: thiamine (B1) and riboflavin (B2) in mushrooms. The method employed for qualitative and quantitative analysis of these vitamins was Reversed Phase-High Performance Liquid Chromatography (RP-HPLC) equipped with Ultraviolet–Visible (UV-Vis) Detector. The extraction process involved acid hydrolysis followed by enzymatic dephosphorylation with takadiastase enzyme. Chromatographic separation was achieved with a Shimadzu prominence HPLC system using isocratic elution mode on a Waters Xterra® MS C-18 column (4.6mm × 150mm, 5 μm) integrated with a XBridge® BEH C-18 Guard column (2.1mm × 5 mm, 5 μm). The mobile phase of this study consisted of buffer and methanol in the ratio of 80:20, where the buffer contained sodium-1-hexanesulfonate, glacial acetic acid, methanol, and pH adjusted to 3.0 with diethylamine. Vitamins were detected simultaneously at their lambda max wavelengths B1: 245nm and B2: 268nm using dual-wavelength UV detection technique to get their highest response. The proposed method was found to be specific, linear R>1.0, accurate, precise (% recovery ± SD; B1:104.45±4.5 and B2: 104.88±2.04), sensitive, (limit of detection for B1 and B2 was 0.043 and 0.029 μg/mL, respectively), and robust for mushrooms analysis. No coeluting peaks were observed at the retention time of the vitamins and all the peaks were spectrally homogenous. The standard and sample solutions were found to remain stable at cold temperature for 72 hours. In summary, our data suggest that the proposed method could be used in food industries to monitor the product quality during routine quality control purposes.

High-performance liquid chromatography method has been used to evaluate qualitative and quantitative composition of certain phenolic compounds obtained from areal parts of Artemisia dracunculus L. introduced in Zhytomyr Polissya. 31 phenolic compounds have been detected, among which the following flavonoids were identified: rutin (1.30±0.04 mg/g), luteolin-7-glycoside (0.34±0.03), apigenin-7-glycoside (0.30±0.01) and isochlorogenic acid (0.16± 0.02 mg/g), where rutin was the dominant component. The total amount of phenolic compounds in air-dried raw material constituted 51.24±0.12 mg/g (5.12%). The employed chromatography analysis of phenolic compounds from Artemisia dracunculus areal parts shows that the plant may be considered as a valuable source of biologically active compounds of phenolic origin. Phenolic compounds are likely to determine the antimicrobial properties of the plant, established earlier. Further in-depth study and cultivation of Artemisia dracunculus in Zhytomyr Polissya have a great potential for pharmaceutical and food industries, cosmetics and development of therapeutic antioxidant diets.
