The Difference

The present study examined the correlation between phenolic acids and flavonoids with high rice yield traits of rice. It was observed that the difference of phenolic contents among the tested rice lines occurred only in the vegetative stage. The concentrations of phenolic acids were higher in the rice high yield cultivars than low yield variety in the vegetative stage, but they either decreased dramatically or disappeared during the development stage. Caffeic acid was found only in high yield rice, whereas chlorogenic acid was detected only in low yield rice. Sinapic acid was the dominant phenolic acid in high yield cultivars at vegetative stage (3.7 mg/g), followed by ferulic acid (1.2 mg/g). These findings suggest that caffeic acid, ferulic acid, sinapic acid and chlorogenic acid may play a particular role in forming yield components in rice. The cultivar B3 contained high amount of sinapic acid may be used as a natural source for pharmaceutical use.

Fagopyrum Esculentum Moench

Common buckwheat (Fagopyrum esculentum Moench) is a valuable source of proteins, B vitamins, manganese, tryptophan, phytochemicals with an antioxidant effect, and the natural flavonoid rutin. Due to its composition, buckwheat supports the human immune system, regulates blood cholesterol, and is suitable for patients with diabetes or celiac disease. The study aimed to compare the allocation of selected phenolic acids (neochlorogenic acid, chlorogenic acid, trans-caffeic acid, trans-p-coumaric acid, trans-sinapic acid, trans-ferulic acid) and flavonoids (rutin, vitexin, quercetin, kaempferol) in the leaves, flowers, and grain of buckwheat cultivars of different origin. The content of individual phenolics was determined by the HPLC-DAD method. The results confirmed the determining role of cultivar on the relative content of chlorogenic acid, trans-caffeic acid, trans-sinapic acid, vitexin, and kaempferol in buckwheat plants. A significantly negative correlation among concentrations of phenolic acids in different common buckwheat plant parts shows that there are different mechanisms of genetic influences on the concentration of phenolic substances in common buckwheat flowers, leaves, and grain. These differences should be taken into account when breeding buckwheat for a high concentration of selected phenolic substances.

This study was conducted to study the influence of plant density and irrigation on the content of phenolic compounds, i.e., phenolic acids and flavonols in cv. ‘Sevilla’ cauliflower curds. Levels of phenolic acids and flavonols were in the range of 3.0–6.2 mg and 25.4–87.8 mg/100 g of dry weight, respectively, depending on plant density and irrigation. Of the phenolic acids, caffeic acid was detected in the highest amount, followed by p-coumaric acid, sinapic acid, gallic acid, and ferulic acid. Of the two flavonols detected, the levels of quercetin were higher than those of kaempferol. The content of the detected phenolic acids (with the exception of ferulic acid) and both flavonols increased with increasing plant density. Furthermore, the concentration of phenolic compounds (with the exception of ferulic acid) was significantly higher under irrigation.

Objective: The aim of this research was to determine and compare phenylpropanoids and fatty acids composition in two plant species, Datura innoxia and Datura stramonium.Methods: Phenylpropanoids and fatty acids composition in leaves and roots extracted from Datura innoxia and Datura stramonium, grown under greenhouse conditions, was analyzed by gas chromatography–electron impact/time of flight-mass spectrometry (GC-EI/TOF-MS) chromatography techniques. Analyses were carried out at the Max Planck Institute for Molecular Plant Physiology of Golm (Germany).Results: We revealed that Datura stramonium (DS) contains hydroxy-hexanedioic acid while hexanoic acid was found in Datura innoxia (DI). Also, two fatty acids are common to both Datura species, hexadecanoic acid and octadecanoic acid, with an almost equal rate between leaves and roots. However, phenylpropanoids composition revealed eight compounds; luteolin, quercetin, trans-caffeic acid, trans-ferulic acid, cis-caffeic acid, cis-4-hydroxy-cinnamic acid, trans-4-hydroxy-cinnamic acid and trans-sinapic acid in DI. However, in DS, five compounds were detected: luteolin, quercetin, trans-caffeic acid, trans-ferulic acid and dihydroferulic acid. Also in both Datura species, phenylpropanoids concentration in leaves was significantly higher than in the roots.Conclusion: Our results showed a difference in phenylpropanoids and fatty acids compositions between the two Datura species, with a significantly higher concentration of phenylpropanoids in Datura innoxia than in Datura stramonium

Abstract Background In the absence of an effective vaccine against malaria, chemotherapy remains a major option in the control of the disease. Then, the recent report of the emergence and spread of clones of Plasmodium falciparum resistant to available antimalarial drugs should be of concern as it poses a threat to disease control. Compounds whose pharmacological properties have been determined and touted for other disease can be investigated for antimalarial activity. Phenolic acids (polyphenols) have been reported to exhibit antioxidant, anticancer, anti-inflammatory, antiviral and antibiotic effects. However, information on their antimalarial activity is scanty. Phenolic acids are present in a variety of plant-based foods: mostly high in the skins and seeds of fruits as well as the leaves of vegetables. Systematic assessment of these compounds for antimalarial activity is therefore needed. Method Using the classical in vitro drug test, the antimalarial activities of five hydroxycinnamic acids, (caffeic acid, rosmarinic acid, chlorogenic acid, o-Coumaric acid and ferulic acid) and two hydroxybenzoic acids (gallic acid and protocatechuic acid) against 3D7 clones of Plasmodium falciparum was determined. Results Among the phenolic acids tested, caffeic acid and gallic acid were found to be the most effective, with mean IC 50 value of 17.73µg/ml and 26.59µg/ml respectively for three independent determinations. Protocatechuic acid had an IC 50 value of 30.08 µg/ml. Rosmarinic acid and chlorogenic acid, showed moderate antimalarial activities with IC 50 values of 103.59µg/ml and 105µg/ml respectively. The IC 50 values determined for ferulic acid and o-Coumaric acid were 93.36µg/ml and 82.23µg/ml respectively. Conclusion The outcome of this study suggest that natural occurring phenolic compounds have appreciable level of antimalarial activity which can be exploited for use through combination of actions/efforts including structural manipulation to attain an increase in their antimalarial effect. Eating of natural food products rich in these compounds could provide antimalarial prophylactic effect.

Bound Phenolics

Pitahaya peel is a good source of bioactive polyphenols. However, the bound phenolics and their antioxidant activity remain unclear. The bound phenolics of pitahaya peel from two red-skinned species with red pulp (RP) and white pulp (WP) were released with different methods (acid, base, and composite enzymes hydrolysis). The results revealed that base hydrolysis was the most efficient method for releasing the bound phenolics from RP (11.6 mg GAE/g DW) and WP (10.5 mg GAE/g DW), which was 13.04-fold and 8.18-fold for RP and 75.07-fold and 10.94-fold for WP compared with acid hydrolysis and enzymatic hydrolysis, respectively. A total of 37 phenolic compounds were identified by UPLC-TOF/MS with most chlorogenic acid, caffeic acid, ferulic acid and p-coumaric acid in RP, whereas chlorogenic acid, caffeic acid, ferulic acid, rutin and isoquercitrin were the main compounds in WP. Regardless of the hydrolysis method, the extracts having the highest phenolic content showed the strongest antioxidant activities. The work shows that hydrolysis methods have a significant effect on the release of phenolics, and the contents of major characteristic bound phenolic compounds are related to the ecological type of pitahaya.

Abstract The main purpose of the study was to determine changes of polyphenol concentrations in hybrids of Nante type carrots during storage. Fresh Nante type ‘Forto’ variety carrots and carrot hybrids ‘Bolero’ F1, ‘Champion’ F1, and ‘Maestro’ F1 were cultivated in the Zemgale region of Latvia. Carrots were stored for six months in air (+3 ± 1 °C, RH = 89 ± 1%) and polyphenol compound concentrations were determined at two month intervals. High-performance liquid chromatography was used to determine concentrations of eight polyphenols in carrots: gallic acid, catechin, epicatechin, caffeic acid, chlorogenic acid, ferulic acid, vanillin, and rutin. Significant differences occurred in polyphenol concentrations of fresh Nante type variety ‘Forto’ carrots and several hybrids (‘Bolero’ F1, ‘Champion’ F1, and ‘Maestro’ F1) during storage. After six months of storage, the concentration of polyphenol compounds of Nante type carrots decreased — caffeic acid by 64.6%, chlorogenic acid — by 37.9% and vanillin — by 81.5%. However, during storage, concentration of some polyphenol compounds increased, as catechin by 30.5%, epicatechin by 85.2%, gallic acid by 48.5% and ferulic acid by 87.9%.

Leaves of Williams pear were collected during the growing season from May to October and the contents of sugars and phenolic compounds were analyzed by high-performance liquid chromatography method. Sorbitol was the major sugar (up to 83.8 g kg-1 DW), followed by sucrose (up to 22.1 g kg-1 DW). Concentrations of glucose and fructose were as high as 12.9 and 9.0 g kg-1 DW, respectively. Leaves contained up to 29 471.9 mg kg-1 DW of chlorogenic acid, followed in concentration by rutin (up to 6789.2 mg kg-1 DW), epicatechin (up to 7378.0 mg kg-1 DW), catechin (up to 3846.5 mg kg-1 DW), vanillic acid (up to 1832.1 mg kg-1 DW), syringic acid (up to 1123.5 mg kg-1 DW), caffeic acid (up to 122.5 mg kg-1 DW) and sinapic acid (up to 94.1 mg kg-1 DW). The significant differences in concentration of sorbitol, sucrose, glucose, and in all analyzed phenolics were observed during the growing season (six sampling dates). The lowest concentrations in the leaf were found at the beginning of the growing season in May and June. The highest contents of sugars were in October, with the exception of sorbitol. During the growing season, total phenolic content first increased, then declined. Chlorogenic acid, rutin and caffeic acid contents increased until July, vanillic acid and sinapic acid until August, and catechin, epicatechin and syringic acid until September. However, total phenolic content dropped by 50% from September to October. Key words: Pear leaves, sugars, phenolics, growing season
