Campomanesia xanthocarpa var. littoralis, Campomanesia xanthocarpa (Berg), and Campomanesia eugenioides are native fruit plants found in Brazil. Due to the scarce number of controlled scientific studies comparing different native Campomanesia species, this study sought to determine their bioactive compounds and antioxidant properties. C. eugenioides proved to be a rich source of total phenolic compounds, also showing the best antioxidant capacity by the ABTS, DPPH and molybdenum reduction power methods. On the other hand, C. xanthocarpa var. littoralis showed the best results for total flavonoids content, and Iron(II) chelation power. The phenolic compounds contents present in C. eugenioides could be responsible for the best antioxidant activity. This study provides key scientific data regarding the use of valuable fruits from different edible Campomanesia species to produce bioactive ingredients, as well as natural preservatives for food products. Thus, our results contribute to the discovery of the potential application of these native Campomanesia Brazilian fruits, as a natural product with functional and antioxidant properties.

The purpose of this study is to assess and evaluate the physicochemical properties of the seed oils of two Moroccan varieties of watermelon “Citrullus lanatus” extracted by three different techniques, a mechanical process using cold press, and two chemical processes using a Soxhlet apparatus and a sonotrode ultrasound assisted extraction (UAE) using n-hexane. The total phenolic compounds (TPC) and antioxidant properties against the DPPH radicals (2,2-diphenyl-1-picrylhydrazyl) were also studied. The seed oils of both varieties of watermelon exhibited high concentrations of unsaturated fatty acids with the predominance of linoleic and oleic fatty acids. The primary sterol was β-sitosterol, and high levels of total tocopherols were observed. Ɣ-tocopherol was the predominant tocopherol in all tested oils. The Citrullus lanatus var. lanatus variety seeds oil exhibited the highest TPC value (89.5 ± 0.06 mg EGA/100 g; EGA: gallic acid equivalent), with 82.4 ± 0.03% DPPH free radical inhibition efficiency. Nevertheless, all tested seeds oils showed a significant amount of total phenolic compounds and a good inhibition against DPPH radicals ranging from 51.1 ± 0.1% to 84.8 ± 0.04%. In addition, the influence of the ultrasonic extraction parameters was studied using two different solvents (n-hexane and the methanol-chloroform mixture), with different particle sizes (500–300 µm), duration (10 and 20 minutes), cycle (1–0.5), amplitude (80–100%) and solvent/seed ratios (1:5 and 1:10), and the seed roasting parameter was also studied. The oil yield was mainly affected by the extraction solvent, then the solvent/seed ratio and the duration, respectively.

Introduction. More attention has been paid in recent decades to extracts and essential oils from various plants as natural antioxidant sources due to their positive effects on food oxidation reactions. Our study aimed to compare the antioxidant activity of aqueous and alcoholic extracts from Salvia leriifolia L. and Linum usitalissmum L.The extracts were subjected to a pulsed electric field with intensities of zero (without pretreatment), 3 and 6 kV·cm–1, and a constant pulse number of 30. For this purpose, parameters such as total phenolic compounds and antioxidant activity were investigated by DPPH and TEAC methods. Results and discussion. Our results showed that a higher intensity of a pulsed electric field pretreatment and the use of an alcoholic solvent significantly raised total phenolic compounds in the extracts and their antioxidant activity at a 95% confidence level. We found significant effects of the plant source (Linum usitalissmum and Salvia leriifolia), pretreatment (pulse electric field at intensities of 0.3 and 6 kV·cm–1), and a solvent (aqueous and alcohol) on the extracts’ antioxidant activity (P < 0.05). In addition, there was a significant correlation between the results of the DPPH and the TEAC antioxidant activities (P < 0.01 and r = 0.932). Conclusion. The total antioxidant activity (based on both TEAC and DPPH methods) and total phenolic compounds extracted from Salvia leriifolia were higher than those from Linum usitalissmum (P < 0.05). Based on the results, the extract obtained from Salvia leriifolia with an alcoholic solvent and a pulsed electric field pretreatment (at 6 kV·cm–1 and 30 pulses) was selected as possessing desired antioxidant properties.

Banana inflorescence is consumed as a traditional Thai cuisine for milk lactation in maternal breastfeeding. In this study, the inflorescence of banana (Musa x paradisiaca) was extracted in various solvents to determine the bioactive compounds and antioxidant activity in 2,2′-azino-bis 3-ethylbenzthiazoline-6-sulfonic acid (ABTS) radical scavenging. A suitable extract was developed into a beverage. We compared the results for the amount of total phenolic compounds and the capability of antioxidants obtained in polar and non-polar solvents. The extract in a high-polarity solvent demonstrated high total phenolic compounds and flavonoids. The bioactive compounds of banana inflorescence contained β- sitosterol, flavonoids, saponin, and other phenolic compounds such as catechin and isoquercetin. The aqueous extract of banana inflorescence was developed to act as a primary beverage ingredient. The beverage containing the aqueous extract of banana inflorescence (BAB) exhibited a brownish-yellow color and displayed high acidity and high total phenolic compounds, which are responsible for the antioxidant activity. The food processing of BAB showed no contamination of microbial pathogens. From our results, we concluded that banana inflorescence is a beneficial health food supplement for general consumers. Additionally, the beverage provides convenience and an alternative drink for postpartum mothers who breastfeed for their infants.

Background: Thinking about something new that is important for consumer health is a great concern to all those interested in the dairy industry and its products. Husk Tomato is a promising nutritious fruit rich in minerals, vitamins, and antioxidant compounds. Aim: The objective of this study is to evaluate Husk Tomato Juice (HTJ) constituents, its antimicrobial activity and antioxidant properties. Then utilize it for producing stirred probiotic yogurt (SPY) as a novel fermented product. Methodology: The main components and sugars of fresh HTJ were analyzed using High Performance Liquid Chromatography (HPLC). Antioxidant activity by DDPH (2, 2-diphenyl-1picrylhydrazil) test as well as total phenolic compounds were also determined. Four treatments of SPY fortified with 20, 30, 40 and 50% (v/v) HTJ & Lb. casei FEGY9973 (as probiotic bacteria) were prepared and served as T1, T2, T3 and T4 respectively were compared against control without juice. Results: Data revealed that the main compounds of HTJ were Sinapic (8.170 µg/ml), Protocatechuic (6.344 µg/ml) and Cinnamic (4.660 µg/ml). Contents of Fe, Mg, Na and Ca were 1.766, 1.627, 7.436 and 12.14 mg/100 g. Antioxidant activity and total phenolic compounds of fresh HTJ were 68.88% and 319.15 ppm respectively. It was found that HTJ had powerful antimicrobial activity against both of Y. enterocolitica and Ent. faecalies. On the other hand, data revealed that the antioxidant activity of fresh SPY samples were significantly (p<0.05) higher 67.66, 76.93, 69.34 and 69.59% for T1, T2, T3 and T4 in order, compared to control sample (66.57%). While, appearance scores had no significant (p>0.05) for all samples in fresh, 5 and 10 days of storage. All treatment samples possessed acceptable sensory properties. Conclusion: It could be conducted that SPY fortified with 20 and 30% HTJ had been successfully produced as a healthy dairy product.

SummaryTwo oat (Avena sativaL.) and ten naked oat (Avena nudaL.) cultivars grown on an experimental farm in two consecutive years were analyzed for their content of β-glucan, ash, fat, protein and Osborne protein fractions. Concentration of the antioxidant substances avenanthramides, tocopherols, tocotrienols and total phenolic compounds was analyzed. The antioxidant capacity of the oat cultivars was studied by ABTS•+-scavenging assay and FRAP assay. Cultivar Vazec and conservation cultivar Klimt showed high contents of fat, avenanthramides and total phenolic compounds, as well as a high antioxidant capacity. Klimt also had a high total protein content, and the highest proportion of avenanthramide 2c, which has the highest antioxidant activity of the analyzed avenanthramides. On the other hand, Klimt was also relatively low in β-glucan and tocopherols and tocotrienols. The two cultivars of husked oat, Effektiv and Max, have high yields and low prolamin contents, but showed poor results in all analyzed antioxidant parameters. Comparison of the two cultivation periods showed large differences in many of the analyzed parameters. The hot, dry climate of 2015 had negative influences on the nutritional quality of the oat, especially concerning the antioxidant properties. No cultivar could be identified that was robust against these climatic influences.

Malus Baccata

Crab apple (Malus baccata (L.) Borkh.) was mainly distributed in Europe as an ornamental plant, but the nutritional properties of its edible fruits were not fully revealed. The aim of the current study was to characterize the phytochemical composition of ripen carb apple fruits and to evaluate their nutritional and antioxidant potentials. The fruits were assayed for moisture and ash content, proteins, lipids, carbohydrates, titratable acidity (TA), pH, total phenolic compounds and natural pigments. Among the analyzed carbohydrates cellulose was found in the highest content (6% dw), followed by sugars (sucrose, glucose and fructose) and 1.8 % dw uronic acids. The total chlorophylls and carotenoids contents in their fruits were 6.51 and 4.80 μg/g fw, respectively. Total monomeric anthocyanins were not detected. The highest content of total phenolic compounds (2.67 mg GAE/g fw) was found in 95 % ethanol extract from fruits, while the total flavonoids were relatively low – 0.1 mg QE/g fw. DPPH assay (17.27 mM TE/g fw) and FRAP assay (14.34 mM TE/g fw) demonstrated in vitro antioxidant activities of crabapple. Malus baccata fruits were evaluated as a rich source of dietary fibers and phenolic compounds with significant antioxidant potential that could be used in human nutrition.
