“…Regarding the anthocyanins concentration, they follow the next order: cyanidin-3,5-di-O-glucoside, cyanidin-3-O-glucoside, and pelargonidin-3-O-glucoside chloride. Similar order was reported for cultivars grown in Georgia [46]. However, this order was different than that reported for Raduníc et al [52], who observed higher values of cyanidin-3-O-glucoside …”

“…Regarding organic acids, citric acid (53) and L-malic acid (52) have been pointed out as the main organic acids in pomegranate juices [46]. In the present study, Mollar de Elche and Cis 127 were the only cultivars with L-malic acid, whereas, citric acid was presented in Valenciana, Cis 127, Katirbasi and Wonderful 2.…”

“…The total monomeric anthocyanin contents in the pomegranate juices were estimated by the pH differential method, following the methodologies used by Bchir et al [45] and Rajasekar et al [46]. The method consisted in using two buffer systems: potassium chloride buffer at pH 1.0 (0.025 M) and sodium acetate at pH 4.5 (0.4 M).…”

“…Several phenolic compounds including gallic acid, protocatechuic acid, chlorogenic acid, caffeic acid, ferulic acid, o ‐ and p ‐coumaric acids, catechin, phloridzin, and quercetin were identified in Turkish varieties . Antioxidant composition of pomegranate varieties from different parts of the world including Turkey, Iran, Persia, China, and Georgia has been reported. But little is known about metabolite concentration in pomegranate genotypes grown under Indian conditions.…”

BACKGROUND Pomegranate fruit is an excellent source of bioactive polyphenolics, known to contribute significantly to human health. India is the largest producer of pomegranate in the world and produces the finest quality fruit with highly desirable consumer traits such as soft seeds, low acidity, and attractive fruit and aril color. Knowledge of the extent of variation in key metabolites (sugars, organic acids, phenolics, and anthocyanins) is key to selecting superior genotypes for germplasm improvement. Relevant information with respect to Indian genotypes is scarce. The present study therefore aims to evaluate quantitatively important metabolites in some cultivars and elite germplasm of pomegranate in India. RESULTS Identification and quantification of primary and secondary metabolites such as sugars, organic acids, vitamin C, polyphenolics, and anthocyanins were conducted using a liquid chromatography – mass spectrometry (LC–MS) platform. Fructose and citric acid were the predominant sugar and organic acid, respectively. Wild genotypes had significantly higher concentrations of organic acids, antioxidant activity, and phenolics, namely punicalagin, ellagic acid, sinapic, and ferulic acid. CONCLUSION Cyanidin and delphinidin derivatives of anthocyanins were more abundant in red aril commercial genotypes. Results suggest that wild‐sour accessions represent a rich source of polyphenolics that can be utilized in future breeding programs to breed healthier varieties, food supplements, and pharmaceutical products. © 2019 Society of Chemical Industry

Background: Pomegranate juice has a number of positive effects on both human and animal subjects. Material and methods: Four groups were used in this study. i: Control group, ii: H 2 O 2 group, iii: Pomegranate juice (PJ) group and iv: PJ + H 2 O 2 group. Following the sterilization method for pomegranate juice (10%) and H 2 O 2 (6% v/v), Saccharomyces cerevisiae cultures were added and the cultivation incubated at 35°C for 72 hours. Fatty acids and vitamin concentrations were measured using HPLC and GC and the total protein bands profile were determined by SDS-PAGE. Results: According to our results statistically significant differences have been determined among the study groups in terms of fatty acids and vitamin (p<0,05). Fatty acid synthesis, vitamin control and cell density increased in groups to which PJ was given in comparison with the control group (p<0,05). Pomegranate juice increased vitamins, fatty acids and total protein expression in Saccharomyces cerevisiae in comparison with the control. Conclusion: Pomegranate juice has a positive effect on fatty acid, vitamin and protein synthesis by Saccharomyces cerevisiae. Accordingly, we believe that it has significantly decreased oxidative damage thereby making a positive impact on yeast development.
