Antioxidant activity and phenolic content in genotypes of Indian jujube (Zizyphus mauritiana Lamk.)
Indian jujube (Zizyphus mauritiana Lamk), an indigenous fruit crop of India has been widely used in traditional medicine for treating various kinds of diseases. Chinese jujube has been studied; however systematic study on Indian jujube is lacking. In this work, 12 commercial cultivars of Z. mauritiana were evaluated for their ascorbic acid (AA), total phenolics (TPH), flavonoids (TF), and total antioxidant activity (AOX). Results indicate that Indian jujube is a good source of ascorbic acid and total phenolics ranging from 19.54 to 99.49 mg/100 g and 172 to 328.6 mg GAE/100 g, respectively. Total AOX ranged from 7.41 to 13.93 and 8.01 to 15.13 μmol Trolox/g in FRAP and CUPRAC, respectively. Principal component analysis was performed to find a linear combination of the functional attributes which would account for most of the variance in the observed attributes. GGE biplots revealed that ZG-3, Elaichi and Gola, are promising genotypes in terms of total phenolics and flavonoids

Not AvailableTen commercial and three exotic/wild cultivars (cvs) grown under Indian conditions were analyzed for
variations in lycopene, b-carotene, total phenolics, quercetin, ascorbic acid and antioxidant activity
(AOX). AOX was measured using three in vitro assays namely ferric reducing antioxidant power (FRAP),
2,2-diphenyl-1-picrylhydrazyl (DPPH) and Trolox equivalent antioxidant capacity (TEAC) assays. The
lycopene content in tomato cvs ranged from 4.31 to 5.97 mg/100 g fw. The wild/exotic cvs had exceptionally
high total phenolic content (141.98 mg/100 g fw), quercetin (56 mg/g fw) and total AOX
(5.39 mmol TE/g fw). Solanum pimpinellifolium, with nearly six times lycopene content than commercial
cvs, may serve as the most desirable gene pool in breeding programmes to develop functional tomatoes.
Results suggest that TEAC may be more useful than DPPH assay for detecting total AOX in tomatoes.Not Availabl
