The current study was carried out at experimental farm of ICAR-Central Institute of Temperate
Horticulture, Srinagar during year 2011 and 2012. In this investigation a total ten selections of Husk
tomato were screened for chlorophyll, ascorbic acid, phenolic, flavonoids, anthocyanins attributes and
antioxidant activities (DPPH). Significant differences among antioxidant attributes were detected in
selected husk tomato selections. The range ofchlorophyll a of the tested samples was (1.00-3.28
mg/100g), chlorophyll b (1.03-2.46 mg/100g) and total chlorophyll (2.05-5.17 mg/100g). DPPH %
inhibition varied between 42.54 and 84.65 %; however, total anthocyanins ranged between (1.23 and
5.65) mgcyanidin-3-glucoside Eq·100 g–1 fresh weight. Total phenols varied from (15.65-20.84) mg
gallic acid Eq·100 g–1 and total flavonoids from (20.18-25.93) mg catechin Eq·100 g–1. Total phenols
and DPPH showed close association; however, PCA revealed that the first PC explained 35% of total
variation and was positively associated to Chlorophyll a, chlorophyll b, total chlorophyll, total
antocyanin, total flavonols and ascorbic acid. All of the diverse cultivars were clustered into two clusters
which could be exploited for future qualitative breeding programs in husk tomato. The importance of our
findings would be significant for farmers, breeders, consumers and industries concerning food quality,
disease prevention and healthcare.
