Abstract

Abstract:

Longan seeds were used as materials to analyze nutritional compositions and antioxidant activity. Results indicated that contents of starch, reducing sugar, total sugar and protein in Shixia longan seeds were higher than those in Dawuyuan and Chuliang longan seeds. Ethanol extract of each of the cultivars exhibited good antioxidant activity due to powerful scavenging capacity against DPPH and hydroxyl free radicals. Moreover, scavenging capacities of extract from Shixia longan seeds against DPPH and hydroxyl free radicals were higher than those of Dawuyuan and Chuliang. However, ethanol extract of each of the longan cultivars exhibited weak scavenging capacity against NO2.

Key words: longan seeds, antioxidant activity, total flavonoids
