This paper aims to extract total quantity flavone from fruit of Solanum photeinocarpum and to study its resistance to oxidation. The effects of solution concentration, temperature, time and ratio of material to liquid on the extraction of total quantity of flavone were discussed. Meanwhile, optimal condition for extraction of total flavone from fruit of Solanum photeinocarpum were chosen through orthogonal experiment. As a result, us-ing 60%ethanol as extractant, extraction for 2.5 h at 70℃ in a ratio of material to liquid 1:12, the yield of extrac-tion can reach up to 3.68 mg·g-1. Extracts from fruit of Solanum photeinocarpum have strong antioxidative effects.
