The purpose of this study is to determine the possibility of using Pueraria flos as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Pueraria flos a were measured. The contents of carbohydrate, crude protein, crude lipid and ash were 69.2%, 19.9%, 2.2% and 8.9%, respectively, and calories was 340.4 ㎉. Total dietary fiber was 85.1% of total carbohydrates. The percentages of water soluble dietary fiber to insoluble dietary fiber were 12.0% and 46.7%, respectively. The protein contained 18 different kinds of amino acids. The contents of essential and non-essential amino acids were 5.0 g and 6.7g. The Ca was the largest mineral followed by K, Mg, and P, which means Pueraria flos is alkali material. The contents of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids were 25.37%, 33.61% and 35.68%, respectively. Therefore, the amount of the total unsaturated fatty acid was higher than that of any other plant. The antioxidant activity of 70% ethanol extract and fractions of the Pueraria flos has been determined by the scavenging of the stable radical DPPH; the result showed that the ethyl acetate fraction was the most active, as the amount required for 50% reduction of DPPH after 30 mins (RC<SUB>50</SUB>) was 109.9 ㎍, followed by 70% ethanol extract (217.3 ㎍), hexane fraction (134.5 ㎍), chloroform (116.7 ㎍), butanol faction (129.8 ㎍) and aqueous fraction (473.5 ㎍).
