| Abstract: |
| The paper studied the main nutrtion component and activity of antioxidant in fruits of P.pyrifolia (Burm.f) Nakai cv.Jinzhuguo.The results showed that:(1)The contents of edible protion,TTS,total sugar and acid in Jinzhuguo fruits were 855.2,176,110.6 and 5.6 g/kg respectively,And it contains 8 kinds of essential amino acids,abundant Vitamin B and mierals;(2)The biological active ingredient contents of total phenolics,flavonoid and chlorogenic acid in fruits were 7.322,0.245 and 0.467 mg/g respectively;(3)The CI50 of scavenging ·OH of juice is 54.54 μL,and its juice could inhibit lipid peroxidation significantly in liver and brain homogenates of rabbit.These indicate that Jinzhaguo fruits have largequantities of nutrition and antioxidant matters,and is worth to be further researched. |
