Abstract: The aims were to compare the contents of resveratrol(Res), piceide(PD), pterostilbene (PS),ε-viniferin (ε-VF) in the grape leaves of Hongti (‘Vitis vinifera cv. Red globe’) and Zixiangwuhe (‘Vitis vinifera cv. NO.4 Xin nong’) treated with H2O2, and provide the basis for the comprehensive utilization of waste grape leaves. In present study, the detached grape leaves Hongti and Zixiangwuhe were treated with H2O2 solution to investigate the changes of stilbenes contents by HPLC methods. The results showed those stilbenes accumulated significantly in both dose-dependent and time-dependent manners in H2O2-treated leaves. 4 kinds of stilbenes increased 6 times higher than untreated, with 2.5% H2O2 for 48 hours treatment. Stilbenes contents of Hongti grape leaves was relatively high, the maximum contents of the total stilbenes compounds was 138.82μg/g in treated leaves. H2O2-treated detached grape leaves showed notably increase on stilbenes contents than blank.
