摘  要:
采用系统溶剂分离法,制备TLC及光谱分析,对白鲜皮中的活性物质进行了分离和鉴别,以小叶碟添加法对其生物活性进行了监测。结果表明,白鲜皮中主要的活性物质是梣酮。其在浓度为0.11%(质量百分数)时对三龄粘虫幼虫的72 h拒食率和死亡率分别为80.4%和96.6%。

摘  要:
By solvent partition,preparative TLC and spectral analysis,methanol extracts of D.dasycarpus was isolated and identified.The results indicated that a main actives substance with the biological activity was fraxinellone.Its antifeeding rate and death rate of 72 h at 0.11%(mass percent) against Mythimna setarata were 80.4% and 96.6%,respectively.
