A new cucurbitane glucoside, 23-O-beta-D-glucopyranosyl-7-hydroxy-3-O-malonylcucurbita-5,24-dien-19-al, named momordicine V, has been isolated from Momordica charantia leaves, along with the previously reported compounds, momordicines I, II, IV and 3-O-malonylmomordicine I. The structure of the new compound was established on the basis of spectral analysis, as well as by its conversion to momordicine II by alkaline catalyzed hydrolysis. Momordicine V deterred significantly the oviposition by L. trifolii on host plant leaves treated at 26.16 microg/cm2 leaf surface.
从苦瓜叶中分离出一种新的葫芦烷糖苷，即23 - O - β - D - 吡喃葡萄糖基 - 7 - 羟基 - 3 - O - 丙二酰葫芦巴 - 5,24 - 二烯 - 19 - 醛，命名为苦瓜素V，同时还分离出了之前报道过的化合物苦瓜素I、II、IV和3 - O - 丙二酰苦瓜素I。新化合物的结构是在光谱分析的基础上确定的，同时通过碱性催化水解将其转化为苦瓜素II也证实了该结构。在叶表面以26.16微克/平方厘米处理的寄主植物叶片上，苦瓜素V显著抑制了三叶草斑潜蝇的产卵。
