One new monoterpenoid glycoside, myresculoside (1), and eleven known compounds, were isolated from methanol extract of Myrica esculenta leaves by repeated column chromatography. The effects of these compounds on angiotensin I-converting enzyme (ACE) inhibition were investigated. Compounds 3 and 4 showed the most potent ACE inhibition with rates of 29.97% and 25.63% at concentration of 100 μM, respectively. Compounds 5, 6, and 11 showed weak activity with inhibitory rates of 0.07—1.41% at concentration of 100 μM.
从接骨木叶的甲醇提取物中,通过重复柱层析分离出了一个新的单萜苷——梅果苷(myresculoside,1),以及十一种已知化合物。研究了这些化合物对血管紧张素 I 转化酶(ACE)抑制的影响。化合物 3 和 4 在100 μM浓度下表现出最强的 ACE 抑制活性,抑制率分别为 29.97% 和 25.63%。化合物 5、6 和 11 在100 μM浓度下表现出弱活性,抑制率为 0.07%—1.41%。
