Three new physalins (1-3) and a new withanolide 7 have been isolated from the whole plant of Physalis minima, along with three known physalins: physalin H (4), isophysalin B (5), and 5beta,6beta-epoxyphysalin B (6). Their structures were deduced on the basis of in-depth spectroscopic analyses. Compounds 1-6 showed significant in vitro leishmanicidal activities (0.92-19.4 microg/ml) against promastigotes of Leishmania major.
从酸浆全草中分离出了三种新的酸浆苦素(1-3)和一种新的睡茄内酯7,以及三种已知的酸浆苦素:酸浆苦素H(4)、异酸浆苦素B(5)和5β,6β-环氧酸浆苦素B(6)。通过深入的光谱分析推断出了它们的结构。化合物1-6对硕大利什曼原虫前鞭毛体显示出显著的体外杀利什曼活性(0.92-19.4微克/毫升)。
