Five new withasteroids, physachenolides A - E were isolated from the acetone and methanol extracts of leaves, flowers and stems of Physalis chenopodifolia Lam. The structural assignments of these compounds were based on spectral evidence. The absolute configuration of physachenolide A was established by X-ray analysis.
从酸浆叶、花和茎的丙酮提取物与甲醇提取物中分离出了五种新的维管束甾类化合物，即酸浆醇内酯A - E。这些化合物的结构归属基于光谱证据。酸浆醇内酯A的绝对构型通过X射线分析得以确定。
