从锦灯笼中分离得到5个甾体类化合物，分别鉴定为酸浆素A (1，alkekengilin A)、酸浆素B (2，alkekengilin B)、酸浆苦素D (3，physalin D)、酸浆苦素P (4，physalin P)、4,7-二去氢新酸浆苦素B (5，4,7-didehydro-neophysalin B)。其中酸浆素A (1，alkekengilin A)和酸浆素B (2，alkekengilin B)为新的天然产物。运用现代波谱技术对上述化合物的结构进行了确证。

Five compounds were isolated from the fruits of Physalis alkekengi L。var。franchetiI (Mast.) by silica gel column，D101 macroporous column，Sephadex LH-20 column，ODS column chromatography and HPLC。On the basis of the chemical and spectral methods，the structures of the five compounds were elucidated as alkekengilin A (1)，alkekengilin B (2)，physalin D (3)，physalin P (4) and 4,7-didehydro-neophysalin B (5)。Among these compounds，1 and 2 are two new compounds，and others are known compounds。
