目的研究锦灯笼Physalis alkekengi var.franchetii干燥宿萼的化学成分。方法采用硅胶、Sephadex LH-20、ODS柱色谱法进行分离纯化,并根据化合物理化性质和MS、NMR等波谱数据鉴定其化学结构。结果从锦灯笼干燥宿萼85%乙醇提取部位分离得到11个化合物,分别鉴定为4,7-二脱氢新酸浆苦素B()、4′-甲氧基山柰酚()、酸浆苦素O()、25,27-二氢-4,7-二脱氢-7-去氧新酸浆苦素A()、酸浆苦素G()、对香豆酸()、酸浆苦素E()、4,7-二脱氢酸浆苦素B()、酸浆苦素D()、6,6′,7,7′-四羟基-5,5′-双香豆素()、木犀草素-7-O-α-D-葡萄糖苷()。结论化合物和为首次从茄科中分离得到,化合物为首次从酸浆属中分离得到,化合物和为首次从该植物中分离得到。
Objective To study the chemical constituents of dried calyx from Physalis alkekengi var. Franchetii. Methods The compounds were isolated and purified by silica gel, Sephadex LH-20 and ODS column chromatography. Their chemical structures were elucidated on the basis of physicochemical properties and MS, NMR and other spectroscopic data. Results Eleven compounds were isolated from 85% ethanol extract from the dried calyx of Jin lantern and identified as 4,7-didehydrooctanoid (), 4’-methoxy-kaempferol Bitter O (), 25,27-Dihydro-4,7-didehydro-7-deoxyxinacetoprin A (), psicin G Serin (), 4,7-didehydroacetone B (), clopidogrel D (), 6,6 ’, 7,7’-tetrahydroxy-5,5’- Lutein (), luteolin-7-O-α-D-glucoside (). Conclusion The compounds were isolated from Solanaceae for the first time. The compounds were isolated from Physalis for the first time, and the compounds were isolated from this plant for the first time.
