目的:研究尖瓣瑞香Daphne acutiloba中的化学成分。方法:采用硅胶柱色谱与Sephadex LH-20凝胶柱色谱进行分离纯化,并运用波谱方法对所分离的化合物进行结构鉴定。结果:从尖瓣瑞香中分离鉴定了15个化合物,经波谱解析鉴定为wikstroelide M(1),vesiculosin(2),prostratin(3),7-hydroxy-coumarin(4),7,8-dihydroxy-coumarin(5),isodaphnoside(6),daph-norine(7),rutamontine(8),daphnolin(9),daphneticin(10),(+)-pinoresinol-β-D-glucoside(11),oleodapnone(12),oleodaphnal(13),ergosterol peroxide(14)和cholest-5-en-3β-ol(15)。结论:除化合物4,5和14外其他成分均为首次从尖瓣瑞香中分离得到。
Objective: To study the chemical composition of Daphne acutiloba. Methods: The compounds were separated and purified by silica gel column chromatography and Sephadex LH-20 gel column chromatography. The structures of the isolated compounds were identified by spectroscopic methods. Results: Fifteen compounds were isolated and identified from the genus Cuscutae, and identified as wikstroelide M (1), vesiculosin (2), prostratin (3), 7-hydroxy-coumarin (5) isodaphnoside (6) daph-norine (7) rutamontine (8) daphnolin (9) daphneticin (10) pinoresinol -β-D-glucoside ), oleodaphnal (13), ergosterol peroxide (14) and cholest-5-en-3β-ol (15). CONCLUSION: All the compounds except compounds 4, 5 and 14 were isolated from Cirsium angustifolia for the first time.
