防风化学成分的分离与结构鉴定

Isolation and structure identification of chemical constituents from Saposhnikovia divaricata (Turcz.) Schischk

摘要: 防风乙醇提取物经大孔树脂富集后，采用各种柱色谱法进行分离纯化，从中得到14个化合物，根据理化性质和光谱数据鉴定结构为：防风嘧啶(1)，clemiscosin A (2)，5-羟基-8-甲氧基补骨脂素(3)，亥茅酚苷(4)，亥茅酚(5)，紫花前胡苷元(6)，升麻素苷(7)，升麻素(8)，5-O-甲基维斯阿米醇苷(9)，5-O-甲基维斯阿米醇(10)，异紫花前胡苷(11)，腺苷(12)，胡萝卜苷(13)和β-谷甾醇(14)。其中化合物1为新化合物，化合物2为首次从伞形科植物中分离得到，化合物3为首次从防风中分离得到。

Abstract: Fourteen compounds were isolated from the ethanol extraction of Saposhnikovia divaricata (Turcz.) Schischk using column chromatographic methods after enrichment by macroporous adsorptive resins. They were identified as fangfengalpyrimidine (1), clemiscosin A (2), 5-hydroxy-8-methoxypsoralen (3), sec-O-glucosylhamaudol (4), hamaudol (5), nodakenetin (6), prim-O-glucosylcimifugin (7), cimifugin (8), 4′-O-β-D-glucosyl-5-O-methylvisamminol (9), 5-O-methylvisamminol (10), marmesin (11), adenosine (12), daucosterol (13) and β-sitosterol (14) by physico-chemical properties and spectral data. Compound 1 is a new compound. Compounds 2 and 3 were isolated from umbelliferae plants and Saposhnikovia divaricata (Turcz.) Schischk for the first time respectively.
