藿香中一种新的二萜类物质的分离及其结构表征
Isolation and Characterization of a New Diterpenoid Constituent from Agastache rugosa
摘要
Abstract
[Objective] To extract and isolate terpenoids from the leaves and branches of wild Agastache rugosa in Qinba mountainous area,and study the structure of those terpenoids. [Method] The powders of Agaslache rugosa leaves and branches were extracted with 95% ethanol.the concrete was dispersed in water and then extracted by petroleum ether,ethyl acetate,butanol in turn,the terpenoids in the ethyl acetate extracts were isolated with silica gel column chromatography,and then characterized by TLC,IR,UV and NMR. Its crystal structure was also determined by X-ray structure analysis. [Result] This diterpenoid was Longikaurin D,the crystal of Longikaurin D belonged to orthorhombic crystallographic system, space group P2(1)2(1)2(1) .and cell parameters:a =0.845 1(4) ran,6 = 1.061 5(5) nm,c=2.237 1 (10)nm,α =β =γ =90. 00°,Mr = 404.43,V = 2.007(16)nm3,Dc = 1.352 mg/m3,Z =4,F(000) =872,μ=0.103/mm,R1 =0.076 7,ωR2 =0.146 8. [Conclusion] Longikaurin D was extracted from Agastache rugosa for the first time, which provided scientific basis for developing and utilizing the terpenoids in Agastache rugosa.关键词
