石吊兰全草中的一个新菖蒲烷类倍半萜

A new acorane sesquiterpene from Lysionotus pauciflorus

摘要: 目的:研究石吊兰全草的化学成分。方法:采用硅胶、MCI等多种层析柱分离手段。运用NMR和MS等波谱技术鉴定化合物的结构。结果:从石吊兰全草中分离并鉴定了3个化合物:3,10-dihydroxyacoronene(1)、邻苯二甲酸二丁酯(2)和3',5'-二甲氧基4羟基顺式二苯乙烯(3)。结论:化合物1为新的菖蒲烷类倍半萜,为首次从该属植物中分离得到的菖蒲烷类倍半萜类化合物。

Abstract: AIM:To study the chemical constituents of the whole plant of Lysionotus pauciflorus.METHODS:Chromatographic separations on silica gel,Toyopearl HW-40F gel,and MCI gel were used to isolate the compounds.The structures were elucidated on the basis of spectral data.RESULTS:Three compounds were obtained and their structures were identified as 3,10-dihydroxyacoronene(1),bis(2-butylhexyl) phthalate(2) and 3,5-dimethoxy-4-hydroxy-trans-stilbene(3).CONCLUSION:Compound 1 is a new acorane sesquiterpene,this is the first report of acorane sesquiterpenes from the Lysionotus genus.
