黃花馬纓丹葉部成分之研究

Constituents from the Leaves of Lantana Camara (4)

本研究由黃花馬纓丹 [Lantana camara Linn. （yellow taxa）] 葉部分離得到十三個成分，經光譜分析確定其結構分別為phytosterols （1）, β-sitosterol-3-O-β-D-glucoside （2）, betulonic acid （3）,betulinic acid （4）, oleanolic acid （5）, lantadene A （6）, lantadene B （7）, icterogenin （8）, lantanilic acid （9）,and ursolic acid （10）, hispidulin （11）, pectolinarigennin （12） 及pectolinarin （13） 。其中pectolinarigenin（12） 及pectolinarin （13） 是馬纓丹屬植物文獻上未曾報導的成分。Eight triterpenoids, betulonic acid (3), betulinic acid (4), oleanolic acid (5), lantadene A (6), lantadene B (7), icterogenin (8), lantanilic acid (9), and ursolic acid (10), three flavonoids, hispidulin (11), pectolinarigenin (12), and pectolinarin (13), as well as β-sitosteryl-3-O-β-Dglucoside (2) and a mixture of campesterol (1a), stigmasterol (1b), and β-sitosterol (1c) were isolated from the leaves of the yellow flowering taxa of Lantana camara L. The structures of these compounds were established by spectroscopic methods and 2D NMR techniques.
