黃花馬纓丹莖部成分之研究

Constituents from the Stems of Lantana Camara (Ⅲ)

本研究由黃花馬纓丹Lantana camara Linn. （yellow taxa） 莖部分離得到十二個成分，經光譜分析確定其結構分別為phytosterols （1）, β-sitosterol-3-O-β-D-glucoside （2）, 3β-hydroxystigmast-5-en-7-one （3）, oleanonic acid （4）, oleanolic acid（5）, lantadene A （6）, lantadene B （7）, 22 β-angeloyloxylantanolic acid （8）, lantanilic acid （9）, betulonic acid （10）, betulinic acid （11） 及 pomolicacid （12）。 其中3β-hydroxystigmast-5-en-7-one （3） 是馬纓丹屬植物文獻上未成報導的成分。The known triterpenoids, oleanonic acid (4), oleanolic acid (5), lantadene A (6), lantadene B (7), 22β-angeloyloxylantanolic acid (8), lantanilic acid (9), betulonic acid (10), betulinic acid (11) and pomolic acid (12), 3β-hydroxystigmast-5-en-7-one (3), β-sitosterol-3-O-β-D-glucoside (2) as well as a mixture of campesterol (1a), stigmasterol (1b) and β-sitosterol (1c) were isolated from the stems of the yellow flowering taxa of Lantana camara L. The structures of these compounds were established by usual spectroscopic methods.
