Two new pentacyclic triterpenoids lancamarinic acid and lancamarinin have been obtained from the aerial parts of Lantana camara Linn. They were characterized as 22β-acetoxy-3,25-epoxy-3α-hydroxyolean-12-en-28-oic acid and methyl 3,25-epoxy-3α-hydroxy-11-oxo-22β-senecioyloxyolean-12-en-28-oate, respectively, through chemical transformation and exhaustive spectroscopic studies.
从马缨丹地上部分分离得到两个新的五环三萜类化合物,马缨丹酸和马缨丹宁。通过化学转化和详尽的光谱研究,它们分别被鉴定为22β-乙酰氧基-3,25-环氧-3α-羟基齐墩果-12-烯-28-酸和3,25-环氧-3α-羟基-11-氧代-22β-千里光酰氧基齐墩果-12-烯-28-酸甲酯。
