A new 28-norolean-12,17-diene triterpene lantigdienone (1) oxidised at C-11 and C-22 has been isolated from the aerial parts of Lantana camara, along with two known compounds, camarinin (2) and camangeloyl acid (3). The structure of compound 1 was elucidated as 3,25-epoxy-3alpha-hydroxy-22beta-[beta,betadimethylacryloyloxy]-11-oxo-28-norolean-12,17-diene, with the help of spectral studies.
从马缨丹的地上部分分离得到一个新的 28-降齐墩烷-12,17-二烯三萜化合物 lantigdienone（1），该化合物在 C-11 和 C-22 处氧化，此外还分离得到了两个已知化合物，camarinin（2）和 camangeloyl 酸（3）。通过光谱研究，确定了化合物 1 的结构为 3,25-环氧-3alpha-羟基-22beta-[beta,betadimethylacryloyloxy]-11-氧代-28-降齐墩烷-12,17-二烯。
