Abstract

The stem bark of Teclea ouabanguiensis has yielded six triterpenoids, two of which are new. The known compounds were identified spectroscopically as 7-deacetylazadirone (2), 7-deacetylproceranone (3), tecleanin, (4), and lupeol. The novel compounds include the tetranortriterpenoids, 7-deacetoxy-7-oxoazadirone (1), and ouabanginone (5). The biogenetic significance of the presence of these limonoids in T. ouabanguienis is discussed.

摘要

欧阿斑吉特氏特氏木的茎皮已分离出六种三萜类化合物，其中两种是新的。通过光谱鉴定，已知化合物为7-脱乙酰基阿扎迪酮（2）、7-脱乙酰基原茜草酮（3）、特氏木素（4）和羽扇豆醇。新化合物包括四环三萜类化合物7-脱乙酰氧基-7-氧代阿扎迪酮（1）和欧阿斑吉酮（5）。文中讨论了这些柠檬苦素类化合物在欧阿斑吉特氏特氏木中存在的生源学意义。
