从榕树气生根中分离到4个新的环丙基三萜，27- no -3 β - -羟基-25-氧环烷(1)、(22E)-25,26,27-三-3 β - -羟基环烷-22-en-24-al(2)、3 β -乙酰氧基-15 α -羟基-13,27-环烷-11-烯(3)、3 β -乙酰氧基-12 α -甲酰基氧基-13,27-环烷-11 α -ol(4)和(23E)-27-no -3 β -羟基环烷-23-en-25-one(5)。化合物3和4是罕见的13,27-环叔烷型三萜。用光谱学和化学方法对其结构进行了分析。
Four new cyclopropyl-triterpenes, 27-nor-3 beta -hydroxy-25-oxoc3cloartane (1), (22E)-25,26,27-trinor-3 beta -hydroxycycloart-22-en-24-al (2), 3 beta acetoxy-15 alpha -hydroxy-13,27-cyclours-11-ene (3), 3 beta -acetoxy-12 alpha -formyloxy-13,27-cycloursan-11 alpha -ol (4), together with (23E)-27-nor-3 beta -hydroxycycloart-23-en-25-one (5) were isolated from the aerial roots of Ficus microcarpa. Compounds 3 and 4 are rare 13,27-cycloursane-type triterpenes. Their structures were elucidated by spectroscopic and chemical methods.
