摘要
从兰科植物Nidema boothii和Scaphyglottis livida中分别分离到两个新的三萜:nidemin(1)、一个修饰的lanostane和9,19- cycloolanosta -24,24-dimethyl-25-en-3 -yl trans - p -hydroxycinnamate(2)。用波谱法对分离物进行了鉴定。x射线分析明确证实了nidemin(1)的结构。
New Triterpenoids from the Orchids Scaphyglottis Livida and Nidema Boothii
Two new triterpenoids, nidemin ( 1 ), a modified lanostane, and 9,19-cyclolanosta-24,24-dimethyl-25-en-3 -yl trans - p -hydroxycinnamate ( 2 ) have been isolated from the orchids Nidema boothii and Scaphyglottis livida , respectively. The isolates were characterized by spectral methods. The structure of nidemin ( 1 ) was unambiguously confirmed by X-ray analysis.
