Abstract

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.
