The present series of work was carried out in order to extract and isolate poisonous component from the leaves of Tripetaleia paniculata SIEB. et ZUCC. Presence of grayanotoxin series substance was assumed from the toxic symptoms of the leaves to mice and such a fraction was obtained but did not crystallize. At the same time, hexa-consane (?), 1-triacontanol, 1-octacosanoi, ursolic acid, and quercetin were separated and identified. Presence of kaempferol was observed in paper chromatography. A new triterpenoid of m. p. 210-211°, C30H50O (acetate, m. p. 210.5-211°), was also isolated.
