Abstract
Three known sesquiterpenes, O-methylcacaldienol, 12-(dehydrocacalohastine-14-yl) cacalohastine
and maturinone have been isolated from the roots of Cacalia auriculata dc var. Kamtschatika (Maxim.) Matsumura together with a new norsesquiterpene I. and new compounds V, VI
and VII. β-amyrin and sitosterols were detected by gas chromatography and mass spectrometry.
Aerial parts of C. auriculata var. kamtscbatica suggested noticeable differences in their constituents. So a study of the constituents
of the tuberous roots was undertaken.
The present paper reports the isolation and structure elucidation of 7 sesquiterpenes
(I-VII), isolated by SiO2 column chromatography and further purification on preparative TLC when necessary.
