摘要：

Two new triterpenes were isolated from the leaves of Larix kaempferi together with two known compounds, 24-methylenecycloartanone and 24-methylenecycloartanol. A new triterpene-triol, nine known compounds, n-alkyl trans-ferulates and trans-p-coumarates, rheosmin, five stigmastanes and friedelin were isolated from the stem bark. These new compounds were characterized as cycloartan-3,24-dione, 24-methylenecycloartan-3 alpha-ol and lanost-9(11)-en-3 alpha,24S,25-triol on the basis of chemical and spectroscopic evidence.
