Abstract
| - Fractions of the dried leaves of Licania pyrifoliacontaining triterpenes were investigated, andfour new compounds (1−4) were isolated. Theirstructures were established after detailedNMR spectral studies as 11α-hydroxybetulinic acid,6β-hydroxybetulinic acid, 2α,3β-dihydroxyup-12-en-28-oic acid 3-(3‘,4‘-dihydroxybenzoyl ester), and2α,3β,27-trihydroxylup-12-en-28-oicacid 3-(3‘,4‘-dihydroxybenzoyl ester), respectively.
