Chemical constituents of Harpullia pendula. II. Further constituents of the bark and leaves

Abstract

Further examination of the bark of Harpullia pendula has led to the isolation, from the light petroleum extract, of stigmasterol; from the ether extract, of a new compound, 15α,16α,22α,28-tetrahydroxy-olean-12- en-3-one, together with the known triterpenes A1-barrigenol, camelliagenin A and 22α-hydroxyerythrodiol. From the acetone extract of the bark and the leaves quebrachitol has been obtained.
