Abstract:
Three new 12beta-hydroxymultiflorane triterpenoid acids, sandorinic acids A-C (1-3), were isolated from the stem bark of Sandoricum indicum together with five known triterpenes (4-8). The structures of 1-3 were elucidated by spectral data interpretation. Compounds 1-8 were evaluated for their inhibiting activity against several tumor cell lines and for their effects on lymphocyte proliferation.
