Abstract

Two novel triterpene esters were isolated from the leaves of Ceriops decandra in addition to 16 known triterpenes: lupenone 3, lupeol 4, betulinaldehyde 5, 3β-Z-coumaroyllupeol 6, 3β-E-coumaroyllupeol 7, 3-epi-betulinic acid 8, betulin 9, betulinic acid 10, 3β-E-feruloylbetulin 11, 30-nor-lup-3β-ol-20-one 12, 3β-E-caffeoyllupeol 13, lup-20(29)-en-3β,30-diol 14, 3β-hydroxylupan-29-oic acid 15, 3β,20-dihydroxylupane 16, and a mixture of oleanolic and ursolic acid 17 and 18. The new compounds were determined by spectroscopic methods to be 3β-E-feruloyllupeol 1 and 3β-Z-feruloyllupeol 2. Compounds 3 and 5–16 were reported for the first time as metabolites of C. decandra.
