(syn. Plumeria acuminata W.T.Aiton) afforded a mixture of lupeol (1), 훼-amyrin (2) and β-amyrin (3) in about 8:2:1 ratio. The structures of 1-3 were identified by comparison of their NMR data with those reported in the literature. Keywords: Plumeria rubra, Plumeria acuminata, Apocynaceae, lupeol, 훼-amyrin, β-amyrin. INTRODUCTION heneicosane, benzyl salicylate, tetradeconoic acid, Plumeria rubra L. (syn. Plumeria acuminata W.T.Aiton) octadecanoic acid and phenylacetaldehyde11. In another commonly known as frangipani and locally known as study, the flowers of P. rubra were reported to contain kalachuchi is grown as an ornamental tree throughout the resin, quercetin, and traces of kaempferol and cyanidin Philippines. A number of studies were reported on the diglycosides; the fresh leaves and bark contain plumeride, biological activities of the different parts of P.
