Chemical investigation of the dichloromethane extract of Tabernaemontana pandacaqui Poir. flowers has led to the isolation of α-amyrin acetate (1), a mixture of α-amyrin acetate (1), lupeol acetate (2) and β-amyrin acetate (3) in about 4:2:1 ratio, α-amyrin fatty acid ester (4), a mixture of ursolic acid (5) and oleanolic acid (6) in about 1:1 ratio, and β-sitosterol (7). The structures of compounds 1-7 were identified by comparison of their NMR data with those reported in the literature. © 2018 Chemical Publishing Co. All right reserved.
