Triterpenoids from Dischidia alboflava whole plant

In this report, phytochemical constituents of Dischidia alboflava (Asclepiadaceae) collected in Bidoup Nui Ba National Park, Lamdong province, Vietnam were investigated for the first time. The isolation process, as well structure elucidation, have been supported by modern techniques like chromatographic (TLC, CC) and spectroscopic (ESI MS, 1D 2D NMR) methods to result six triterpenoids, including β-amirin acetate (1), friedelin (2), 3α-hydroxyglutin-5-en (3), lupeone (4), lupeol (5), 30-norcyclopterospemol (6). Among these, compounds 3, 4, 6 not recorded occur other species before. Notably, identification compound indicated presence cyclotriterpene chemical components, which has reported date.
