On the basis of physicochemical properties and spectral data, they were identified as 9,19-cyclolanost-24-en-3-one (1), cycloartenol (2), friedelin (3), lupenol (4), 3β-acetoxy oleanolic acid (5), oleanolic acid (6), ergosta-4,6,8(14),22E-tetraene-3-one (7), cholest-4-en-3-one (8), 5α,8α-epidioxy-ergosta-6, 9,22E-dien-3β-ol (9), β-sitosterol (10), 6β-hydroxy-stigmast-4-en-3-one (11), cholesterol (12), β-sitosterol-3- O-β-D-glucoside-6′-O-eicosanate (13), trilinolein (14), 1-hentriacontanol (15), docosanoic acid (16), lauryl oleate (17). Except compounds 4, 6, 9, and 10, the others were isolated from the genus Bombax for the first time.
