Objective: To study the chemical constituents of Clerodendron philippinum var. simplex.
Methods: The ethanol extract of Clerodendron philippinum var. simplex was isolated and purified by extraction, chromatography on silica gel and recrystallization. The structures of compounds isolated were identified by physicochemical properties and spectral analysis.
Results: Four compounds were isolated and identified as friedelin (1), 25 (27)-dehydroporiferasterol (2), 22-dehydroclerosteryl acetate (3), uncinatone (4).
Conclusion: Compound 2, 3 are isolated form this genus for the first time, Compounds 4 is isolated from this plant for the first time.
