Abstract
OBJECTIVE: To separate and identify the constituents from Clerodendron fragrans. METHOD: The constituents were isolated and purified with chromatographic methods, identified by NMR, MS, IR. RESULT: Beta-sitosterol (1), clerosterol (2), daucosterol (3), caffeic acid (4), kaempferol (5), 5,4'-dihydroxy-kaempferol-7-O-beta-rutinoside (6), acteoside (7) and leucoseceptoside A (8), were isolated and identified. CONCLUSION: Compound 7 and 8 were identified for the first time from Clerodendron fragrans.
