Abstract:AIM: To study the chemical constituents from the aerial part of Callicarpa kwangtungensis Chun. METHODS: The chemical constituents were isolated and purified via silica gel and Sephadex LH-20 column chromatography as well as recrystatlization. Their structures were determined on the basis of spectral analysis and physico-chemicat properties. RESULTS: 13 compounds were isolated and identified as five flavones: 5, 4'-dihydroxy -3, 7, 3'-trimethoxyflavone(1), rhamnatin(2), kumatakenin (3), ermanine (4), velutin (5) ; three triterpenoids: oleanolic acid (6), ursolic acid (7), betulinic acid (8) ; three hydroxybenzene acids: salicylic acid (9), syringic acid (10), isovanillic acid (11) and two sitosterols: daucosterol (12) and ,8-sitosterol (13) . CONCLUSION: Compounds 1-5, 8 and 11 were isolated from this genus for the first time while compounds 10 and 12 have been isolated from this plant for the first time.
Keywords:Callicarpa kwangtungensis Chun  Chemical constituents
