Study on the Chemical Constituents of Artemisia Myriantha Wall. Ex Bess.

OBJECTIVE To study the chemical constituents of Artemisia myriantha Wall. ex Bess.. METHODS Silica gel column, Sephadex LH-20 column chromatography were used for separation and purification of the compounds and extensive spectral analysis spectrum were employed for structural elucidation. RESULTS Eleven compounds were isolated and identified as arglabin(1), 13-acetoxy-3β-hydroxyl-germacra-1(10)E, 4E, 7(11)-trine-12, 6α-olide(2), eupatorin(3), 8α-acetoxyarg- labin(4), artemyriantholide B(5), artemyriantholide A(6), 4', 5, 7-trihydroxy-6, 3'-dimethoxy flavone(7), casticin(8), 5, 4'-dihydroxy-6, 7, 3', 5'-tetramethoxy flavone(9), arborescin(10), arlatin(11). CONCLUSION Compounds 3, 7~11 are isolated from genus for the first time.
