摘 要:采用多种色谱技术对多花蒿Artemisia myriantha干燥地上部分95%乙醇提取物中的倍半萜类成分进行化学成分研究,分离得到13个化合物。通过理化数据和波谱分析鉴定其结构分别为blumenol A(1),(+)-dehydrovomifoliol(2),(+)-3-hydroxy-β-ionone(3),(3R,6R,7E)-3-hydroxy-4,7-megastigmadien-9-one(4),(-)-10-oxo-isodauc-3-en-15-oic acid(5),isoerivanin(6),eudesmafraglaucolide(7),artanomalide A(8),13-acetoxy-3β-hydroxy-germacra-1(10)E,4E,7(11)-trien-12,6α-olide(9),13-acetoxy-3β-tigloyl-germacra-1(10)E,4E,7(11)-trien-12,6α-olide(10),13-acetoxy-3β-(3-methylbutanoyl)-germacra-1(10)E,4E,7(11)-trien-12,6α-olide(11),3,9-diacetoxy-13-hydroxy-1(10),4,7(11)-germacratrien-12,6α-olide(12),8α-angeloyloxycostunolide(13)。化合物1~6,13为首次从该属植物中分离得到,7~9,12为首次从该植物中分离得到。化合物8对人结肠癌(HCT-8)和人胃癌细胞(BGC-823)有较强的细胞毒活性,IC50分别为2.33,4.53μmol·L^(-1)。The present study is to investigate the chemical constituents from the aerial parts of Artemisia myriantha. The chemical constituents were isolated by column chromatographies over silica gel, Sephadex LH-20, ODS and Semi-prep HPLC, and the structures were identified by NMR and MS data. Thirteen known compounds were isolated and identified as : blumenol A (1), ( + ) -dehydrovom- ifoliol (2), ( + ) -3-hydroxy-β-ionone ( 3 ), ( 3R, 6R, 7E) -3-hydroxy-4, 7-megastigmadien-9-one (4), ( - ) -10-oxo-isodauc-3-en-15- oic acid ( 5 ), isoerivanin ( 6), eudesmafraglaucolide ( 7), artanomalide A ( 8), 13-acetoxy-3/i-hydroxy-germacra-1 (10) E,4E, 7 ( 11 ) - trien-12,6α-olide ( 9), 13-acetoxy-3β-tigloyl-germacra-1 (10) E, 4E, 7 ( 11 ) -trien-12, 6α-olide ( 10), 13-acetoxy-3β- ( 3-methylbu- tanoyl) -germacra-1 (10) E, 4E, 7 ( 11 ) -trien-12, 6α-olide ( 11 ), 3,9-diacetoxy-13-hydroxy-1 ( 10 ), 4, 7 ( 11 ) -germacratrien-12,6α- olide (12), and 8α-angeloyloxycostunolide (13). Compounds 1-6 and 13 were obtained from the genus Artemisia for the first time, and 7-9 and 12 were isolated from this plant for the first time. Compound 8 exhibited selective cytotoxicity against human colon cancer (HCT-8) and human gastric cancer ( BGC-823 ) with ICs0 values of 2. 33 and 4.53 μmol · L^-1, respectively.
