中文摘要: |
运用硅胶、sephadex LH-20等柱色谱,从木蹄层孔菌子实体的乙醇提取物分离得到12个化合物,通过单体的理化性质、NMR和MS技术鉴定单体的结构为3-十六碳酸酯-7,22-二烯麦角甾醇(1),十八烷酸(2),棕榈酸(3),7,22-二烯麦角甾-3-酮(4),麦角甾-7,22-二烯-3-醇(5),5,8-过氧麦角甾-6,22-二烯-3-醇(6),3,3-二甲氧基-7,22-二烯麦角烷(7),28-乙酰白桦脂醇(8),白桦脂醇(9),β-羟基十八烷酸(10),9,10-二羟基十八烷酸(11),瑞香素(12)。采用Alamar Blue法检测单体化合物对人肺癌细胞NCI-H 460和人胃癌细胞SGC-7901的抑制活性。结果表明,化合物4对NCI-H 460细胞株的抑制活性最高,化合物9对SGC-7901的抑制活性最高。 |
英文摘要: |
The compounds from the EtOH-extract of Fomes fomentarius were isolated and purified by using silicagel and Sephadex LH-20 column chromatography. NMR, MS and other spectroscopy were used to identify the structures of compounds. Twelve compounds were determined: ergosta-7,22-dien-3-palmitate (1), stearic acid (2), palmitic acid (3), ergosta-7,22-dien-3-one (4), ergosta-7,22-dien-3-ol (5), 5,8-epidioxyergosta-6,22-dien-3-ol (6), ergosta-7,22-dien-3- one,dimethyl acetal (7), lup-20(29)-ene-3,28-diol,28-acetate (8), betulin (9), 3-hydroxyoctadecanoic acid (10), 9,10- dihydroxystearic acid (11), daphnetin (12). The anti-tumor activities against NCI-H 460 and SGC-7901 were evaluated by Alamar Blue method, and the results showed that compound 4 had the highest antitumor activity against NCI-H 460 and compound 9 against SGC-7901. |
