目的 研究青龙衣(核桃楸Juglans mandshurica未成熟果实的外果皮)的化学成分及其体外抗肿瘤活性.方法 应用多种色谱方法对青龙衣95％甲醇提取物进行分离纯化,利用NMR、MS等波谱技术结合理化性质进行结构鉴定;通过MTT法,以子宫颈癌细胞(HeLa)、人胃癌细胞(HGC-27)和结肠癌细胞(Ht-29)为目标细胞,检测所得到化合物的体外抗肿瘤活性.结果 从青龙衣95％甲醇提取物的二氯甲烷萃取部位中分离鉴定出了12个化合物,分别为5,5\'-dimethoxybiphenyl-2,2\'-diol(1)、4,17-dimethoxy-2-oxatricyclo[13.2.2.13,7]eicosa-3,5,7(20),15,17,18-hexaene-10,16-diol(2)、3-羟基-1-(3-甲氧基-4-羟基-苯基)-丙基-1-酮(3)、4羟基-3,5-二甲基苯甲酸(4)、(4S)-4-羟基-1-四氢萘酮(5)、(4R)-O-methylsclerone(6)、阿魏酸(7)、(4S)-4,5,8-trihydroxy-α-tetralon(8)、5,8-二羟基-4-甲氧基-α-四氢萘酮(9)、(6R,7E)-4,7-megastigmadien-3,9-dione(10)、3,4\'-dihydroxy-3\'-methoxybenzenepen tanoic acid (11)、vomifoliol (12).结论 其中化合物1～3、6、10～11首次从青龙衣中的得到,并且化合物2、6、8、9为青龙衣中的特有成分.化合物6、10对3种细胞均有良好的抑制作用,化合物1、3、8、9、11对3种肿瘤细胞表现出一定的体外抑制活性,其半数抑制浓度(half maximal inhibitory concentration,IC50)值为6.25～50.2 μmol/L.
