从天山地丁的全草中分离得到一个新的木脂素糖苷天山皂苷A(1)、一个已知的苯丙素苷丁香苷(2)和两个已知的木脂素糖苷苦瓜皂苷C(3)和木脂素苷B(4)。通过核磁共振谱(1H、13C、COSY、HSQC、HMBC和ROESY)和高分辨质谱分析确定了新化合物的结构。三种木脂素1、3和4对人胃癌AGS细胞和HepG2肝癌细胞没有明显的细胞毒作用。这是首次从紫菜属植物中分离得到一个木脂素骨架。
A new lignan glycoside, tianshanoside A (1), together with a known phenylpropanoid glycoside, syringin (2) and two known lignan glycosides, picraquassioside C (3), and aketrilignoside B (4), were isolated from the whole plant of Viola tianshanica Maxim. The structure of the new compound was elucidated by extensive NMR (1H, 13C, COSY, HSQC, HMBC and ROESY) and high resolution mass spectrometry analysis. The three lignans 1, 3, and 4 did not exhibit significant cytotoxicity against human gastric cancer Ags cells or HepG2 liver cancer cells. This is the first report of the isolation of a lignan skeleton from the genus Viola L.
