对菝葜根茎进行了植物化学研究,分离并鉴定了8种木脂素苷,包括5种新的木脂素,即(7S, 8R, 8’r)- 4,4’,9-三羟基- 3,3’,5,5’-四甲基- 7,9’-环氧木素-7’- 1 -4’-o -β-d-葡萄糖吡喃苷(1),(7S, 8R, 8’r)- 4,4’,9-三羟基- 3,3’,5,5’-四甲基- 7,9’-环氧木素-7’- 1 -4 -o -β-d-葡萄糖吡喃苷(2)(7S, 8R)- 4,9,9’-三羟基- 3,3’,5-三甲氧基-4’,7- o -葡萄糖吡喃苷(8),5 ' -新木质素9 ' -O-β-d-葡萄糖吡喃苷(3),(7R, 8R)- 4,9,9 ' -三羟基- 3,5 -二甲氧基-7。4, 8. o。3 ' -新木质素9 ' -o -β-d-葡萄糖苷(4)和(7S, 8R)- 4,9,9 ' -三羟基- 3,3 ‘,5-三甲氧基- 8,4 ’ -氧-新木质素4- o -β-d-葡萄糖苷(5),以及三个已知化合物(6-8)。它们的结构主要基于一维和二维核磁共振波谱数据、ESI-MS以及与文献的比较来确定。化合物1-8对四种人肿瘤细胞系(SH-SY5Y、SGC-7901、HCT-116、Lovo)进行了体外细胞毒活性测试。化合物3和5对Lovo细胞具有细胞毒活性,ic50值分别为10.4 μM和8.5 μM。
Phytochemical investigation of the rhizomes ofSmilax trinervulaled to isolation and structure elucidation of eight lignan glycosides, including five new lignans, namely, (7S, 8R, 8′R)-4, 4′, 9-trihydroxy-3, 3′, 5, 5′-tetramethoxy-7, 9′-epoxylignan-7′-one 4′-O-β-d-glucopyranoside (1), (7S, 8R, 8′R)-4, 4′, 9-trihydroxy-3, 3′, 5, 5′-tetramethoxy-7, 9′-epoxylignan-7′-one 4-O-β-d- glucopyranoside (2) (7S, 8R)-4, 9, 9′-trihydroxy-3, 3′, 5-trimethoxy-4′, 7-epoxy-8, 5′-neolignan 9′-O-β-d-glucopyranoside (3), (7R, 8R)-4, 9, 9′-trihydroxy-3, 5-dimethoxy-7.O.4′, 8.O.3′- neolignan 9′-O-β-d-glucopyranoside (4), and (7S, 8R)-4, 9, 9′-trihydroxy-3, 3′, 5-trimethoxy-8, 4′-oxy-neolignan 4-O-β-d-glucopyranoside (5), along with three known compounds (6-8). Their structures were established mainly on the basis of 1D and 2D NMR spectral data, ESI–MS and comparison with the literature. Compounds1-8were tested in vitro for their cytotoxic activity against four human tumor cell lines (SH-SY5Y, SGC-7901, HCT-116, Lovo). Compounds3and5exhibited cytotoxic activity against Lovo cells, with IC50value of 10.4 μM and 8.5 μM, respectively.
