摘 要:目的:研究延龄草根及根茎中的化学成分。方法:采用硅胶、聚酰胺、反相硅胶C18、Sephadex LH-20柱色谱和制备高效液相色谱等对其85%甲醇洗脱部位进行分离纯化。用MS、1D-NMR及2D-NMR等波谱学方法鉴定化合物的结构。结果:从延龄草的85%甲醇洗脱部位中分离鉴定了10个甾体皂苷类化合物,分别鉴定为:薯蓣皂苷元-3-O-α-L-吡喃鼠李糖基(1→4)-α-L-吡喃鼠李糖基(1→4)-[α-L-吡喃鼠李糖基(1→2)]-β-D-吡喃葡萄糖苷(1)、trikamsteroside E(2)、deoxytrikamsteroside E(3)、(23S,24S,25S)-螺甾-5-烯-1β,3β,21,23,24-五羟基-1β-O-α-L-吡喃鼠李糖基-(1→2)-[O-β-D-吡喃木糖基(1→3)]-O-α-L-吡喃阿拉伯糖苷(4)、trikamsteroside B(5)、27-hydroxytrikamsteroside B(6)、3-乙酰基-偏诺皂苷元(7)、dioscoreanoside I(8)、sileneoside G(9)、intergristerone B(10)。结论:其中,化合物8~10为首次从该属植物中分离得到,化合物1、3、4、6、7为首次从该植物中分离得到。Objective: To investigate the chemical constituents from the roots and rhizome of Trillium tschonoskii. Methods: The85% methanol elution parts from the roots and rhizome of Trillium tschonoskii were separated and purified by polyamide,silica gel,RPC18,Sephadex LH-20 column chromatography and the preparation of high performance liquid. Chemical structures were identified by MS,1D and 2D-NMR experiment. Results: Ten steroidal saponins compounds were isolated and identified as diosgenin-3-O-α-L-rhamnopyranosyl-( 1→4)-α-L-rhamnopyranosyl-( 1→4)-[α-L-rhamnopyranosyl( 1 →2) ]-β-D-glucopyranoside( 1),trikamsteroside E( 2),deoxytrikamsteroside E( 3),( 23 S,24S,25S)-spirostan-5-ene-1β,3β,21,23,24-pentahydroxy-1β-O-α-L-rhamnopyranosyl-( 1 →2)-[O-β-D-xylopyranosyl( 1→3) ]-O-α-L-pyranarabinoside( 4),trikamsteroside B( 5),27-hydroxy-trikamsteroside B( 6),3-acetyl-pennogenin( 7),dioscoreanoside I( 8),sileneoside G( 9) and intergristerone B( 10). Conclusion: Compounds 8 ~ 10 are isolated from this genus for the first time,compounds 1,3,4,6,7 are isolated from this plant for the first time.
