水茄的化学成分(英文)

Chemical Constituents from Solanum torvum

目的:研究水茄中化学成分。方法:利用硅胶、凝胶和反相等柱层析材料进行分离,通过ESI-MS和NMR波谱方法对分离得到化合物进行结构鉴定。结果:从水茄中分离得到9个化合物(1-9)。结构分别为neochlorogenin 6-O-β-D- qui-novopyranoside(1), neochlorogenin 6-O-β-D-xylopyranosyl-(1→3)-β-D-quinovopyranoside(2), neochlorogenin 6-O-α-L- rhamno-pyranosyl-(1→3)-β-D-quinovopyranoside(3),solagenin 6-O-β-D-quinovopyranoside(4),solagenin 6-O-α-L-rhamnopyranosyl-(1→3)-β-D-quinovopyranoside(5),异槲皮苷(6),芦丁(7),山柰酚(8)和槲皮素(9)。结论:所有化合物均首次从水茄中分离得到。

AIM：To investigate the chemical constituents of Solanum torvum Swartz.METHODS：The compounds were isolated by silica gel,Sephadex LH-20,and Rp-C18 column chromatography.Their structures were elucidated on the basis of spectral analysis of ESI-MS and NMR.RESULTS：Nine known compounds including neochlorogenin 6-O-β-D-quinovopyranoside （1）,neochlorogenin 6-O-β-D-xylopyranosyl-（1→3）-β-D-quinovopyranoside （2）,neochlorogenin 6-O-α-L-rhamnopyranosyl-（1→3）-β-D-quinovopyranoside （3）,solagenin 6-O-β-D-quinovopyranoside （4）,solagenin 6-O-α-L-rhamnopyranosyl-（1→3）-β-D-quinovopyranoside （5）,isoquercetin （6）,rutin （7）,kaempferol （8） and quercetin （9） were isolated from S.torvum.CONCLUSION：All compounds were isolated from S.torvum for the first time.
