【摘要】 采用色谱技术对苦味西葫芦果实的抗炎活性部位的化学成分进行分离,应用1HNMR、13CNMR确定化合物的结构。从正丁醇萃取部位分离得到4个木脂素化合物:Larisiresinol 4′-O-β-D-glucopyranoside(Ⅰ)、(+)-5′-Methoxy-isolarisiresinol 3α-O-β-D-glucopyranoside(Ⅱ)、Lyoniside(Ⅲ)、Isolariciresinol-9-O-β-D-xylopyranoside(Ⅳ)。化合物Ⅰ、Ⅱ、Ⅲ和Ⅳ均为首次从南瓜属植物中分离得到。更多还原

【Abstract】 To isolate anti-inflammatory chemical constituents from fruits of Cucurbita pepo cv Dayangua,solvent extraction combined with column chromatography was used,NMR spectra were employed for structure identification.Four compounds were obtained and elucidated as Larisiresinol 4′-O-β-D-glucopyranoside(Ⅰ),(+)-5′-Methoxyisolarisiresinol 3α-O-β-D-glucopyranoside(Ⅱ),Lyoniside(Ⅲ) and Isolariciresinol-9-O-β-D-xylopyranoside(Ⅳ).All of these compounds were obtained from Cucurbita genus for the first time.更多还原
