摘要
黄甘草(Glycyrrhiza euycarpa P.C.Li.)是我国学者近年发现的甘草属一新种。本文指道了自甘肃金塔产黄甘草的根及根茎中分得的10种化学成分,根据理化性质和光谱分析,(IR,UV,~1HNMR,^(13)CNMR,MS,CD), 分别鉴定为:芒柄花甙(Ⅰ),甘草素-4'-O-[D-β-D-呋喃芹糖基(1→2)]-β-D-吡喃葡萄糖甙(Ⅲ),异甘草素-4-O-[D-β-D- 呋喃芹糖基(1→2)]-βD-吡喃葡萄糖甙(Ⅲ),南酸枣甙(Ⅳ),佛来心甙(Ⅴ),异佛来心甙(Ⅵ),新西兰牡荆甙Ⅱ(Ⅶ),乌拉尔甘草皂甙甲(Ⅷ),胡萝卜甙(Ⅸ)和根皮酸(Ⅹ)。所鉴定的化合物皆为首次自黄甘草分得,其中南酸枣甙,佛来心甙,胡梦卜甙及根皮酸为首次从甘草属植物中分得。
Huang Gancao (Glycyrrhiza eurycarpa P. C. Li) is a new species discovered recently. Its chemical constituents have not been reported before. This paper reports the isolation of ten camponents (I--X) from its roots and rhizomes collected in Jinta County, Gansu Province. On the basis of physico-chemical constants and spectroscopic (IR, UV, ~1HNMR, ~13CNMR, MS, and CD) analysis, they were identified as ononin(I), liquiritigenin 4′-O-β-D-apio-D-frano- syl-(l→2)-β-D-glucopyranoside(Ⅱ), isoliquiritigenin-4-O-β-D-apio-D-franosyl-(1→2) β-D-glucopyranoside (Ⅲ), choerospondin (Ⅳ), violanthin (Ⅴ), isoviolan thin (Ⅵ), vice- nin-2(Ⅶ), uralsaponin A(Ⅷ), daucosterol (Ⅸ), and phloretic acid (Ⅹ), respectively All of them were isolated from this plant for the first time. Choerospondin, violanthin, daucoste- rol and phloretic acid were not found in this genus before.
