CHEMICAL INVESTIGATION OF GENUS HEDYOTIS II. ISOLATION AND IDENTIFICATION OF IRIDOIDS FROM HEDYOTIS CHRYSOTRICHA

    摘要
  • 摘要: 从中药黄毛耳草(Hedyotis chrysotricha)中分离鉴定出10个环烯醚萜类化合物,其中8个已知物为:车叶草甙(asperuloside,1),鸡屎藤甙甲酯(scandoside methyl ester,2),车叶草酸(asperulosidic acid,3),去乙酰车叶草酸(deacetyl asperulosidic acid,4),马钱子素(loganin,5),去乙酰车叶草甙(deacetylasperuloside,6),乙酰鸡屎藤甙甲酯(acetyl scandosidemethylester,7),6β-羟基京尼平(6β-hydroxy-genipin,8);2个新化合物命名为耳草甙(hedyoside,9),6′-乙酰车叶草甙(6′-acetylasperuloside,10)。除车叶草甙外均为首次从该植物得到,6β-羟基京尼平为首次从天然界发现。

     

    Abstract: Many species of genus Hedyotis (Rubiaceae) were used as folk medicine for treatment of cold, inflammation, cancer and etc. in China. The alcoholic extract of the whole plant of H.chrysotricha showed good hepatoprotective effects. From the alcocholic extract ten iridoids were isolated and their structures were elucidated as: asperuloside (1), scandoside methyl ester (2), asperulosidic acid (3), deacetyl asperulosidic acid (4), loganin (5), deacetyl asperuloside (6), acetyl scandoside methyl ester (7), 6β-hydroxy-genipin (8) and two new compounds named hedyoside (9) and 6′-acetylasperuloside (10), by means of chemical and spectral methods.
