摘要
从中药黄毛耳草（Ｈｅｄｙｏｔｉｓｃｈｒｙｓｏｔｒｉｃｈａ）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（ｓｃａｎｄｏｓｉｄｅｍｅｔｈｙｌｅｓｔｅｒ，２），车叶草酸（ａｓｐｅｒｕｌｏｓｉｄｉｃａｃｉｄ，３），去乙酰车叶草酸（ｄｅａｃｅｔｙｌａｓｐｅｒｕｌｏｓｉｄｉｃａｃｉｄ，４），马钱子素（ｌｏｇａｎｉｎ，５），去乙酰车叶草甙（ｄｅａｃｅｔｙｌａｓｐｅｒｕｌｏｓｉｄｅ，６），乙酰鸡屎藤甙甲酯（ａｃｅｔｙｌｓｃａｎｄｏｓｉｄｅｍｅｔｈｙｌｅｓｔｅｒ，７），６β羟基京尼平（６βｈｙｄｒｏｘｙｇｅｎｉｐｉｎ，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。
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), 6βhydroxygenipin (8) and two new compounds named hedyoside (9) and 6′acetylasperuloside (10), by means of chemical and spectral methods.
