摘　　要：作者通过对隶属于３５个分类单位的近４００号中国鸡皮衣属地衣标本的化学测定，在本文中报道了我国鸡皮衣属地衣中存在的２３个化合物，首次报道鸡皮衣属地衣中存在的有分类意义的化学成分１种，即ｍａｌｏｎｏｐｒｏｔｏｃｅｔｒａｒｉｃａｃｉｄ。化学测定结果表明：至少在中国鸡皮衣属种中，４，５－二氯地衣酮（４，５－ｄｉｃｈｌｏｒｏｌｉｃｈｅｘａｎｔｈｏｎｅ）可能局限于Ｐｅｒｔｕｓａｒｉａ亚属；β－地衣酚类（β－ｏｒｃｉｎｏｌ）化合物是主导的髓层化学成分；β－地衣酚类缩酚酸（β－ｏｒｅｉｎｏｌｄｅｐｓｉｄｅｓ）和β－地衣酚类原岛衣酸型缩酚酸环醚（β－ｏｒｃｉｎｏｌｐｒｏｔｏｃｅｔｒａｒｉｃａcｉｄ－ｔｙｐｅｄｅｐｓｉｄｏｎｅｓ）是Ｐｉｏｎｏｓｐｏｒａ亚属的特征性化学成分，β－地衣酚类斑点酸型缩酚酸环醚（β－ｏｒｃｉｎｏｌｓｔｉｃｔｉｃ　ａｃｉｄ－ｔｙｐｅｄｅｐｓｉｄｏｎｅｓ）是Ｐｅｒｔｕｓａｒｉａ亚属的特征化学成分。形态和化学特征在鸡皮衣属内存在着平行的或独立的进化路线。Twenty three compounds for 35 taxa of Chinese Pertusaria are reported in this paper, among them,malonoprotocetaric acid (examined by A. W. Archer) is a new chemical report for the genus Pertusaria. Theresults of chemical identification indicate that at least among Chinese species examined, 4, 5-dichlorolichexanthonemay be restricted to the subgenus Pertusaria; β--orcinol--type compounds are the more basic chemistry in thegenus; β--orcinol depsides and protocetraric acid--type depsidones are considered to be the characteristic chemistryof the subgenus Pionospora while β~orcinol stictic acid-type depsidones the subgenus Pertusaria. Themorphological and chemical evolution within the genus Pertusaria is independent or parallel.
