The monoterpenoid fractions of three endemic Galium ssp. (Rubiaceae) from Sardinia Island were examined and compared with the iridoidic pattern yet known in Galium species. This comparison evidenced theirs endemic characters. In particular, in G.corsicum and in G. glaucophyllum loganic acid was isolated and identified for the first time in Galium genus. In G. schmidii a rare iridoid is present, 10-hydroxy-loganin, whose presence in this genus was evidenced only in G. mollugo and loganin isolated for the first time.
对来自撒丁岛的三种地方特有的拉拉藤属植物（茜草科）的单萜类成分进行了检测，并与拉拉藤属中已知的环烯醚萜模式进行了比较。这种比较证明了它们的地方特有特征。特别是，在科西嘉拉拉藤和灰叶拉拉藤中，首次在拉拉藤属中分离并鉴定出了马钱子酸。在施密迪拉拉藤中存在一种罕见的环烯醚萜，10-羟基马钱子苷，该属中仅在软毛拉拉藤中有此成分，且首次分离出了马钱子苷。
