随着天然产物化学的迅速发展，已分离出种类繁多的次生代谢产物，其中许多具有糖苷性质。特别是在过去的二十年中，我们对糖苷的化学、发生和生物发生的知识有了很大的增长[1，2]。大部分的这种努力已经指向大组的O-糖苷以及S-和N-糖苷。由于分析困难，对C-糖苷的研究工作要少得多。C-糖苷是一种特殊类型的糖苷，因为糖苷配基直接连接到糖的α-鼻环的碳1上，而O-糖苷具有半缩醛键。更正确的是将它们视为C-糖基或脱水多元醇，
The rapid development of natural product chemi-stry has led to the isolation of a wide varieLty of secondary metabolites, which, in many cases, was shown to be of glycosidic nature. In particular our knowledge of the chemistry, occurrence and biogenesis of glyco-sides has grown substantially during the last two decades [1, 2]. Most of this effort has been directed toward the large group of the 0-glycosides as well as the S-and N-glycosides. Far less effort has been given to the C-glycosides due to analytical difficulties. C-Glycosides are a special type of glycoside since the aglycone is directly attached to carbon 1 of a pyra-nose ring of a sugar while 0-glycosides possess a hemiacetal linkage. It is more correct to regard them as C-glycosyls or anhydropolyols as proposed by
