结合国内外文献,对唇形科风轮菜属植物近20年来的三萜皂苷与黄酮类成分的结构及波谱学研究内容进行综述.目前已从风轮菜属植物中分离鉴定了42个三萜皂苷和23个黄酮.总结了根据烯碳和羰基碳的NMR核磁数据特征推测三萜皂苷基本结构类型,依据含氧碳及相邻碳的化学位移值确定羟基的取代位置,依据三萜皂苷的碳谱数据鉴定皂苷中糖的种类和连接位置以及黄酮类成分特征性的核磁共振波谱规律.对为进一步鉴定该属植物中三萜皂苷与黄酮类化合物结构以及进行波谱数据的归属具有重要的作用.
This paper reviews domestic and international research progresses in studying the structures and NMR spectral features of triterpenoid saponins and flavonoids in Labiatae Clinopodiura. So far, 42 saponins and 23 flavonoids have been isolated and identified. Base on the NMR data of alkene carbon and carbonyl carbon, the basic structures of triterpenoid saponins can be speculated. According to the chemical shifts of oxygenated carbon and the adjacent carbon, the hydroxyl substitution position can be determined. The type of sugar and connection location can be identified by the carbon spectral date of triterpenoid saponions. Meanwhile, the characteristic spectral features of flavonoids are summarized. NMR spectral characterization of triterpenoid saponins and flavonoids of the Clinopodium will facilitate further identification of new compounds from Clinopodium Linn.
