肉苁蓉的药用有效成分及其寄生机理的研究进展

Research Progress on the Medicinal Effective Components and Parasitic Mechanism of Cistanche deserticola

肉苁蓉为列当科肉苁蓉属的多年生专性根寄生植物,其寄主为藜科的固沙植物梭梭。肉苁蓉具有多种化学成分,主要有苯乙醇苷类、环烯醚萜类、木脂素类、多糖、生物碱、氨基酸、无机微量元素等。目前,对肉苁蓉寄生机理的研究还不是很深入,主要从肉苁蓉种子的萌发过程,吸器的诱导因子及寄生植物对外源物质的识别3方面简单阐述了其寄生机理。

Cistanche deserticola is a kind of perennial obligate holoparasitic plant,belonging to Cistanche of Orobanchaceae.Its host is a kind of sand-fixing plant——Haloxylon ammodendron of Chenopodiaceae.C.deserticola has many kinds of chemical components,which mainly included phenylethanoid glycosides,iridoids,lignans,polysaccharide,alkaloid,amino acids,inorganic trace elements and so on.At present,the research on the parasitic mechanism of C.deserticola is not very thorough still.Its parasitic mechanism was simply expounded from three aspects of the seed germination process of C.deserticola,the haustellate inducting factor and the identification of parasitic plant on exogenous substance.
