摘要
Introduction The plants of genus Cistanche G. Beck, which belong to Orobanchaceae family, include about twenty species, and there are four species and one variety are distributed in the northwest part of China. The dried fleshy stem of Cistanche genus plant known as ＇Roucongrong＇ in Chinese traditional medicine, has long been used for kidney deficiency, female infertility, morbid leucorrhea, and neurasthenia. Studies on active components and pharmacological activities show that it possesses significant activities in enhancing potency, anti-fatigue, immuno-modulability, etc, and phenylethanoid glycosides are the major active components. Due to excessive exploitation, its natural resources are facing with exhaustion. In order to improve this situation, the plant has been cultivated on a large scale in the northwest part of China. Up to now, the chemical investigations of the cultivated Cistartcbe salsa have not been undertaken. In this paper we report seven phenylethanoid glycosides from the cultivated Cistanche salsa： echinacoside （1）, cistanoside A （2）, acteoside （3）, isoacteoside （4）, 2＇-acetylacteoside （5）, tubuloside B （6）, and eutigoside A （7）. Among them, compound 7 isolated fronl family Orobanchaceae was reported previously, and compounds 1, 2, 3, 4, 5 and 6 from the cultivated Cistanche salsa are reported for the first time.
目的研究人工栽培盐生肉苁蓉(寄主为囊果碱蓬)中的苯乙醇苷类化学成分。方法采用色谱技术分离纯化,根据理化性质和谱学数据鉴定其结构。结果从盐生肉苁蓉栽培品中分离得到7个苯乙醇苷类化合物,分别鉴定为松果菊苷(echinacoside,1)、肉苁蓉苷A(cistanosideA,2)、毛蕊花苷(acteoside,3)、异毛蕊花苷(isoacteoside,4)、2′乙酰基毛蕊花苷(2′acetylacteoside,5)、管花苷B(tubulosideB,6)、1O[2(4羟基苯基)乙基]6O(E)香豆酰基βD吡喃葡萄糖苷(EutigosideA,7)。结论首次对人工栽培盐生肉苁蓉的化学成分进行了研究,分离得到7个化合物,其中化合物7为首次从列当科植物中分得,化合物1-6为在该种植物栽培品中首次报道。
