摘要
[目的]测定11批盐生肉苁蓉药材水分、灰分、浸出物等质量评价参数。[方法]按照《中国药典》2010年版一部附录中的水分测定第一法、总灰分和酸不溶性灰分测定法、浸出物测定法、重金属检查法和砷盐检查法测定。[结果]盐生肉苁蓉药材水分不宜超过10%,总灰分不宜超过12%,酸不溶性灰分不宜超过1.7%,65%乙醇热浸法浸出物不宜低于45%,重金属(Pb2+)不超过0.000 5%,砷盐不超过0.000 1%。[结论]该试验方法准确方便、高效、重复性好,可作为盐生肉苁蓉质量控制的参考依据。

Abstract [Objective] To develop a scientific method for the quality standards of Cistanche salsa. [Method] Samples which are the content of moisture, ash, extract materials, heavy metals and arsenic were analyzed and determined by appendix IX H, IX K, X A, IX E and IX F, respectively, according to Chinese Pharmacopoeia (I), 2010. [Result] Cistanche salsa contains moisture below 10%, total ash below 12%, acid insoluble ash below 1.7%, heavy metal(Pb2+) below 1.7%, arsenic below 0.0001%, ethanol soluble extractives not less than 45%. [Conclusion] This method was simple, accurate and reproducible. The quality standards can provide a reliable experimental basis for Cistanche salsa.

盐生肉苁蓉(Cistanche salsa (C. A. Mey.) G. Beck)又名肉苁蓉、盐生大芸, 为肉苁蓉属(Cistanche Hoffmg. et Link)列当科(Orobanchaceae)多年生草本寄生植物,主要分布在内蒙、陕西、宁夏、甘肃、青海、新疆,生于沙漠、荒漠及荒漠草原带,喜生于盐碱较重的土壤中,新疆是其中主要产区[1]。盐生肉蓯蓉作为传统维药收载于《维吾尔药志》,性温,温肾生精,润肠通便,健身安神。用于肾虚、阳痿、老年习惯性便秘、体虚引起的眩晕、眼花及腰脚酸痛等疾病,另还可用于食少、腹泻、瘫痪及贫血等症[2]。盐生肉苁蓉中含有大量的苯乙醇苷类、环烯醚萜类、挥发性成分、木脂素类、多糖、生物碱等[3-4],具有增强免疫功能、补肾壮阳、抗氧化抗衰老、抗辐射、通便等作用[4-6],具有很好的开发价值和前途。目前对该属植物的研究主要集中于《中国药典》2010版收录的荒漠肉苁蓉及管花肉苁蓉,对盐生肉苁蓉的研究较少[7]。……
