近年来，由于人们对红景天的质量和可持续性的担忧，对红景天药用植物材料的需求有所增加。我们分析了苯丙素类化合物（总rosavins）和红景天苷的含量从3岁的栽培植物的欧洲起源的液体提取物，并绘制了植物部分（根茎与根），基因型，干燥，切割和提取溶剂的化学成分的影响。根茎中红景天苷和总皂苷含量分别为根的1.5-4倍（干重0.3-0.4%）和1.2-3.0%。提取物中的定性决定性苯丙素含量受植物部位、溶剂和基因型的影响最大，而干燥温度和切割条件的重要性较小。我们证明了R.来自不同北欧种源的蔷薇可以在温和的条件下生长，并且鉴定了获得一致的高质量提取物的因素，条件是使用真实的种质并且区分根茎、根和它们的混合物。(c)2012爱思唯尔有限公司保留所有权利。
The demand for plant material of Rhodiola rosea L (Crassulaceae) for medicinal use has increased recently, amid concerns about its quality and sustainability. We have analysed the content of phenylpropanoids (total rosavins) and salidroside in liquid extracts from 3-year old cultivated plants of European origin, and mapped the influence of plant part (rhizome versus root), genotype, drying, cutting, and extraction solvent to chemical composition. Rhizomes contained 1.5-4 times more salidroside (0.3-0.4% dry wt) and total rosavins (1.2-3.0%) than roots. The qualitative decisive phenylpropanoid content in the extracts was most influenced by plant part, solvent, and genotype, while drying temperature and cutting conditions were of less importance. We have shown that R. rosea from different boreal European provenances can be grown under temperate conditions and identified factors to obtain consistent high quality extracts provided that authentic germplasm is used and distinguished between rhizome, roots and their mixtures.
