在第二个生长季节后，在一片古老的、未施肥的干草场中，研究了九个紫金花无性系的次生酚类物质和植物团生产。紫金叶柳是最有前途用于生产草药原料的柳树品种之一。其芽的各个部位的水杨酸盐含量都较高。叶和茎的植物群在无性系之间差异显着，但总变异的70%以上可以通过无性系内植物群的变异来解释。同样，水杨苷、水杨苷、绿原酸 (+)-儿茶素、原花青素和未知物的积累根据来源（组织、个体或克隆）的不同而显着变化，并且在大多数情况下，环境（克隆内）变异几乎与遗传变异（克隆间）一样高。在选择用于生产草药材料的最佳克隆时，应考虑三个主要因素：种植成本、运输成本和提取物生产成本。就水杨酸盐而言，高植物量克隆可能是低质量克隆。
Nine S. MYRSINIFOLIA clones were studied for secondary phenolics and phytomass production in an old, unfertilized hayfield after the second growing season. S. MYRSINIFOLIA is one of the most promising willow species for the production of herbal drug material. Its salicylate content is moderately high in all parts of the shoot. The leaf and stem phytomass varied significantly among clones, but more than 70% of the total variation could be explained by within-clonal phytomass variation. Similarly, the accumulation of salicin, salicortin, chlorogenic acid (+)-catechin, proanthocyanidins, and unknowns varied significantly according to source (tissue, individual, or clone), and in most cases the environmental (within-clonal) variation was nearly as high as the genetic variation (between-clones). In the selection of the best clones for the production of herbal drug material three main factors should be taken account: costs of cultivation, costs for transportation, and costs for production of extracts. A high phytomass clone may be a low-quality clone as far as salicylates are concerned.
