precursors to the callus cultures of Lithospermum erythrorhizon grown on the Linsmaier—Skoog medium supplemented with IAA and kinetin established that the constituent shikonin is formed via shikimic acid, p-hydroxybenzoic acid, m-geranyl-p-hydroxybenzoic acid and geranylhydroquinone. In a strain of callus culture lacking the capacity to synthesize shikonin and in callus cultures which have had this
摘要 对在补充有 IAA 和激动素的 Linsmaier-Skoog 培养基上生长的 Lithospermum erythrorhizon 愈伤组织培养物施用各种假定的前体,确定成分紫草素是通过莽草酸、对羟基苯甲酸、间香叶基对羟基苯甲酸和香叶基氢醌。在缺乏合成紫草素能力的愈伤组织培养物中,在具有这种能力但由于在补充有 2,4-D 的培养基上培养而失去这种能力的愈伤组织培养物中,高达间香叶基-对羟基苯甲酸的物质生物合成序列已被检测到。尽管用白光照射也阻止了紫草素的产生,但可能仍形成了色素痕迹,原因可能是光线没有到达愈伤组织培养物的最内部。
