We obtained the stolons of Glycyrrhiza uralensis that maintained their orginal complexed structures in polyvinyl chloride tubes after 17 months’ cultivation. The three-dimentional structures, length, diameter and weight of the stolons were analyzed and Glycyrrhizin (GL) content of each 10 cm piece of the stolons was determined by HPLC assay according to JP.
Though the diameter and weight of the stolon does not change along its length, we discovered GL content of stolons increases when they grow downward in the cultivation tubes; on the other hand, it decreases when growing upward to the surface. Moreover, it was revealed the GL content is constant when the stolons keep growing at the same depth.
