Abstract:
Six kinds of provenance of Rheum tanguticum collected from Qinghai province as the test materials, which were transplanted under 3 different environments by using complete randomized block design with three replicates. The contents of the chemical components was determined by HPLC. This study aimed at analyzing the effect of genotype, environment and their interactions on the 4 kinds of functional components (phenolic acids, bianthrone, free anthraquinones and combined anthraquinones) in 14 kinds of active components of Rh. tanguticum, in order to provide a theoretical basis for the selection of cultivated Rh. tanguticum in high quality producing area and excellent provenance. The provenance trial showed that the genotype and environment influence on the effect of all kinds of functional components in Rh. tanguticum were significant (<0.05). The content of phenolic acids was mainly influenced by environment, and the other three kinds of functional components were affected by environment and their interactions. The proportion of environment was larger. The cultivation quality of Rh. tanguticum should give priority to environment, then choose a provenance. Sichuan may be beneficial in accumulation of combined anthraquinones in Rh. tanguticum, Gansu may facilitate the binding of free anthraquinone, phenolic acids and bianthrone content. Preliminary inference based on the content and proportion of efficacy components, T4 could be potential special medicinal germplasm that have function of heat-clearing and detoxifying drugs and activate blood circulation to dissipate blood stasis; T3 and T6 could all be potential specialmedicinal germplasms that exist diarrhea attack characters. The results of this study have certain guiding significance for the production of rhubarb precision medicinal materials.
