RESUMEN
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.
RESUMEN
Eight kinds of provenance of Rheum palmatum collected from 4 provinces Sichuan, Ningxia, Gansu, Shannxi as 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 R. palmatum, in order to provide a theoretical basis for the selection of cultivated R. palmatum in high quality producing area and excellent provenance. The functional components of R. palmatum were influenced by genotype and environment. 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 R. palmatum should give priority to environment, then choose a provenance. Sichuan may be beneficial in accumulation of free anthraquinones in R. palmatum, Gansu may facilitate the binding of combined anthraquinone, phenolic acids and bianthrone content. Preliminary inference based on the content and proportion of efficacy components, P2 could be potential special medicinal germplasm that have function of heat-clearing and detoxifying drugs. P6 could be potential special medicinal germplasm that activate blood circulation to dissipate blood stasis. P7 and P1 could all be potential specialmedicinal germplasms that exist diarrhea attack characters. The results of this study have important guiding significance for the production of rhubarb precision medicinal materials.
RESUMEN
As an important herbaceous plant, Scutellaria baicalensis Georgi (Chinese skullcap) is geographically widespread and commonly used throughout the world. In the Chinese medicine market, S. baicalensis has been divided into two primary types, "Ku Qin" (WXR) and "Tiao Qin" (TST). Moreover, TST is also divided into different grades according to the diameter of roots. To explore the distribution patterns of the contents of five biologically activate ingredients (FBAI), we used six-year-old cultivated S. baicalensis and analyzed its growth characteristics as well as the quality difference among different types and diameters in roots. Throughout the entire root, we discovered that contents of the FBAI all initially increased and subsequently decreased from the top to the bottom of the roots. The baicalin content of WXR was less than that of TST. On the contrary, the contents of baicalein, wogonin, and oroxylin A in WXR were up to about two times higher than that in TST. We also found that the 0 to 40 cm part of the S. baicalensis root possessed about 87% of the root biomass and about 92% of the contents of the active ingredients.
