Abstract:
Notoginseng saponin R1; ginsenosides Rg1, Re, Rb1, and Rd; the sum of the five saponins; and underground-part fresh weight (UPFW) of single plants were used as quality evaluation indices for Panax notoginseng (Burk.) F. H. Chen (P. notoginseng). Comprehensive evaluation of P. notoginseng samples from 30 production areas was performed using that MaxEnt model. Spatial pattern changes in suitable P. notoginseng habitats were predicted for current and future periods (2050s, 2070s, and 2090s) using SSP126 and SSP585 models. The results revealed that temperature, precipitation, and solar radiation were important environmental variables. Suitable habitats were located mainly in Yunnan, Guizhou, and Sichuan Provinces. The distribution core of P. notoginseng is predicted to shift southeast in the future. The saponin content decreased from the southeast to the northwest of Yunnan Province, which was contrary to the UPFW trend. This study provides the necessary information for the protection and sustainable utilization of P. notoginseng resources, and a theoretical reference for its application in the quality evaluation of Chinese medicinal products.
摘要:
三七皂苷R1;人参皂苷Rg1,Re,Rb1和Rd;五种皂苷的总和;和单株植物的地下部分鲜重(UPFW)被用作三七(Burk。)F.H.陈(P.三七)。使用MaxEnt模型对30个生产区的三七样品进行了综合评价。预测了当前和未来时期三七适宜生境的空间格局变化(2050年,2070s,和2090)使用SSP126和SSP585型号。结果显示,温度,降水,太阳辐射是重要的环境变量。适宜的生境主要位于云南,贵州,和四川省。预计未来三七的分布核心将向东南移动。云南省的皂苷含量由东南向西北下降,这与UPFW趋势相反。本研究为三七资源的保护和可持续利用提供了必要的信息,并为其在中药产品质量评价中的应用提供理论参考。
