Studies On Quality Standards Of Cultivated Herbal Erigerontis And Decoction Pieces

"Chinese pharmacopoeia" 2010 edition contains of wild for Erigerontis Herba is the dry herb of Erigeron breviscapus(Vant.) Hand.-Mazz. Processed in spring or autumn and dried in the shade. Its main function is activating blood criculation to dredge meridian and relieve the pain, removing pathogenic wind and dampness.Yunnan Erigerontis Herba production accounted for 95% of the nation, is given priority to with honghe qianshan biotechnology company, are gradually formed the scale. Clinically, most are using Erigerontis Herba cultivation. Erigerontis Herba leaf cultivation is rich, hypertrophy, and scutellarin content high. It is the development and utilization of excellence resources.There is no existing national standards of cultivated herb Erigerontis. It is established the quality standards of cultivated herb Erigerontis leaves. Entrusted by honghe qianshan biological company, The project name:Erigerontis Herba series slices standard research. This thesis also made the Erigerontis Herba leaf powder quality standards.In this thesis, Erigerontis leaves used by high performance liquid chromatography(HPLC). Total flavonoids has been determined in cultivated herb Erigerontis leaves by ultraviolet visible spectrophotometer. The result validated by analytic method showed that proposed methods were accurate and reproducible.This paper compares the scutellarin and total flavonoids content differences between the different regions,different medicinal parts, different drying methods of cultivated herb Erigerontis leaves. And there are scutellarin and total flavonoids content differences among the different regions, different medicinal parts, different drying methods of cultivated herb Erigerontis leaves. At the same time, the chemical constituents of Erigeron breviscapus flowers were studied, providing a theoretical basis for development and utilization of Erigeron breviscapus flowers.It is helpful for the actual production work. It ensured effective in the clinical medication, controlled and evaluated intrinsic quality of cultivated herb Erigerontis leaves safely and scientifically, effectively. It provided technical support for the sustainable development of Erigerontis herbal industry, better for the clinical and pharmaceutical services.
