Abstract

The invention discloses a determination method for the content of mussaendoside G in the medicinal material Mussaenda pubescens. According to the invention, high-performance liquid chromatographic determination is carried out with the Mussaenda pubescens glycosides G as a contrast and a mixture of acetonitrile and water / 0.01% phosphoric acid as a mobile phase, wherein the ratio of acetonitrile to water / 0.01% phosphoric acid is 25-40: 60-75. The method perfects quality testing standards of the medicinal material Mussaenda pubescens and lays a foundation for establishment of the quality standards of the medicinal material Mussaenda pubescens. The determination method provided by the invention selects the mussaendoside G in the medicinal material Mussaenda pubescens as an index for content determination, has the advantages of high precision, good reproducibility, good stability, high recovery rate and accurate determination results, and can effectively control the quality of the medicinal material Mussaenda pubescens so as to ensure safety and effectiveness of clinical medication of the medicinal material Mussaenda pubescens.

Description

technical field [0001] The invention belongs to the technical field of quality control of medicinal materials, and relates to aureoside G, in particular to a method for determining the content of aureoside G in the medicinal material Aurea japonica. Background technique [0002] Mussaenda pubescens Ait.f. is the dry stem and root of Mussaenda pubescens Ait.f., which has the effects of clearing away heat and relieving heat, cooling blood and detoxifying. It is widely used in Lingnan area, mainly for treating colds, heatstroke, nephritis, edema, For sore throat, bronchitis and other diseases, Yuye Jiedu Granules, a well-known domestic brand of clearing fire and anti-inflammatory drugs, and Yuye Jinhua in Yuye Qinghuo Tablets are all used as monarch drugs. [0003] It is reported in the literature that the medicinal material of Jade Yejinhua mainly contains terpenoids, triterpenoid saponins and other components. Yuyejinhua is recorded in the first volume of "Quality Standards ...
