Abstract

The invention provides a method for measuring content of components of prince's-feather herb and belongs to the technical field of medicament content measurement. High performance liquid chromatography is adopted to measure the content of eight compounds, namely catechin, homo-orientin, orientin, quercetin-3-O-(2'-O-alpha-rhamnose)-betal-glucal, texifolin, luteolin-7-O-beta-D-glucoside, quercetin and kaempferide-3-0-beta-3-D-glucoside, in the prince's-feather herb under the same chromatographic condition. Compared with the conventional single component content measuring method, the method of the invention is more integral, characteristic and stable, and provides test basis for further improving the quality of the prince's-feather herb and the re-development and application of the prince's-feather herb. The invention also provides the methods for preparing reference solution and test sample solution.

Description

technical field [0001] The invention relates to a multi-component content determination method of Chinese medicinal materials, belonging to the technical field of content determination of traditional Chinese medicinal materials. Background technique [0002] Orion is the dried fruit ear and leafy stem of Polygonum orientale L., a plant of the Polygonaceae family. Harvested in autumn and sun-dried. It is a commonly used herbal medicine in Guizhou. It was first seen in ancient books such as "Bie Lu", "Ben Cao Tu Jing", "Compendium of Materia Medica" and other ancient books. ", "Chinese Herbal Medicine", "Southern Yunnan Materia Medica" and other documents are recorded. In 1988, it was included in the "Quality Standards of Chinese Medicinal Materials of Guizhou Province" (1988 edition) with "Dried Whole Herb of Orchard (Red Grass)". In 1992, it was included in "Guizhou Traditional Chinese Medicine Resources" with "Polygonum orientalis (Polygonum orientalis, Polygonum chinens...
