Quality control method of rhizoma gastrodiae, decoction piece thereof and rhizoma gastrodiae extract

Abstract

The invention relates to a quality control method of rhizoma gastrodiae, a decoction piece thereof and rhizoma gastrodiae extract. Based on high-performance liquid chromatography, by the aid of a one-standard multi-measurement analysis method, the contents of gastrodin components of gastrodin, p-hydroxybenzyl alcohol, parishin A, parishin B, parishin C and parishin E in the rhizoma gastrodiae arecalculated by relative correction factors, the low-cost gastrodin with stable property serves as an internal standard substance, and six effective components in the rhizoma gastrodiae are simultaneously measured. The multi-index quality control method is high in detection sensitivity, rapid in analysis and good in stability, can objectively, comprehensively and accurately evaluate the quality of the rhizoma gastrodiae, the decoction piece thereof and the rhizoma gastrodiae extract, is of great significance for ensuring the curative effect of the rhizoma gastrodiae and can solve the problems that parishin component reference substances are unstable, high in price and the like, and the quality of the rhizoma gastrodiae, the decoction piece thereof and the rhizoma gastrodiae extract cannot becomprehensively controlled.

Description

technical field [0001] The invention relates to a quality control method, in particular to a method for quality control of Gastrodia elata medicinal material and its decoction pieces and extracts.
