Quality detection method of Engelhardia roxburghiana wall dried leaves

Abstract

The invention discloses a quality detection method of Engelhardia roxburghiana wall dried leaves, which comprises the steps of carrying out qualitative analysis on theEngelhardia roxburghiana wall dried leaves by using thin-layer chromatography, forecasting by using the advantages of trace, rapidness and simplicity of the thin-layer chromatography, carrying out quantitative analysis by using high performance liquid chromatography, carrying out quantitative analysis by combining a one-marker multi-evaluation method based on a high performance liquid chromatography technology, taking the astilbin reference substance as a reference, and measuring the contents of six components including astilbin, astilbin, neoisoastilbin, iso-astilbin, quercitrin and engelhardia roxburghiana glycoside in theEngelhardia roxburghiana wall dried leaves at the same time. The cost is low, the time is short, the operation is simple and convenient, and the detection result is relatively accurate. Qualitative analysis and quantitative analysis are carried out on the Engelhardia roxburghiana wall dried leaves through the quality detection method, and a foundation is laid for quality standard establishment of the Engelhardia roxburghiana wall dried leaves.

Description

technical field [0001] The invention relates to the technical field of quality detection of traditional Chinese medicine, in particular to a quality detection method of Luo Han tea. Background technique [0002] Arhat tea is the Juglandaceae plant Huang Qi ( Engelhardia roxburghiana wal1. ) is a strong medicinal material widely used by folks in Guangxi.
