Abstract

The invention relates to a medicinal material detection method and concretely relates to a method for detecting alkaloid content and pesticide residue content of a pinellia ternate medicinal material. The method comprises alkaloid content determination: by chloroform, extracting a sample to be detected so that the extract is obtained and is used as a sample solution, preparing a contrast solution from ephedrine hydrochloride, determining a light absorption value by ultraviolet analysis and carrying out comparison calculation, and pesticide residue content determination: preparing a contrast solution based on acetonitrile protection, preparing a sample solution by acetone ultrasonic treatment, GPC gel penetration chromatogram purification and cyclohexane-ethyl acetate elution, determining content of a plurality of pesticide residues in the pinellia ternate medicinal material by a gas chromatography-mass spectrometry combined method and carrying out concentration calculation. The method provided by the invention solves the technical problem of operation complexity and limitation of the traditional physicochemical property discriminating method, has high accuracy, can be operated simply, has a low cost and has a good application prospect and economic benefits.

Description

technical field [0001] The invention belongs to the field of quality detection of Chinese medicinal materials, and in particular relates to a quality detection method of Pinellia medicinal materials. Background technique [0002] Pinellia medicinal material is derived from the dry tuber of Pinellia araceae plant, which is spherical in shape, some are slightly skewed and a few are long-term spherical, with a diameter of 1-1.5cm; the surface is white or light yellow. There are sunken stem scars on the top, densely dotted root scars around; blunt, smoother bottom; solid texture, white cross-section, rich powder, powder smells pungent to the nose; slight smell, spicy, tongue-numbing and throat-piercing. Pinellia has the effects of drying dampness and resolving phlegm, reducing adverse reactions and relieving vomiting, and dispelling lumps and resolving stagnation. It is mainly used to treat wet phlegm and cold drinks, vomiting, nausea, coughing with excessive phlegm, fullness o...
