Abstract

The invention discloses a method for determining the content of nitidine chloride in radix zanthoxyli toothpaste, and belongs to the field of chemical detection. The method is accurate, simple and convenient and can be used for controlling the content of nitidine chloride in the radix zanthoxyli toothpaste. The method comprises the following sub-steps sequentially: firstly, extracting nitidine chloride from radix zanthoxyli with ethanol, and collecting ethanol extract; secondly, determining the content of nitidine chloride in the ethanol extract with HPLC (high performance liquid chromatography). The method can be used for determining the content of nitidine chloride in the radix zanthoxyli toothpaste.

Description

technical field [0001] The invention belongs to the field of chemical detection, in particular to a method for measuring the content of lianthine chloride in liangmianzhen toothpaste. Background technique [0002] ZanthorμLumnitidum (Roxb.) DC. Bitter, pungent, neutral in nature, slightly toxic, returns to Liver and Stomach Meridians. It has the effects of promoting qi and relieving pain, promoting blood circulation and removing blood stasis, dispelling wind and dredging collaterals, and is used for bruises, rheumatic arthralgia, stomach pain, and toothache caused by qi stagnation and blood stasis. The main active ingredient of LMZ is LMZ chloride, and now LMZ is also widely used in Chinese patent medicines, such as Fufang Fengshining Capsules and Fuyanjing Tablets. Clinical trials have shown that adding double-sided needles to toothpaste can relieve toothache, relieve inflammation, reduce dental plaque and gingivitis, and help prevent gum bleeding and gum recession and ot...
