Abstract

The invention relates to a rapid microwave moisture measurement method for a fluid extract and an extract. The method comprises the following steps: 1, taking two pieces of glass fiber papers, putting the glass fiber papers on a balance of a microwave moisture measurement apparatus and weighing in a peeling manner, taking an extract sample and putting the extract sample on one piece of glass fiber paper, covering with the other piece of glass fiber paper and flattening, then putting the papers back to the balance, covering with a detection pool, beginning to detect and recording a measurement value; 2, substituting the measurement value of the microwave moisture measurement apparatus into a data model, and calculating the moisture value according to the formula that the moisture value of the extract is equal to X * the measurement value of the microwave moisture measurement apparatus + Y, wherein X and Y are relationship parameters of moisture measurement by microwaves and moisture measurement by a drying method.

Description

Technical field: [0001] The invention relates to a moisture determination method in traditional Chinese medicine extracts, in particular to a rapid microwave moisture determination method for liquid extracts and extracts. Background technique: [0002] Traditional Chinese medicine formulations are currently roughly divided into three categories: extracts, extracts + crude drug powders, and crude drug powder preparations. Traditional Chinese medicine extract preparation is the main form of modern Chinese medicine preparation. This preparation can not only ensure all the active ingredients in the decoction, but also meet the requirements of traditional Chinese medicine solid preparation, so it is a commonly used dosage form. However, the solid preparations of traditional Chinese medicine extracts made by extraction and separation all have different degrees of moisture absorption, resulting in softening of traditional Chinese medicine preparations after absorbing moisture, dark...
