Preparation method of rhizoma paridis extract

Abstract

The invention discloses a preparation method of a rhizoma paridis extract, and relates to the technical field of rhizoma paridis extraction. The preparation method of the rhizoma paridis extract comprises the following steps: carrying out mixing and infiltrating, specifically, uniformly mixing rhizoma paridis powder with a solvent according to a weight ratio of 1: (9-15) to obtain a mixed solution; carrying out reflux extraction, specifically, performing reflux extraction on the mixed solution for 1.5-2.5 h, carrying out filtering to obtain filter residues A and a filtrate A, mixing the filter residues A with the solvent, performing reflux extraction for 0.8-1.2 h, and carrying out filtering to obtain a filtrate B; and carrying out concentration preparation, specifically, combining the filtrate A and the filtrate B to obtain a combined solution, and concentrating the combined solution to obtain the rhizoma paridis extract. By the method, the extraction steps are reduced by controlling the weight ratio of the rhizoma paridis powder to ethanol, the loss caused by multiple filtration, elution and other steps can be reduced, the yield of the rhizoma paridis extract is improved, moreover, extraction steps are less, reaction conditions are mild, operability is high, and industrial preparation of the rhizoma paridis extract is facilitated.

Description

technical field [0001] The present invention relates to the field of the extracting technology of Chonglou, in particular to a preparation method of the extract of Chonglou. Background technique [0002] Chonglou is a precious Chinese medicinal material, which is the dried rhizome of Yunnan Chonglou or Aescin. Chonglou is bitter in taste, slightly cold in nature, and slightly poisonous. After years of development, Zhonglou is not only used in medicine, but also in many health care products. Generally, the extract of Chonglou is added to health care products, which can improve the health care effect of health care products. [0003] Before preparing health care products with Chong Facility, it is necessary to select a suitable preparation method to prepare the Chong Facility extract. In the related technology, after fermenting the inoculated strains of the polyphylla for a period of time, the water is filtered and sterilized, and the microwave heating and reflux extraction...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in the above preparation method, the polyphylla extract can be prepared through multiple steps such as fermentation, reflux extraction, filtration, decolorization and degreasing, concentration and precipitation, elution, separation and crystallization. substances, it is easy to cause too much loss of the extract of the plant, which is not conducive to improving the yield of the extract of the plant
