specific Embodiment approach 1

[0012] Specific embodiment 1: The method of extracting non-alkaloids from Chuanzi and Corydalis is carried out according to the following steps:

[0013] 1. Mix 100g of Corydalis and 200g of Neem, then pulverize into a powder of 20-40 mesh, add 3-5 times the total mass of Corydalis and Neem in ethanol to obtain the mixture;

[0014] 2. The mixture obtained in ultrasonic treatment step 1 is 10-20 minutes, the temperature is controlled at 20-40℃, the ultrasonic power is 100-200W, the ultrasonic frequency is 40KHz; then it is transferred to a microwave reactor and heated for 10-20 minutes with microwave power The frequency is 260-520W, the frequency is 2450MHz; then the ultrasonic treatment is 10-20 minutes under the conditions of 20-40℃, ultrasonic power of 100-200W, and ultrasonic frequency of 40KHz, filter, collect the filtrate, distill the ethanol in the filtrate, and then Add water to 200mL, add hydrochloric acid to adjust the pH of the solution to 1-2, and then pass through the ...

specific Embodiment approach 2

[0016] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the volume fraction of the ethanol aqueous solution in step 1 is 60-80%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0017] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the amount of ethanol aqueous solution added in step one is 4 times the total mass of Corydalis and Chuanzi. Others are the same as the first or second embodiment.

Abstract

The invention discloses a method of extracting non-alkaloid from fructus meliae toosendan and rhizoma corydalis, relates to an extraction method of the non-alkaloid and aims at solving the technical problems of the traditional method of extracting the non-alkaloid of low speed, high cost, need for reflux high temperature, complex operation, high cost of extraction process and low extraction efficiency. The method comprises the following steps: mixing the rhizoma corydalis and the fructus meliae toosendan, grinding, adding an ethanol aqueous solution, and carrying out ultrasonic treatment and microwave heating; then carrying out ultrasonic treatment, filtering, collecting a filtrate, steaming out ethanol in the filtrate, adding water to regulate a pH value, and collecting an ion exchange liquid containing the non-alkaloid component; and regulating a pH value to be 7, carrying out vacuum concentration, and drying under vacuum to prepare non-alkaloid powder. Compared with the decocting and alcohol precipitation processes, the method has the following characteristics of rapidness in extraction, high extraction rate, low cost, high efficiency, no need for reflux high temperature, simpleness and feasibility in operation, low cost of the extraction process and remarkable comprehensive economical benefit. The invention belongs to the field of extracting the non-alkaloid.

Description

Technical field [0001] The invention relates to a method for extracting non-alkaloids. Background technique [0002] Jinlingzisan is a famous prescription for treating various pains in the stomach and stomach, it has better curative effect and is safe to use. Chuanmeizi and Yanhusuo are the main two medicines of Chinese medicine Jinlingzisan. Studies have shown that the non-alkaloid components extracted from Jinlingzi powder play a major role in the treatment of gastric ulcers. The usual method of extracting non-alkaloids is water decocting, followed by ethanol extraction. This method is complicated in operation, time-consuming, low extraction efficiency, and low extraction rate of non-alkaloids, which is not conducive to the modern research and application of active ingredients of traditional Chinese medicine. Ultrasonic and microwave assisted extraction of chemical components in traditional Chinese medicine is considered an efficient method. However, the extraction of non-alk...
