Abstract
The invention discloses a preparation method of pomegranate leaf tannin, which belongs to the traditional Chinese medicine field. The invention provides the preparation method of the pomegranate leaf tannin, which is efficient and simple to operate. The preparation method comprises the following steps of: cleaning and drying pomegranate leaves; crushing the pomegranate leaves into powder by a crusher, enabling the powder of the pomegranate leaves to pass a 40-mesh sieve; carrying out auxiliary extraction through ultrasonic waves by using 70% of acetone as an extracting solvent, wherein the feed-liquid ratio is (1:10)-(1:40), the ultrasonic wave powder is 60W-100W, the extracting temperature is 30 DEG C-50 DEG C, and the extracting time is 30 minutes-50 minutes.
Description
Technical field
The invention belongs to the field of Chinese medicines, more particularly, relate to a kind of preparation method of Folium Granati tannin.
Background technology
Contain abundant bioactive substance in the Folium Granati, comprise polyphenol, flavone and alkaloid etc., especially the content with polyphenol is the highest, and then take tannin as main component, the tannin composition of having identified has kind more than 20 in the middle of the polyphenol, belong to elladitannin and Galla Turcica (Galla Helepensis) tannin, there are some researches show that tannin has multiple function, energy and metal ion-chelant, and can react with free radical, thereby show very strong oxidation resistance, also have antibiotic, antiviral activity and anti-tumor activity.Extract tannin method commonly used and water extraction and organic solvent extraction are arranged, the organic solvent of use such as ethanol, methanol and acetone etc.; The mode of processing adopts decocting to boil or heating in water bath more.Yet these methods are many, the consuming time length of operation mostly, and extraction ratio is low.
Summary of the invention
The present invention is exactly for the problems referred to above, and a kind of preparation method of Folium Granati tannin efficient, easy and simple to handle is provided.
In order to realize above-mentioned purpose of the present invention, preparation process of the present invention is: Folium Granati is cleaned, dried, then be ground into powder with pulverizer, the powder of Folium Granati is crossed 40 mesh sieves, then with 70% acetone as extracting solvent, carry out assisted extraction with ultrasound wave, solid-liquid ratio is 1:10～1:40, ultrasonic power is 60～100W, and extracting temperature is 30～50 ℃, and extraction time is 30～50min.
Beneficial effect of the present invention.
1. the present invention extracts with heating in water bath and compares, and the ultrasound wave assisted extraction does not need high temperature, and extraction time is short, efficient is high, is convenient to large-scale industrial production.
2. the present invention has very high extraction ratio, has reached 94.63%.
The specific embodiment
Preparation process of the present invention is: Folium Granati is cleaned, dried, then be ground into powder with pulverizer, the powder of Folium Granati is crossed 40 mesh sieves, then with 70% acetone as extracting solvent, carry out assisted extraction with ultrasound wave, solid-liquid ratio is 1:10～1:40, and ultrasonic power is 60～100W, extracting temperature is 30～50 ℃, and extraction time is 30～50min.
The present invention is with solid-liquid ratio, solvent strength, ultrasonic power, treatment temperature and the processing time influence factor as the extraction ratio of Folium Granati tannin.
As a kind of preferred version, technological parameter is: solid-liquid ratio is 1: 20(g/mL), ultrasonic power 100 W, extracting temperature is 40 ℃, and extraction time is 50 min, and the extracted amount under the optimal conditions is 225.12 mg/g, and extraction ratio is 94.63%.
