Embodiment 1

[0022] A. Add 100g of peanut shells washed with water to 1000mL of petroleum ether, and degrease at 60°C for 4hr;

[0023] B. Add 1500mL of the above-mentioned treated peanut shells that have been drained, and desugar at 80°C for 3hr;

[0024] C. Add 1000mL of 80% ethanol aqueous solution to the above-mentioned treated peanut shells that have been drained, and extract at 80°C for 1.5hr;

[0025] D. Concentrate the alcohol-water extract until 1 / 3 of its volume is left, and then spray-dry it to obtain peanut shell extract particles with a yield of 1.2%. Quantitatively analyze luteolin in it by HPLC, and the content can reach 8.9%.

Embodiment 2

[0027] A. Add 100g of peanut shells washed with water to 2000mL of petroleum ether, and degrease at 70°C for 2hr;

[0028] B. Add 2000mL of the above-mentioned treated peanut shells that have been drained, and desugar at 100°C for 1hr;

[0029] C. Add 3000mL of 60% ethanol aqueous solution to the above-mentioned treated peanut shells that have been drained, and extract at 70°C for 5hr;

[0030] D. Concentrate the alcohol-water extract until 1 / 3 of its volume is left, then spray-dry it to obtain peanut shell extract granules with a yield of 1.1%. Quantitatively analyze luteolin in it by HPLC, and the content can reach 8.0%.

Embodiment 3

[0032] A. Add 100g of peanut shells washed with water to 500mL of petroleum ether, and degrease at 40°C for 2hr;

[0033] B. Add 2000mL of the above-mentioned treated peanut shells that have been drained, and desugar at 80°C for 6hr;

[0034] E. Add 2000 mL of 70% ethanol aqueous solution to the above-mentioned treated peanut shells that have been drained, and extract at 80 ° C for 1.5 hr;

[0035] F. Concentrate the alcohol-water extract until 1 / 3 of its volume is left, then spray-dry it to obtain peanut shell extract particles with a yield of 1.0%. Quantitatively analyze luteolin in it by HPLC, and the content can reach 7.6%.

Abstract

The invention provides a method for preparing peanut shell extract particles. The method comprises the steps that degreasing is carried out by using petroleum ether, desugaring is carried out by usingwater, alcohol extraction is carried out, and spray drying is carried out to obtain the extract particles. According to the method, the peanut shell extract particles with high content of effective components can be prepared conveniently. The invention belongs to the field of extraction of effective components of natural compounds and granulation of traditional Chinese medicine formula granules.The method for preparing the peanut shell extract particles has the advantage that degreasing and desugaring steps are added to obtain the particles with the high effective components.

Description

technical field [0001] The invention relates to a method for obtaining extract particles from peanut shells, degreasing with petroleum ether, desugaring with water, further ethanol extraction, and spray drying. It belongs to the fields of extraction of active ingredients of natural compounds and granulation of traditional Chinese medicine formula granules. Background technique [0002] Peanut shell is the dried pod shell of legume groundnut. It is a kind of Chinese herbal medicine in the folk. It is light in taste, astringent and flat. Function cures mainly astringing lung and relieving cough. For the treatment of asthma, phlegm, high blood pressure, etc. It is the main ingredient of Maishu Capsules. [0003] Peanut shells have a wide range of sources. Peanuts, which are the second largest source of edible vegetable oil and protein in my country, have been widely planted in the north. Peanut shells are often used as waste, or as feed or fuel, resulting in a great waste of...
