Embodiment 1

[0058] Take the white insect wax raw material, pressurize it in the reaction tank at 110° C. and melt it; (2) add 20% NaOH solution of 1.5 times the amount of the raw material; (3) keep the pressure in the reaction tank at 0.1-0.15Mpa and saponify for 6 hours; After the saponified product was washed with water, it was dried at 50°C to obtain the crude product; (4) put the crude product into a continuous extractor, and add No. 6 solvent oil for continuous extraction for 3 hours; (5) recover and concentrate the extract in the concentrator to obtain a concentrated solution, The concentrated solution was cooled to 20°C, and crystals were precipitated; the crystals were obtained by filtration; and the crystals were dried for 3 hours. After drying, the crystals are ball-milled into fine powder and passed through a 90-mesh sieve, and the dry matter is crushed, mixed and packaged.

Embodiment 2

[0060] Take the white insect wax raw material, pressurize it in the reaction tank at 100°C and melt it; (2) add 25% KOH solution of 1 times the amount of the raw material; (3) keep the pressure in the reaction tank at 0.1-0.15Mpa and saponify for 5 hours; After the saponified product was washed with water, it was dried at 40°C to obtain the crude product; (4) put the crude product into a continuous extractor, add petroleum ether for continuous extraction for 2 hours; (5) recover and concentrate the extract in the concentrator to obtain a concentrated solution, and concentrate The liquid was cooled to 15°C, and crystals were precipitated; the crystals were obtained by filtration; the crystals were dried for 2 hours. After drying, the crystals are ball-milled into fine powder and passed through a 60-mesh sieve, and the dry matter is crushed, mixed and packaged.

Embodiment 3

[0062] Take the white insect wax raw material and melt it under pressure at 115°C in the reaction tank; (2) add 20% NaOH solution twice the amount of the raw material; (3) keep the pressure in the reaction tank at 0.1-0.15Mpa for 7 hours for saponification; After the saponified product was washed with water, it was dried at 65°C to obtain the crude product; (4) put the crude product into a continuous extractor, and add No. 6 solvent oil for continuous extraction for 4 hours; (5) recover and concentrate the extract in the concentrator to obtain a concentrated solution, The concentrated solution was cooled to 45°C, and crystals were precipitated; the crystals were obtained by filtration; and the crystals were dried for 4 hours. After drying, the crystals are ball-milled into fine powder and passed through a 120-mesh sieve, and the dry matter is pulverized, mixed and packaged.

Abstract

A process for preparing priol used to prepare medicine or health-care food for improving endurance and decreaisng cholesterol and blood fat includes fusing white insect wax, adding NaOH (or KOH) solution, saponifying, water washing, drying to obtain coarse product, continuous extracting in solvent oil or petroleum ether, concentrating, cooling to educe crystals, filtering and drying.

Description

technical field [0001] The invention relates to an extraction process of high-carbon aliphatic alcohol Policosanol and the application of Policosanol using white insect wax as a raw material. Background technique [0002] Polyol contains C 24 、C 26 、C 28 、C 30 、C 28 A series of high-carbon fatty alcohols, with octacosyl alcohol as the main component. The extraction process of plicohol is currently known to use cane wax, bran wax, and beeswax as raw materials, using a mixed solvent of benzene and isoamyl alcohol, and ethanol as the extraction solvent. When it is applied to industrial production, it has the problems of long process flow, large investment, high energy consumption and high product cost. At present, the main functions of pliol are: (1) improve the sensitivity of response; (3) improve the stress ability; (4) promote the action of sex hormones and relieve muscle pain; (5) improve myocardial function; it can be used to prevent and treat syndrome X, Complicati...
