specific Embodiment

[0022] 1) First, turn on the high-frequency vibration wall-breaking pulverizer and pre-cool it to -40°C;

[0023] 2) Use a high-frequency wall-breaking grinder to crush the honeysuckle wall to 30 microns, and the cell wall-breaking rate of honeysuckle can reach 90%;

[0024] 3) Add 4 times the amount of water, and extract at room temperature for 40 minutes under the action of 30KHz ultrasonic waves;

[0025] 4) Refrigerate and stand for 28 hours, take out the existing oil layer on the surface to obtain part of the crude essential oil, and then filter out the precipitate to obtain an oil-water mixture; in addition, dry the precipitate as a feed additive;

[0026] 5) Use a 3000r / min high-speed centrifuge to separate the oil-water mixture to obtain honeysuckle crude oil and honeysuckle water extract;

[0027] 6) Carry out molecular distillation of honeysuckle crude oil at 80°C to obtain high-quality honeysuckle essential oil;

[0028] 7) Honeysuckle water extract, add HCl to ad...

Abstract

The invention relates to a novel method for simultaneously extracting and separating chlorogenic acid and honeysuckle flower essential oil from honeysuckle flower by wall-breaking ultrasonic extraction separation technology. The method comprises the following steps of: performing wall-breaking treatment by adopting a high-frequency vibration wall-breaking crusher, and performing ultrasonic water extraction filtration; standing and refrigerating filtrate, and centrifugally filtering to obtain an oil-water mixture; centrifuging the oil-water mixture at a high speed again; performing ultrafiltration on a water phase, extracting by using ethyl acetate, and separating, concentrating and drying to obtain high-purity chlorogenic acid; and performing molecular distillation on an oil phase to prepare high-quality honeysuckle flower essential oil. The method furthest ensures the bioactivity and original characteristics of active ingredients, greatly improves the utilization rate of a honeysuckle flower resource and can remarkably save energy and reduce pollution. The honeysuckle flower treated by unique methods such as wall-breaking ultrasonic extraction and the like can be used to simultaneously prepare high-purity and high-quality chlorogenic acid and honeysuckle flower essential oil, which are widely applied to food, medicines, cosmetics and commodities, so that the aim of fully utilizing resources is fulfilled and the method has good economic benefits.

Description

technical field [0001] The invention relates to an extraction process of bioactive components, in particular to a new method for simultaneously extracting and separating chlorogenic acid and honeysuckle essential oil from honeysuckle by using wall-breaking ultrasonic extraction and separation technology. Background technique [0002] Honeysuckle is fragrant and sweet. Its extract, chlorogenic acid, is an important biologically active substance, which has the functions of antibacterial, antiviral, increasing white blood cells, protecting liver and gallbladder, antitumor, lowering blood pressure, lowering blood fat, scavenging free radicals and stimulating the central nervous system. The floral essential oil of honeysuckle is widely used in food, medicine, cosmetics and daily necessities. [0003] The existing technology of extracting chlorogenic acid from honeysuckle mostly uses ethanol for multiple extractions and then purifies chlorogenic acid through various impurity remo...
