Problems solved by technology

[0009]Compared with existing patents, such as the extraction and purification method of chlorogenic acid in honeysuckle (01144170), the process method of macroporous resin adsorption and extraction of high-content chlorogenic acid ( 02133448), a process for extracting chlorogenic acid from maple ingots (0314575). These patent application technologies are all water boiling, alcohol precipitation, and resin adsorption processes. They all use only dried honeysuckle flowers, and the extraction rate is not high. The separation purity Poor, chlorogenic acid is oxidized and decomposed during the high temperature extraction process.

Embodiment approach 1

[0028] 1. Harvesting of fresh and live materials: select authentic honeysuckle products without pesticide residues, pests and industrial pollution. The ratio of flowers, fresh leaves and fresh vines is: 1:2:3. The storage time after harvesting should not exceed 12 hours, and the natural cleanliness should be maintained during harvesting, transportation and storage.

[0029] 2. Beating of fresh and living materials: Use a stainless steel beater with a fineness of 0-5 mesh, and the storage time of the slurry should not exceed 30 minutes, or be preserved at 0-5°C.

[0030] 3. Alcohol precipitation: add 3-5 times of ethanol with a content of 75-95% according to the weight of the honeysuckle fresh material after beating, and extract for 5-7 days.

[0031] 4. Alcohol precipitation liquid membrane separation: ①coarse filtration: the filtration accuracy is 100 mesh, its function is to remove large particles and impurities in the liquid, and ensure the normal operation of subsequent p...

Embodiment 2

[0036] As described in Example 1, the difference is that the obtained chlorogenic acid is extracted once more after the supercritical fluid CO2 extraction, and the obtained chlorogenic acid has a purity of ≥60%.

Embodiment 3

[0038] As described in Example 2, the difference is that the obtained chlorogenic acid is extracted for the second time by supercritical fluid, and then extracted for the third time, and the purity of the obtained chlorogenic acid is ≥70%.

Abstract

By using fresh flower, fresh leaf and fresh vine of honeysuckle as material and through the advanced technological process including pulping, alcohol precipitation, membrane separation and supercritical CO2 fluid extraction, honeysuckle chlorogenic acid as the active matter in honeysuckle and total honeysuckle flavone as the side product are extracted. The products coincides with the relevant standard and are used as the additive for daily chemical product and health food.

Description

technical field [0001] The invention relates to a technology for extracting standard chlorogenic acid by using honeysuckle flowers, fresh leaves and fresh vines and advanced technology. Background technique [0002] Honeysuckle is the dried buds or the first flowers of Lonicera japonica Thunb, Lonicera hypoglaula Miq, Lonicera confusa Dc, or Lonicera japonica Rehd. Honeysuckle is a medicine and a dual-purpose plant. [0003] Flos Lonicerae is sweet in nature, cold, returns lung, heart, stomach diameter. Functions and Indications Clearing away heat and detoxification, dispelling wind-heat. For pain and swelling furuncle, sore throat, erysipelas, pyretic toxin blood dysentery, wind-heat cold, fever due to febrile disease. It is also clinically used in the prevention and treatment of tumors and SARS. [0004] The main medicinal ingredient of honeysuckle is chlorogenic acid, chlorogenic acid chlorogehli acid, its molecular formula and molecular weight C 16 h 18 o 9 354.3...
