Abstract
The present invention is process of extracting polyphenols from fresh artichoke stem and leaf including microwave oven pre-treatment. The process includes slicing fresh artichoke stem and leaf material, pre-treating with microwave of 2450 MHz frequency and 300-3000 W for 10-300 sec, lixiviating artichoke polyphenols with solvent for 1-3 times directly or after being stoved, collecting the lixiviated liquid, decompression concentrating to obtain 5-20 % concentration artichoke polyphenol extractum. The process has simplicity, high extraction rate, short extraction period, low cost and other features.
Description
Technical field
The present invention relates to a kind of employing microwave Carlina acaulis stem, blade are carried out pretreatment, to extract the wherein method of polyphenol.
Background technology
Carlina acaulis is called arithoke, chrysanthemum Ji, Cynara scolymus L (Cyhara cardunculus.), Dutch Bulbus Lilii again, for the Compositae Cynara scolymus L (Cyhara cardunculus.) belongs to herbaceos perennial.Originate in the Mediterranean bank, American-European countries's plantation is more, and China introduced a fine variety in the Yunnan cultivation from Italy and Spain first in nineteen nineties, planted the area at present and had expanded ground such as Zhejiang, Beijing, Shanghai, Jiangsu, Shandong to.Contain a large amount of phenolic compounds in Carlina acaulis blade, the stem; as flavonoid, coffee quinine acid; these materials have antioxidation, defying age, function such as anticancer, antibiotic; can reduce content of cholesterol in the blood; prevent lipoprotein oxidation in the blood, increase bile secretion, improve gastrointestinal function; prevent arteriosclerosis, protection cardiovascular and treatment dyspepsia syndrome etc.The method of solvent extraction is adopted in the extraction of plant polyphenol, is the dissolution efficiency of accelerating polyphenol, usually in preprocessing process and leaching process, because polyphenol oxidase, the effect of higher temperature etc. can make polyphenol oxidase for a long time, reduces the polyphenol extraction ratio.Microwave is even fast to the processing heating of plant material, can strengthen extraction efficiency, helps extracting heat-labile material.At present, adopt microwave more to the report that the plant material effective ingredient directly extracts, but the amplification industrialization of the equipment of extraction is difficulty relatively, utilize microwave that fresh Carlina acaulis stem and leaf is carried out pretreatment, reach and destroy the plant cell internal structure, accelerate mass transfer, be beneficial to follow-up polyphenol extraction work, do not appear in the newspapers as yet.
Summary of the invention
It is a kind of simple that the object of the invention is to provide, and preprocess method reaches the purpose of fast, efficiently slightly carrying polyphenol in Carlina acaulis stem, the leaf easily.
Solution of the present invention is:
A kind of employing microwave 2450MHz rapidly and efficiently extracts polyphenols in the Carlina acaulis to the pretreatment of fresh Carlina acaulis blade, it is characterized in that: with fresh Carlina acaulis blade is raw material, and with the blade section, sheet directly is not less than 1cm.Adopt microwave 300w～3000w to handle after 10～300 seconds, the oven dry or directly use 10%～100% solvent (ethanol, methanol, water) that Carlina acaulis blade polyphenol is carried out 1～3 lixiviate, the weight ratio of lixiviate stem and leaf and solvent is 1: 3～1: 10, each extraction time 0.5～2 hour, 50～100 ℃ of temperature, collect and leach liquid, concentrating under reduced pressure obtains the extractum of Carlina acaulis polyphenol 5%～15%.Owing to be rich in moisture in the fresh blade cell, microwave is to the vaporization of moisture Fast Heating, and expansible water vapour destroys cellularity, and the easier quilt of active substance leaches; The polyphenol oxidase enzyme deactivation of inside plants behind the microwave heating reduces the destruction to polyphenol simultaneously.
Advantage of the present invention:
1. to directly extracting after fresh Carlina acaulis stem, the blade pretreatment, can reduce exsiccant intermediate link.
2. the amount of extracting the Carlina acaulis polyphenol will be higher than direct solvent and extract 5%～10%.
3. the extraction efficiency of Carlina acaulis polyphenol will be apparently higher than the usual vehicle method, and extraction time shortens to original 30%～50%.
4. it is simple to extract Carlina acaulis polyphenol microwave method for preprocessing, can utilize existing microwave heating equipment, is convenient to promote.
