Abstract
The invention discloses a production technology employing a ultrasonic countercurrent extraction process and a membrane separation (molecular sieve) process to acquire two antioxidants from Rosmarinus officinalis L. The production technology comprises adding 30 to 85% of edible alcohol into fresh rosemary branches and leaves, carrying out a ultrasonic counter current extraction process for a mixture of the edible alcohol and the fresh rosemary branches and leaves to obtain an extracted liquid with a solid-to-liquid ratio of from 1:10 to 1:30, and carrying out a membrane separation (molecular sieve) process to separate two antioxidant agents consisting of a rosemary fat-soluble antioxidant agent (comprising carnosic acid as a representative) and a rosemary water-soluble antioxidant agent (comprising rosmarinic acid as a representative) from the extracted liquid, wherein a heating time of the extracted liquid can be reduced through the membrane separation (molecular sieve) process thus a conversion ratio of rosmarinic acid to carnosol is reduced. A content of carnosic acid in the rosemary fat-soluble antioxidant agent is increased through a CO2 supercritical extraction process. The rosemary water-soluble antioxidant agent (comprising rosmarinic acid as a representative) is separated from a liquid obtained through a concentration process under reduced pressure and a solid-liquid separation process, and a content of rosmarinic acid in the rosemary water-soluble antioxidant agent is increased through recrystallization from ethanol. The production technology has the advantages of simple processes, low energy consumption, high production efficiency, production safety, and no harmful residual solvent due to single edible alcohol usage during all production processes.
Description
Technical field:
The extraction separation that the invention belongs to the high-activity natural antioxidant substance is made the field, and special design separates the production technique that obtains two kinds of antioxidants in the labiate Rosmarinus officinalis.
Background technology:
Rosmarinus officinalis (Rosmarinus officinalis L) is a labiate, be the perennial evergreen undershrub, the country of origin is Europe, north African and Mediterranean Sea bank, and main product state is France, Spain, Yugoslavia and Italy etc., and extensively cultivate various countries, the whole world now.
It is documented that in three state King Wen Wei periods, Rosmarinus officinalis is introduced China from the Western Regions, " the Rosmarinus officinalis tax " of Cao Zhi is exactly good proof.Beijing plant institute of the Chinese Academy of Sciences has successfully introduced a fine variety Rosmarinus officinalis in 1981.This plant requires very low to soil, be suitable for the cultivation of deserted mountain and dead soil, and the bright product of per mu yield can reach more than 1500 kilograms.Because of Rosmarinus officinalis can give out unique fragrance, and have higher ornamental value,, some or soil and slope protection, the desirable kind of controlling soil erosion are arranged wherein so it becomes the common afforestation cultivated plant of Mediterranean Sea coastwise contries.Warm, the sunny airy environment of Rosmarinus officinalis happiness.Anti-morning, winter resistance are good, and general temperature can normally survived the winter more than～10 ℃, intolerant to waterlogging, and the month seedling jaundice fallen leaves of excessive rainfall, well developed root system divides principal stresses strong.
Rosmarinus officinalis effective constituent
1. flavonoid
6 one chrysoeriols, 5-hydroxyl one 7,4 one dimethoxy flavones, 5,4 one dihydroxyl, one 7 one methoxy flavones.
2. terpene
2.1 monoterpene and sesquiterpenoids are the derived essential oil of common aromatising flavour.
2.2 diterpenes: be mainly the diterpene phenolic compound.Diterpenes is oxidation resistant main active ingredient: Rosmarinus officinalis phenol, table Rosmarinus officinalis phenol, carnosol, Rosmarinus officinalis dialdehyde, Salvin, Rosmarinus officinalis diphenol etc.
3. acidic component: rosmarinic acid, ursolic acid, neat big and heavy stone tartaric acid, coffic acid, chlorogenic acid etc.
As far back as twentieth century beginning of the fifties, people such as Chipault study with regard to the anti-oxidant activity of 32 kinds of spices, and Rosmarinus officinalis and Salvia japonica Thunb. are very praised highly.The Rosmarinus plant by many developed countries in the world or area drop into a large amount of financial resources as the economical plant of preciousness, manpower is studied, and has obtained very big achievement.It is documented these researchs comprise fundamental research by the forming of the extraction of Rosmarinus officinalis effective constituent and effective constituent, antioxidation mechanism etc.; Applied research comprises foodstuffs industry, daily-use chemical industry, medicines and health protection etc.Wherein, France, the U.S. and Japan starting drop into maximumly the earliest, and the scope of research mainly concentrates on cultivation technique, cottage propagation, tissue culture fast-propagation and in the comprehensive exploitation utilisation technology of environmental improvement, medicine, aspect such as anticorrosion etc.1980, the investment that the U.S. is used for this intermediate item reaches 5,400 ten thousand dollars, since the eighties, the U.S. and Japan have tentatively finished the extraction process of antioxidant, successively release the Rosmarinus officinalis series product, be widely used in being favourably welcome in American-European market on fried food product, rich oil food, each quasi-grease preservation and medicine, the makeup, just progressively replace the synthetic antioxidant at present.
Synthetic antioxidant butyl hydroxyanisole (BHA), butylated hydroxytoluene (BHT), Tenox PG (PG) and Tert. Butyl Hydroquinone (TBHQ) cause savings to poison to liver and kidney.Present many countries have limited the quantity of or have banned use of synthetic antioxidant to the human body toxic side effect, have banned use of BHA, BHT, TBHQ such as Northern Europe, the use of also having limited the quantity of of the U.S., Japan and the Western European countries.Rosemary antioxidant is in animal-plant oil, rich oil food and meat product, has the effect that prevention and delay are become sour or prolonged preservation period, and the toxic side effect of synthetized oxidation preventive agent and the weakness that heat is decomposed have thoroughly been avoided, the fried test of toxicological experiment and high temperature shows for 240 ℃, safe, efficient, heat-resisting, characteristics such as antioxidant effect is good, wide spectrum that rosemary antioxidant has, LD50 is the 20g/kg body weight.
Modern pharmacological research proves: contained diterpene phenols composition in the Rosmarinus officinalis, have significantly anti-oxidant, antitumor, anti AIDS virus, keep away mosquito and other multiple microbic activity, except that using, be expected to develop antitumor, the anti-AIDS that becomes high-efficiency low-toxicity, keep away medicine such as mosquito as antioxidant.
Rosmarinus officinalis resistance of oxidation have anti-aging effects, the Chinese medicine voluminous dictionary: Rosmarinus officinalis has strong function.Anti-hepatitis and hepatoprotective effect and the ability of relieving the effect of alcohol.Enzyme falls, to fall turbid effect remarkable, the fine selection of treatment fatty liver alcoholic liver, prevention liver cirrhosis.
That rosmarinic acid has is significantly analgesic, analgesia, anti-inflammatory, anti-oxidant, antithrombotic and fibrinolytic activity, and Germany puts on market as analgesic, analgesia, anti-inflammatory drug at present, and is expected exploitation and becomes the antithrombotic new drug.Nineteen eighty-three, European countries just extracted the medicine that drug development goes out to treat varix, hemorrhoid, eczema, psoriasis, psoriatic and skin infections etc. with Rosmarinus officinalis.
Current rosemary antioxidant production technology defective:
The main antioxidant composition of Rosmarinus officinalis is Salvin and rosmarinic acid, Salvin is extremely unstable, endophytic enzyme, temperature, oxygen in the extracting solution etc. all can cause the conversion of Salvin, studies show that: the Rosmarinus officinalis leaf is in drying, distillation, in the crushing process, the content of Salvin descends about 10～20%, from to Salvin in the Rosmarinus officinalis and carnosol mass ratio, bright leaf is 10: 1, shady and cool cured leaf 8: 1, extract 6: 1, the rosemary antioxidant product of some company can reach 1: 1, this explanation Salvin is very easy to transform to carnosol, in addition the rosemary extract of some company with the content of carnosol as product index.
So reduce the conversion of Salvin to carnosol, the content that improves Salvin is exactly advanced part of the present invention.
