Abstract
The invention relates to the technical field of medicinal mulberry extraction, in particular to a method for producing general flavone of medicinal mulberry by supercritical carbon dioxide extraction. The method comprises the following steps: pulverizing dried medicinal mulberry to granules with a particle size in the range from 10 meshes to 30 meshes by using a pulverizer with good leak tightness, loading the pulverized granules to an extraction tank, placing the extraction tank inside an extraction kettle, sealing the extraction kettle, introducing carbon dioxide in supercritical state to allow extraction, and collecting pale-yellow solid extracts. The production method is easy to operate and repeat, and doesn't need any other organic solvents except carbon dioxide and anhydrous alcohol. The carbon dioxide is colorless, tasteless, innoxious, non-flammable and inert to chemicals and has no environmental pollution; and the anhydrous alcohol evaporates spontaneously in the after-treatment without any residues or toxicity, so that the flavonoid extract has high purity, low impurity content, no heavy metal residue and no toxicity to human body. The method for extracting flavonoid components from medicinal mulberry doesn't cause environmental pollution.
Description
Technical field
The present invention relates to the extracting method technical field of medicine Fructus Mori, is a kind of employing supercritical carbon dioxide process extraction method for producing general flavone of medicinal mulberry.
Background technology
Medicine Fructus Mori (Morusnigra Linn., the medicine Mulberry) on Plant Taxonomy, belongs to Moraceae, Morus plant, be Aksu, Xinjiang and field and Kaxgar Prefecture and the ancient fruit resource of Ba Zhou and gram state, being the medical material among the people of nutraceutical resource, Chinese medicine and the Uygur nationality of preciousness, is unique special rare your resource in Xinjiang.
The medicine Fructus Mori has anti-cancer antimutagenic, enhancing immunity, guarantor's kidney hepatoprotective, the defying age of preserving youthful looks, promotes hematopoietic cell growth and lowering blood sugar and blood fat effect.The nutritional labeling of medicine Fructus Mori is very abundant, and especially content of flavonoids is higher, and a large amount of studies show that, the effect of preventing and curing diseases of medicine Fructus Mori is with wherein to contain abundant flavonoid active component closely related.
Heavy metal is one of important pollutant of Chinese medicine, and the content of heavy metal height has become an important indicator weighing the Chinese crude drug quality good or not in the Chinese crude drug, and toxic heavy metal element is often referred to lead (Pb) in the Chinese medicine, cadmium (Cd), hydrargyrum (Hg), arsenic (As), copper (Cu), chromium (Cr) etc.In recent years, very pay close attention to the content problem of heavy metal element in the Chinese medicine in the world, import Chinese medicine is all had clearly regulation.Therefore, go abroad, participate in the competition of international medical market, reason that the heavy metal element in the tcm product is exceeded standard and research how to control content of beary metal are imperative.
We find in the work in early stage, and the medical value research to the medicine Fructus Mori at present all lays particular emphasis on the clinical practice aspect, still traditional solvent extraction method on the flavonoid extraction of active ingredients, and its flavonoid active component content is low, and content of beary metal is more.
