Description
Technical field
A kind of preparation method of flavone aglycone micro capsule the present invention relates to the microcapsule preparing technical field.
Background technology
Flavone aglycone generally has two or three hydroxyls and aromatic rings, and promptly two phenyl ring form hexa-atomic or five yuan of oxa-rings by 3 carbon atom be combined intos.This structure is relatively stable, is easy to by cell membrane, and is beneficial to and receptor protein and enzyme combination, and the mother nucleus structure of flavone aglycone is as (I).Flavone aglycone easily combines with sugared aglucon and forms glucosides type flavone compound, and as ginkgetin, soybean isoflavone etc., its structure is as (II).
Flavone compound has only after the glucosidase of intestinal microbial population decomposes usually there not to be active glucosides combining form to exist, and forms just biologically active of flavone aglycone.The glucosides type flavone compound that is decomposed by intestinal microbial population is not difficult for being absorbed, and directly goes into intestinal from bile secretion and excretes.Exist as soybean isoflavone main form in Semen sojae atricolor, and soybean isoflavone is to carry out with the form of soybean isoflavones aglycon (aglycon) in absorption by human body and metabolism, so soybean isoflavones aglycon has the title of " active soybean isoflavone " again with glucosides.Glucosides type flavone compound is under the effect of acid, alkali, enzyme etc., and the O-glycosides key that connects flavone aglycone and sugared aglucon is easy to fracture, thereby obtains flavone aglycone.
Many researchs have shown that flavone aglycone has multiple biological activity, and it is antibiotic except that utilizing, the effects such as antiinflammatory, mutation, blood pressure lowering, heat-clearing and toxic substances removing, calmness, diuresis, in antioxidation, anticancer, anti-cancer, suppress aspect such as lipase remarkable result is also arranged.They are scavengers of most of oxygen-derived free radicals, thereby the vigor of energy increased SOD (superoxide dismutase), reduce the generation of MDA (lipid peroxide malonaldehyde) and OX-LDL (OxLDL ELISA).For example, Quercetin and isoquercitin removing superoxide anion and hydroxy radical effect are better than the free radical scavenger tocopherol of standard; The MDA that hyperin can suppress in cardiac-cerebral ischemia and the erythrocyte autoxidation process produces, significantly improve the activity of SOD and GSH-Px antioxidases such as (glutathion peroxidase) in rat plasma, the cerebral tissue, can directly suppress the formation of oxygen-derived free radicals in the cerebral ischemia process by ESR (electron spin resonance) technology proof hyperin.
Flavone aglycone can also increase coronary flow, and experimental myocardial infarction is had antagonism; Acute myocardial ischemia there is protective effect; Treatment coronary heart disease, angina pectoris, hypertension etc. there is remarkable result; To reducing diastolic pressure, prevent and treat arrhythmia, cardiovascular diseases and blood circulation promoting and blood stasis dispelling and also play an important role.As the flavone aglycone genistein that from Semen sojae atricolor, extracts, suppress the growth of kinds of tumor cells by multiple mechanism, especially breast carcinoma and carcinoma of prostate, the potentiality that are developed as a kind of natural anti-cancer and anti-cancer medicine are arranged, the antioxidation that genistein is good, blood fat reducing and prevent and treat osteoporotic effect also can become a kind of effective natural drug or health product.
Flavone aglycone has very strong oxidation resistance.Phenolic hydroxyl group in the flavone aglycone and oxygen free radical reaction form stable conjugation semiquinone formula free radical, thereby interrupt free free chain reaction, so the stability of conjugation semiquinone formula free radical and hydroperoxides ROOH becomes positive correlation with antioxidant activity.The power of the antioxidation of flavone aglycone also depends on the activity of hydrogen atom on the phenolic hydroxyl group and the steric hindrance of phenolic hydroxyl group free radical, and steric hindrance is big more, and the transmission speed of phenolic hydroxyl group free radical autoxidation chain reaction is slow more, thereby chain reaction is interrupted and the raising non-oxidizability.Studies show that, based on the Fructus Hippophae flavone of Quercetin, isorhamnetin and ginkgetin antioxidant effect and synthetized oxidation preventive agent BHT (4-methyl-2 to Oleum Hippophae, the 6-DI-tert-butylphenol compounds) suitable, the tea polyphenols that contains 60%～80% catechin derivant, its oxidation resistance is better than BHT, is 2.4 times of BHT.The tea polyphenols peroxide of oil-control effectively forms and the decomposition of polyenoic fatty acid, and the greasy shelf-life is prolonged.The flavone aglycone compounds as the Natural antioxidant substitute BHT and have efficiently, the characteristics of low toxicity, thereby come into one's own day by day.
The general indissoluble of flavone aglycone or water insoluble can be dissolved in organic solvents such as methanol, ethanol, ethyl acetate, ether; Because of majority in its molecule all contains phenolic hydroxyl group, so be soluble in diluted alkaline aqueous solution and organic solvents such as pyridine, Methanamide.When flavone aglycone had hydroxyl to replace, water solublity increased; Hydroxy number is many more, and water solublity is also big more.If hydroxyl is methylated, then water solublity reduces, fat-soluble increase.For example general polyhydroxy flavonoid is insoluble to petroleum ether, can separate with liposoluble substance whereby, but Polymethoxylated derivant but dissolves in petroleum ether.
Phenolic hydroxyl group in the flavone aglycone is owing to have the character that is similar to phenolic compound, is subjected to the effects such as heat effect in oxygen in the air and the food processing process easily, slowly is damaged, thereby loses biological activity such as its antioxidation gradually.Glucide such as flavone aglycone and glucose is in food processing process, under the effect that is subjected to factors such as temperature, pressure, the meeting polymerization reaction take place, produce glucosides type flavone compound again, thereby significantly reduce its biological activity, simultaneously because flavone aglycone easy chelated metal ions in food processing process loses its physiological function.In addition because the dissolution characteristics of flavone aglycone limits it greatly in the Application in Food Industry scope.
For make flavone aglycone can be in food processing extensively, convenient, stably use; must overcome the shortcoming of its poorly water-soluble; simultaneously before flavone aglycone is formally brought into play its physiological activity; must prevent that it is subjected to the chelation of metal ion, prevents the destruction of factor such as heat effect in oxygen in the air and the food processing process; therefore, flavone aglycone being taked the certain protection measure is necessary step extremely.The microcapsule technology of flavone aglycone can satisfy above-mentioned requirements just.
