Abstract

The invention provides a solid self-microemulsion microcapsule containing astaxanthin and quercetin, a preparation method and application thereof. The self-microemulsion microcapsule comprises astaxanthin, quercetin, an oil phase, an emulsifier, a co-emulsifier and a solid adsorbent. According to the invention, starting from the design angle of a drug-loaded delivery system, astaxanthin and quercetin are combined to prepare a solid self-microemulsion microcapsule system, so that the traditional single carrying system of astaxanthin is broken through; the quercetin has high safety, and can inhibit the excretion effect of P-gp on medicine, so that the activity of drug metabolic enzyme CYP3A4 and drug transporter P-glycoprotein is inhibited, the bioavailability is improved, the solubility ofthe astaxanthin is improved, the quercetin and the astaxanthin can be compounded to play a role, the stability can be improved, and the oxidation resistance of the astaxanthin is not influenced; and the solid self-microemulsion microcapsule has the advantages of liquid self-microemulsion and a solid preparation, so that the dissolution rate and the bioavailability of the medicine are improved.

Description

technical field [0001] The invention belongs to the technical field of carrier systems in functional foods, and specifically relates to a solid self-microemulsion microcapsule containing astaxanthin and quercetin, a preparation method and application thereof. Background technique [0002] Astaxanthin is currently the strongest antioxidant. Recent studies have shown that astaxanthin can prevent and treat cardiovascular diseases, lower blood pressure, prevent and treat atherosclerosis, protect the nervous system, relieve inflammation, prevent and treat cancer, and treat liver diseases. It has various pharmacological activities, such as injury reduction, obesity reduction, prevention and treatment of diabetes, skin protection, vision protection, sports injury reduction and immunity enhancement. Astaxanthin is also the only carotenoid found so far that can penetrate the blood-brain and blood-retinal barriers, and can have a positive impact on the central nervous system and brain...
