Abstract: The invention discloses a method for preparing a water-soluble phytosterol nano-dispersion system with intestinal targeted release function, which comprises the following steps: preparing a phytosterol solution; preparing an ethanol aqueous solution containing pectin; then adding zein to obtain a zein pectin solution; mixing the phytosterol solution and the zein pectin solution by means of ultrasonic treatment to obtain a nanoparticle dispersion liquid; rotavaping the nano-particle dispersion liquid to remove ethanol and water to obtain a zein/pectin loaded phytosterol nano-dispersion system. In this invention, not only an ultrasonic method and an anti-solvent method are adopted, but also a pectin component is added with zein as an entrapping agent, which ensures an effective entrapping of phytosterol by zein while further facilitating to form a more compact interface structure and improving a stability of the nano-dispersion system.

Abstract: The present invention relates to a drug delivery system having a double core-shell structure and, specifically, to a double nano-drug delivery system having an inner core-shell containing a poorly soluble camptothecin compound and a water-soluble camptothecin compound inside and an amphiphilic polymer shell, and to a manufacturing method therefor. The double core-shell structured particles manufactured by the present invention form very stable particles and show a mono-distribution of particles before and after freeze-drying. The particles of the present invention show excellent results compared with existing monolayer micelles in animal efficacy tests and pharmacokinetic tests, and do not use a surfactant causing hypersensitivity, and thus the use of the particles of the present invention can provide a pharmaceutical composition or a drug delivery system platform, which are safe for the human body.
