Abstract

Baicalin is a kind of flavonoids, which has anti-inflammatory, antibacterial, antiviral, and other pharmacological effects, but it has poor water solubility and low bioavailability. To improve the water solubility of baicalin, a casein micelle/poly (lactic acid) composite fiber membrane loaded with baicalin was prepared by electrospinning technology. The microstructure, hydrophobicity, solubility, and in vitro release of baicalin were studied. Results showed that baicalin had little effect on the microstructure of the fibers. With the increase in the ratio of casein micelles, the fiber diameter decreased and the fiber-forming performance decreased. When the mass ratio of casein micelles to poly (lactic acid) reached 2∶1, the fiber diameter was the smallest and the fiber-forming ability was better. The results of infrared spectroscopy and X-ray diffraction showed that baicalin was encapsulated in the fibers. Moreover, casein micelles improved the swelling and degradation rate of poly (lactic acid) fiber membranes. With the increase of casein micelles, the hydrophilicity and degradation rate of the membrane were enhanced, and the swelling rate and swelling time were reduced. In vitro release results showed that the casein micelle-poly (lactic acid) fiber membrane had a good controlled release effect on baicalin. The results can provide a reference for the load of baicalin.
