Abstract

The invention relates to a ferulic acid glyceryl oleate polyvinylpyrrolidone nanometer fiber membrane and preparation and application thereof. The preparation comprises the following steps of: (1) adding polyvinylpyrrolidone into a solvent, adding ferulic acid glyceryl oleate with stirring, continuously stirring until solution becomes clear and performing ultrasonic degassing for 15 minutes by using an ultrasonic processor to prepare spinning solution; and (2) guiding the spinning solution into an injector, performing high-pressure electrostatic spinning under the conditions of flow rate of 0.8 to 1ml/h, distance between a receiving plate and a spinneret of 10 to 15cm, voltage of 10 to 15kV, ambient temperature of between 20 and 40 DEG C and ambient humidity of 50 to 75 percent by using a flattened needle as a capillary for injecting trickles, and performing vacuum drying for 24 hours at normal temperature to obtain the nanometer fiber membrane. The method is simple and easy to control; nano-fibers are prepared in a high-voltage electric field in one step; and the prepared fiber membrane can be used as an additive in medicine and health, food processing and daily cosmetics industries.

Description

technical field [0001] The invention belongs to the field of instant nanofiber membranes, in particular to a ferulic acid oleic acid glyceryl polyvinylpyrrolidone nanofiber membrane and its preparation and application. Background technique [0002] Ferulic acid (4-hydroxy-3-methoxycinnamic acid, Ferulic acid, FA) is a natural antioxidant widely present in higher plants. It is mainly cross-linked with polysaccharides and lignin to form part of the cell wall. At the same time, it is also one of the important active ingredients of traditional Chinese medicines such as Ferulicum, Angelica, Chuanxiong, and Cimicifuga. A large number of studies have shown that ferulic acid has antioxidant properties and various physiological activities, so it is widely used in the fields of medicine, food and cosmetics. However, the ferulic acid molecule contains double bonds, and the alkane group is relatively short, so it is difficult to penetrate the lipid molecular layer of the biomembrane, a...
