Prinsepia utilis royle fruit extract, preparation method and applications thereof

Abstract

The invention relates to the technical field of plant extracts, and discloses a prinsepia utilis royle fruit extract, a preparation method and applications thereof. The preparation method comprises: adding water or ethanol to a prinsepia utilis royle fruit, and extracting to obtain a prinsepia utilis royle fruit crude extraction liquid; and concentrating the prinsepia utilis royle fruit crude extraction liquid, loading the concentrated prinsepia utilis royle fruit crude extraction liquid onto a macroporous adsorption resin, carrying out elution sequentially with deionized water, a 30% ethanol solution, a 70% ethanol solution and a 95% ethanol solution, respectively collecting various elution fractions, and carrying out pressure reducing distillation to remove the solvent so as to correspondingly obtain the prinsepia utilis royle fruit water elution fraction, the 30% ethanol solution elution fraction, the 70% ethanol solution elution fraction, and the 95% ethanol solution elution fraction. According to the present invention, the prinsepia utilis royle fruit non-oil extract is obtained by using the prinsepia utilis royle fruit as the raw material through the appropriate method; and the extracted prinsepia utilis royle fruit extract has remarkable free radical scavenging activity and human fibroblast proliferation promotion effect, and can be used for skin aging-resistance and related cosmetics.
