Method for extracting effective components from willow buds and application of willow buds

Abstract

The invention relates to a method for extracting effective components from willow buds and an application. The method specifically comprises steps as follows: (1) firstly, fresh willow buds are taken and washed with clear water for 2-3 times and drained; (2) the willow buds are subjected to pressurized high-speed rotary impact and continuous cycle grinding by the aid of a high-speed bead mill, and powder of 5 mu m is obtained; (3) 90% ethanol and methanol with the volume ratio being 9:1 are mixed to form a solvent, extraction is performed with the liquid-solid ratio being 6-10 mL/g at the temperature of 110-115 DEG C and under the pressure of 900-910 KPa for 10-15 min, an extraction solution is obtained, and a concentrated solution is obtained through rotary evaporation; (4) the concentrated solution is subjected to vacuum drying, and the obtained powder is the effective antibacterial components of the fresh willow buds. According to the method for extracting the effective components from the willow buds, multi-factor testing is adopted, the optimal extraction effect is obtained, and the whole method is simple, easy to implement and suitable for large-scale industrial production and provides wide usage space for the application of the willow buds.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a method for extracting active ingredients from willow buds and its application.
