Embodiment 1
[0039] Example 1 Preparation and Performance Evaluation of Rapid Mosaic Liquid Substance
[0040] 1. Preparation of liquid creation
[0041] (1) Preparation of the lateral leaf extract
[0042] It is weighted 30g of veletine, placed in a conical bottle, adding 60% ethanol solution 500 mL for 3 hours, and extracts 20 min (ultrasonic frequency 40 kHz) at 60 ° C. 3500R · min after cooling to room temperature -1 15 min centrifuged, the filter residue was subjected to ultrasound extraction, centrifugation, combined filtrate, and sideway extract.
[0043] (2) Adding the preparation of liquid creation of the side cypress extract
[0044] The ethanol 25g, butyl acetate 23g and ethyl acetate 26g are mixed, and the mixture is added to the mixture while stirring the PVA 8g, and the mixture is closed (prevent volatilization) until dissolution;
