[0027]First, collect 500g of immature gardenia green fruit from the beginning of July to the beginning of August, put it into clear water, wash it repeatedly with the hands to remove the remaining dirt on the surface, put it in a juice extractor, and squeeze the juice for 15 minutes to obtain a pulp mixture; Pour the pulp mixture into a 1L beaker, and add rice wine with 1 times the mass of the pulp mixture into the beaker, place it in an ultrasonic oscillator, and vibrate for 1 hour at a frequency of 25KHz and a power of 120W. After the vibration is completed, filter, Remove the filter residue to obtain the filtrate; then put the obtained filtrate into a Soxhlet extractor, extract for 40 minutes, collect the filtrate extract, and move it into a distillation device, heat it in a water bath at 60°C for 35 minutes, and distill and remove the rice wine. Obtain the gardenia green fruit extract; Next, pour the gardenia green fruit extract obtained above into a dialysis bag made of a ...
