Example Embodiment
[0018] Example 1
[0019] Weigh 400g of the stalks of Longxian stalks and cut them into 3cm pieces. According to the solid-to-liquid ratio of 1:5, immerse the small pieces of longxian stalks in deionized water, and immerse them overnight at 200W with an ultrasonic oscillator. , Remove the soaked stalks, spray and freeze with liquid nitrogen for 1 min, wait for it to naturally return to room temperature, repeat the water soaking and freezing treatments 3 times according to the aforementioned steps, to obtain the mesoporous longhair stalks for use; The stalks of Potentilla serrata were added to 8 times its total mass in anhydrous methanol, placed on a shaker and immersed for 6 hours, filtered and separated to obtain the filter residue, rinsed with deionized water for 3 times and then dried naturally to obtain the pretreatment medium. The stems and stalks of Potentilla serrata, set aside; weigh 1kg of garcinia cambogia peel into an iron pot, add distilled water to the pot until the ...
