Examples
Embodiment 1
[0017] Embodiment 1: Fructus Trichosanthes water extract extracts (comparative example)
[0018] Take 1000g of dried melon skin, pulverize, sieve, put in the extraction device and add 6L of water, extract for 24 hours, filter and centrifuge to obtain the extract, the extract is freeze-dried to obtain a solid extract, low temperature (4°C) Save for later.
Embodiment 2
[0019] Embodiment 2: Trichosanthes quince ethyl acetate extract extract
[0020] Take 1000g of dried melon skin, crush and sieve, add 4L (single dose) of petroleum ether to degrease 3 times, 5 hours each time, temperature 30-40°C, filter, evaporate the filter residue to dry petroleum ether, add 5L (single dose) times) of ethyl acetate at room temperature and extracted 3 times at room temperature for 24 hours each time. The extracts were combined, concentrated under reduced pressure, and freeze-dried to obtain the ethyl acetate extract of Trichosanthes melaka, which was stored at 4°C for future use.
Embodiment 3
[0021] Embodiment 3: the preparation of trichosanthes petroleum ether extract
[0022] Take 1000g of dried melon skin, pulverize and sieve, add 4L (single dose) of petroleum ether to degrease 3 times, each time for 5 hours, at a temperature of 50-60°C, filter, evaporate the filter residue to dry petroleum ether, add 5L (single dose) Subsequent use) of methanol heating and reflux extraction 3 times, 2 hours each time, combined extracts, concentrated under reduced pressure until the volume is 1 / 5 of the original volume, then extracted with petroleum ether, concentrated under reduced pressure, freeze-dried, that is Trichosanthes petroleum ether extract, stored at 4°C for later use.
