Embodiment 1
[0022] Embodiment 1, extraction process
[0023]Grind 100g of melon stems into coarse powder, pass through a 10-mesh sieve, add 1000g of 80% ethanol for extraction, 2 hours / time, extract twice, combine the extracts, filter, dry to 800ml, filter, add ethanol or water to adjust to The concentration of ethanol is 50-60%, and it is made into 1000ml, and the crude product is obtained by filling and sterilizing. Put the crude product on a silica gel column, use petroleum ether solution, chloroform solution, a mixed solution of chloroform and ethyl acetate with a volume ratio of 1:1, a mixed solution of chloroform and ethyl acetate with a volume ratio of 1:3, ethyl acetate, and 95% ethanol , and water was used as the mobile phase for fractional elution, and each fraction was collected and dried. Obtain water part elution phase, chloroform elution phase part, alcohol elution phase part, ethyl acetate elution phase part, chloroform: ethyl acetate 1: 1 elution phase part and chloroform...

[0025] Experimental Example 1, Extraction of Melon Pedicel Components
[0026] Grind 100g of melon stems into coarse powder, pass through a 10-mesh sieve, add 1000g of 80% ethanol to extract twice, 2 hours each time, extract twice, combine the extracts, filter, dry to 800ml, filter, add ethanol or water Adjust the ethanol concentration to 50-60%, make 1000ml, fill and sterilize to obtain the crude product. Put the crude product on a silica gel column, use petroleum ether solution, chloroform solution, a mixed solution of chloroform and ethyl acetate with a volume ratio of 1:1, a mixed solution of chloroform and ethyl acetate with a volume ratio of 1:3, and ethyl acetate solution, 95% Ethanol solution and water were used as the mobile phase for fractional elution, and the fractions were collected and dried. The water elution phase, chloroform elution phase, alcohol elution phase, ethyl acetate elution phase, chloroform:ethyl acetate 1:1 elution phase and chloroform:ethyl aceta...
experiment example 2
[0027] Experimental Example 2, Screening of Purging Active Elution Phase
[0028] 70 mice were taken, half male and half female, weighing 18-22 g, numbered, weighed, sorted by weight, randomly divided into 7 groups with 10 mice in each group. During the experiment, the first group was given distilled water by intragastric administration, and the second to seventh groups were given water elution phase, alcohol elution phase, ethyl acetate elution phase, chloroform elution phase, chloroform:ethyl acetate 1:1 Elution phase, chloroform: ethyl acetate 1:3 elution phase; after 30 min, each group was given 0.2 ml of ink by intragastric administration, and then the mice were individually placed in a cage lined with filter paper, and the filter paper was changed every 1 h. Continuously observe for 6 hours, record the time when the mice first appeared ink-containing feces, the time for the first loose stool, the number of black stools, loose stools and total stools discharged by the mic...
