Embodiment 1

[0019] A preparation method of durian shell extract, comprising the following steps:

[0020] (1) Take the white capsule endothelium in the durian peel, clean it, chop it into pieces, put it into a drying oven at 100° C., and dry it to constant weight;

[0021] (2) After adding the dried white sac endothelial sheet into a pulverizer to pulverize, pass through a 300-mesh sieve to prepare powder;

[0022] (3) adding the powder prepared by step (2) into the 80% ethanol extractant with a solid-liquid ratio of 1:50;

[0023] (4) refluxing extraction on a constant temperature water bath, refluxing 3 times, each time refluxing for 30 minutes;

[0024] (5) Filtrate with a Buchner funnel under reduced pressure, combine the filtrates, concentrate with a rotary evaporator, and dry to obtain the durian shell extract.

Embodiment 2

[0026] A study on the anti-inflammatory effect of durian shell extract-croton oil-induced mouse ear swelling experiment.

[0027] Get 50 mice and divide them into 5 groups at random, 10 in each group, i.e. normal control group (distilled water 10mg.kg -1 ), positive drug control group (dexamethasone, 1mg.kg -1 ), extract low dose group (100mg.kg -1 ), the extract medium dose group (300mg.kg -1 ), extract high dose group (900mg.kg -1 ). Animals in each group were administered intragastrically once a day for 5 consecutive days, and 1 hour after the last administration, 3 g.L -1 An appropriate amount of croton oil acetone solution was evenly applied to the central part of the right ear margin of the mice to cause ear inflammation in the mice. 30 minutes after the inflammation was induced, the drug was administered once again, and the mice were killed by breaking the cervical spine 4 hours later, and the two ears were cut off, and round ear pieces were punched at the same pos...

Embodiment 3

[0032] A study on the antitussive effect of durian husk extract—a cough test in mice induced by ammonia water.

[0033] Get 50 mice and divide them into 5 groups at random, 10 in each group, i.e. normal control group (distilled water 10mg.kg -1 ), positive drug control group (codeine, 20mg.kg -1 ), extract low dose group (100mg.kg -1 ), the extract medium dose group (300mg.kg -1 ), extract high dose group (900mg.kg -1 ). Animals in each group were administered intragastrically once a day for 3 consecutive days. One hour after the last administration, the mice were placed in a 5L beaker bell jar one by one, and concentrated ammonia water was sprayed at constant pressure to observe the incubation period of mice coughing ( The time from the start of spraying to the first cough of mice), and record the number of times the mice coughed within 2 minutes (typical coughing action: contraction of abdominal muscles or chest shrinkage, while opening the mouth wide, with a coughing so...
