preparation example 1
[0040] Preparation Example 1: Inula Inula Extract
[0041] (1) Inula inula is crushed through an 80-mesh sieve to obtain inula inula powder;
[0042] (2) Mix Inula inula powder and 80% ethanol by mass fraction according to the weight ratio of material to liquid: 1:10, use ultrasonic extraction, the extraction temperature is 60°C, the extraction time is 2h, and the extraction power is 500W to obtain the extract;
[0043] (3) The extract is filtered, and the filtrate is vacuum concentrated to a relative density of 1.23 to obtain Inula inula extract

[0044] Preparation Example 2: Aloe Vera Extract
[0045] (1) crush the aloe vera;
[0046] (2) Mix the aloe vera powder and 75% ethanol according to the weight ratio of material to liquid: 1:10, soak for 3 hours, reflux extraction for 2 hours, reflux extraction twice, filter, collect, and combine the filtrates into a crude extract;
[0047] (3) Filtrating the crude extract and concentrating under reduced pressure to obtain the crude extract of aloe;
[0048] (4) Dissolve the crude extract of aloe vera with 7 times of water, put it on a macroporous adsorption resin column, wash with water, elute with 75% ethanol aqueous solution, and collect the ethanol eluate;
[0049] (5) Filter the ethanol eluent, concentrate under reduced pressure to a relative density of 1.25, and obtain an aloe extract.
