Embodiment 1
[0055] The method of mogrosin alcohol derivative shown in formula (I), it comprises:
[0056] Step a, weigh 5g of sodium periodate in an Erlenmeyer flask, dissolve it with 50ml of water (1ml of acetic acid to aid dissolution), then add 50ml of acetone (keep the solvent system as acetone:water=1:1), and set aside; Dissolve 5 g of mogrosin in a round bottom flask with 50 ml of acetone, then add 50 ml of water, stir at 60°C and slowly add the freshly prepared sodium periodate solution, complete the addition within 30 minutes, and react in the dark for 20 hours, evaporate the acetone under reduced pressure, Dilute with an appropriate amount of water, extract three times with dichloromethane, combine the organic phases, dry over anhydrous magnesium sulfate, evaporate the solvent under reduced pressure, separate and purify by silica gel column chromatography (dichloromethane / ethyl acetate=4:1), and obtain intermediate Body A;
[0057] Step b, weigh intermediate A3g in a 250ml round...

Embodiment 3
[0067] A compound for removing freckles, fine lines, dark circles and bags under the eyes, including Mogrosanol methionine ester derivatives and rose pomace alcohol extract in a weight ratio of 1:1.8. Among them, the preparation steps of the rose residue alcohol extract are: adding rose residue to 50% ethanol solution according to the ratio of material to liquid 1:25 (g / mL) and then placing it in an ultrasonic extractor, ultrasonically assisted extraction for 45 minutes, and filtering to remove the suspended extract. particles, take the filtrate and centrifuge at 13,000 rpm for 15 minutes, collect the supernatant, remove the extractant by rotary evaporation, and vacuum freeze-dry to obtain the rose pomace alcohol extract.
