Embodiment 1
[0032] Embodiment 1: the preparation of astaxanthin ester rich in DHA / EPA
[0033] 1) Measure 1.5 mL of free DHA / EPA, weigh 500 mg of free astaxanthin, 1600 mg of catalyst EDCL and 400 mg of DMAP and place them in a brown vial. Add 5mL of dichloromethane, fill with nitrogen and mix well after sealing. Placed in a shaking incubator at 25°C for 10 h. Synthesis of astaxanthin diester was confirmed by TLC plates.
[0034] 2) Measure 0.6 mL of free DHA / EPA, weigh 500 mg of free astaxanthin, 400 mg of catalyst EDCL and 200 mg of DMAP and place them in a brown vial. Add 5mL of dichloromethane, fill with nitrogen and mix well after sealing. Place in a shaking incubator at 25°C for 1 h. Synthesis of astaxanthin monoesters was confirmed by TLC plates.
[0035] 3) After fully dissolving the prepared DHA / EPA monoester / diester with 100mL of dichloromethane, place it in a separatory funnel. First, add 100mL of 1mol / L hydrochloric acid solution, mix well and let it stand for stratifica...
Embodiment 2
[0038] Embodiment 2: animal experiments
[0039] 2.1. Materials and methods
[0040] (1) Animal feeding and behavioral analysis
[0041] As experimental animals, male KM mice weighing 20-22 g were purchased from Beijing Weitong Lihua Experimental Animal Technology Co., Ltd. The humidity in the animal room is 65±15%, the room temperature is 23±2°C, and the light and dark alternate between 12h:12h. The mice can eat and drink freely. After one week of adaptive feeding, 64 male KM mice were divided into normal group, model control group, DHA / EPA group, AST group, DHA / EPA monoester group, DHA / EPA diester group, Astaxanthin+DHA / EPA group (1:1), astaxanthin+DHA / EPA group (1:2). The feed was modified with reference to the AIN-93G rodent feed formula, and the food intake was recorded and counted. Immediately, the back hair of all the mice was removed by chemical hair removal, and 6% sodium sulfide alcohol solution was prepared, and the depilatory agent was dipped in absorbent cotto...
