Embodiment 1
[0025] Example 1: Preparation process of the effective part of Baiziren
[0026] (1) Take 1000g of Boziren medicinal material, wash, dry, crush and pass through a 60-mesh sieve to obtain a coarse powder;
[0027] (2) Extract 10 times the amount of 75% ethanol with 75% ethanol, reflux at 60°C for 4 times, 4 hours each time, filter, combine the two filtrates, and concentrate the filtrate to obtain the extract;
[0028] (3) Add 4 times the amount of water to dissolve the obtained extract, and then adsorb it on a D101 macroporous resin column, then wash it with deionized water until the effluent is colorless, and then elute it with 95% ethanol solution;
[0029] (4) Combine the eluate purified by the macroporous resin, concentrate with a rotary evaporator, and evaporate to dryness under vacuum at 60°C to obtain the effective fraction of Cypress kernel.
Embodiment 2
[0030] Example 2: In vivo study proves that the effective part of Baiziren has therapeutic effect on APP / PS1 double transgenic dementia mice
[0031] 1 material
[0032] 1.1 Experimental animals
[0033] Forty-eight 5-month-old APP / PS1 double transgenic mice, male, weighing 25±2g, SPF grade, and 8 C57BL / 6J mice with the same genetic background were normal controls.
[0034] 1.2 Experimental drugs and reagents
[0035] The positive control drug is donepezil hydrochloride (trade name: Aricept), 5 mg / tablet, the tablet is ground into powder before use, and double-distilled water is used to make a drug solution for oral administration of 0.65 mg / kg d - 1 ; Huperzine A Capsules were prepared with double distilled water to make a drug solution for gastric administration, and the prepared concentration was 0.026mg / kg·d - 1 . Acetylcholinesterase (AChE) kit, choline acetyltransferase (ChAT) kit, SOD activity kit, MDA content kit, GSH content kit. The effective part of Baiziren is...
