Embodiment 1
[0018] Example 1 Extraction and purification of total glucosides of paeony
[0019] Take clean and dried Radix Paeoniae Alba, crush it, add 10 times the weight of 70% (v / v) ethanol, heat and extract at 65-75°C for 3 times, each time for 3 hours, combine the extracts, filter, and recover the solvent from the filtrate under reduced pressure , concentrated in vacuum into crude extract of Radix Paeoniae Alba; the crude extract of Radix Paeoniae Alba was dissolved in 20 times the weight of 70% (v / v) ethanol, adjusted to pH = 6 with sodium hydroxide solution, and HPD with polystyrene skeleton -300 macroporous adsorption resin to adsorb the solution. After the adsorption is saturated, first absorb the impurities with water until the Molish reaction is negative, and then use 70% (v / v) ethanol with 10 times the amount of resin, at a flow rate of 3 times the amount of resin / hour Elution, recovery of the eluate, concentration, drying, to obtain total glucosides of paeony as light yellow-...
Embodiment 2
[0021] Example 2 Study on anti-inflammatory immune effect of total glucosides of paeony combined with pentoxifylline on rheumatoid arthritis rats
[0022] Healthy male SD rats, clean grade, body weight (170±10) g. The rats were randomly divided into five groups, model control group, normal control group, total glucosides of paeony group, pentoxifylline group, and combined medication group, with 12 rats in each group. Except for the normal control group, the other 3 groups were treated according to the literature (Xiong Cai, Hua Zhou, Yuen Fan Wong, et al. Suppression of the onset and progression of collagen-induced arthritis in rats by QzFGJS, a preparation from an anti-arthritic Chinese herbal formula [J].Journal of Ethno—pharmacology 2007(110):39-48.) method to prepare the collagen-induced arthritis model, the rats in the experimental group were given intragastric administration on the 7th day after the model was established, once a day, continuously For 6 weeks, the normal...
