Embodiment 1
[0022] Embodiment 1. The preparation of the total alkaloids of Shujincao
[0023] Take 1kg of Shujincao crude drug, add 8L of 1% HCl aqueous solution (solid-to-liquid ratio 1:8) and heat at 80°C for three times. The extracts were combined, filtered, concentrated to 5 L under reduced pressure, an appropriate amount of 2% NaOH solution was added to adjust the pH to 9, and then extracted three times with 2 L of dichloromethane. The dichloromethane layers were combined, and the solvent was recovered to dryness to obtain the total alkaloids of Shujincao.
Embodiment 2
[0024] Example 2. The effect of total alkaloids of vine stone pine on arthritis rats induced by complete Freund's adjuvant
[0025] (1) Experimental method
[0026] Rats are divided into five groups, i.e. normal group, model group, positive drug group (diclofenac sodium 10mg / kg), the high-dose group (40mg / kg) of total alkaloids of Shujincao prepared in embodiment 1 and embodiment 1 The prepared Shujincao total alkaloid low dose group (20mg / kg). Inflammation was induced by intradermal injection of complete Freund's adjuvant in the right hind paw of rats (except normal group). From the second day of inflammation, the drug was given by intragastric administration once a day for 28 days. The degree of swelling and arthritis index of rats' inflamed lateral paws were evaluated on the 7th day, 14th day, 21st day and 28th day of administration, respectively. After 28 days of administration, blood was collected under anesthesia, and peripheral blood lymphocytes and neutrophils were ...
Embodiment 3
[0053] Take 1kg of Shujincao crude drug, add 5L of 2% HCl aqueous solution at 70°C and heat for extraction 4 times. The extracts were combined, filtered, concentrated under reduced pressure to 4 L, and an appropriate amount of 5% NaOH solution was added to adjust the pH value to 10, followed by extraction with 2 L of dichloromethane for 4 times. The dichloromethane layers were combined, and the solvent was recovered to dryness to obtain the total alkaloids of Shujincao.
