Embodiment 1
[0027] The preparation of embodiment 1 fine diosgenin, diosgenin and protodioscin
[0028] Smilax crude drug 1kg was refluxed in 75% ethanol water bath for 2h, and the ethanol extract was collected. After 3 alcohol extractions, the alcohol extracts were combined. After recovering ethanol, put it on a polyamide column (30-60 mesh) at a flow rate of about 5BV (volume of polyamide) h. The column was washed with distilled water, and the water washings were collected. Then with 95% ethanol, the flow rate is about 2.5BVh. Rinse the polyamide column and collect the eluate. Use NaHCO3 to adjust the pH value of the above-mentioned washing solution to 4-5, add sodium chloride to 1.5 mol / L, put it on a macroporous resin column (D101, resin branch of Tianjin Pesticide Co., Ltd., batch number: 20020407), and wash it with water until Eluate to neutral. With 75% ethanol, the flow rate is about 2.5BVh. Rinse, collect the eluate, and recover ethanol through a rotary evaporator to obtain ...
Embodiment 2
[0029] Example 2 Preparation of preparation containing fine diosgenin (1)
[0030] Take 80 g of fine diosgenin prepared according to the method of Example 1, add 5 g of poloxamer, 2.5 g of povidone, 2.5 g of lecithin, and 5 g of microcrystalline cellulose. The above ingredients are fully mixed, and 5 g of 10% starch slurry is added as a binder, then granulated, dried, and sized to prepare 200 tablets in total and coated.
Embodiment 3
[0031] Example 3 Preparation of slimy diosgenin preparation (2)
