Embodiment 1
[0035] Example 1: Preparation of hydroxysafflower yellow A by polyamide purification method
[0036] (1) Extraction: Weigh 20 kg of Chinese herbal medicine safflower, add 600 kg of water, and slowly stir and leach for 24 hours at 100°C, then filter, and then repeat the extraction of the filter residue twice according to the above conditions, then filter, combine the filtrate, and cool to room temperature to obtain extract A.
[0037] (2), separation: take the extract A, put it on a macroporous resin column with a column bed volume of 200L, and use deionized water at a rate of 10mL / cm 2 The flow rate of .min was eluted, and the collected eluents were combined and concentrated under reduced pressure at 100°C to a specific gravity of 1.8 to obtain concentrated solution B.
[0038] (3), pure precipitation: take the concentrated solution B, add methanol under continuous stirring to make the alcohol content reach 90%, at this time, an orange-yellow precipitate is separated out, sta...
Embodiment 2
[0042] Example 2 is the preparation of hydroxy safflower yellow A by the polyamide purification method, Example 3 is the preparation of hydroxy safflower yellow A by the macroporous resin purification method, and examples 4 and 5 are the preparation of hydroxy safflower yellow A by the silica gel purification method, Examples 6, 7, 8, 9, and 10 are for the preparation of hydroxysafflower yellow A by Sephadex gel purification. Drop into safflower drug dosage and be 20kg, concrete steps are with embodiment 1. The process conditions of each step are shown in the attached table. In the table, column packing A represents macroporous resin, B represents polyamide, C represents silica gel, D represents dextran gel; A represents methanol, B represents ethanol, and C represents acetone.
Embodiment 11
[0043] Example 11: Hydroxysafflower yellow A freeze-dried powder injection.
[0044] Hydroxysafflower Yellow A 25g
[0045] Mannitol 25g
[0046] Water for injection 400g
[0047] Weigh the dry powder of hydroxysafflower yellow A and mannitol respectively, add water for injection to dissolve and add water for injection to the full amount, stir well, filter aseptically, divide the filtrate into vials, 0.4mL per bottle, vacuum freeze-dry , press the stopper, seal the aluminum cap, and make 955 bottles of hydroxysafflower yellow A freeze-dried powder injection.
