Embodiment 1
[0021] Embodiment 1, alcohol extraction method prepares chuanxiong lactone I
[0022] Chuanxiong decoction pieces 1kg, after removing impurities, crushed into powder, 70% ethanol 10L 90 ℃ reflux extraction twice, each time 2 hours, combined extracts, recovered about 8L of solvent to obtain 2L of extract A (equivalent to crude drug 0.5g·ml -1 ). Extract A solution 5000r·min -1 Centrifuge for 15 min, and take the supernatant (the floating oil in the upper layer is discarded). 240g of HPD-100 macroporous resin (equivalent to 80g of dry resin) was wet-packed, the extract A solution was loaded, and the adsorption flow rate was about 0.7L h -1 . After the sample was loaded, it was washed with 3.5 L of distilled water until it was nearly colorless, and then 1.4 L was eluted with 50% 7 alcohol, the alcohol eluate was collected, and the solvent was recovered to obtain extract B. Dissolve extract B in 500ml of distilled water to obtain an aqueous solution of extract B, extract with ...
