preparation example 1

[0010] Preparation Example 1: Preparation of Forsythiaside B

[0011] Take 20kg of unique medicinal material, crush it, pass through a 10-mesh sieve, add 8 times the amount (V / W) of 80% ethanol to soak overnight, reflux extraction twice, each time for 2 hours, recover the ethanol from the extract until it has no alcohol smell, filter , the filtrate was treated on the polyamide column, washed with water for 6 times the column volume and discarded, continued to elute with 10% ethanol for 4 column volumes, collected the eluate, put it on the treated polyamide column, washed with water until the effluent was colorless, and then 4 times the column volume was eluted with 5% ethanol, and the 5% ethanol eluate was collected and evaporated to dryness to obtain forsythiaside B with a content of 95%.
