Objective: To investigate alcohol extraction technology of Drynaria fortunei
Radix dipsaci
Flos carthami
Eupolyphaga seu steleophaga from Jiegu Zhitong tablet. Method: Orthogonal method was used to optimize alcohol extraction conditions of main ingredients from Jieguzhitong tablet.Took yield of alcohol extracts
extraction of naringin as indexes to optimize ethanol concentration
alcohol volume
extraction time. Result: Optimum extraction technology was as follows:reflux extracted 2 times with 80% ethanol
the first time extracted 2 h with 6 times the amount of 80% ethanol
then extracted 1.5 h with 5 times in second time. Conclusion: The extraction technology of Jiegu Zhitong tablet was stable and feasible.
