Optimizing the conditions for extraction of Daoguleebusi-7 capsule by orthogonal experiments / 国际中医中药杂志

Objective To research the optimal conditions for extraction of Daoguleebusi-7 capsule. Methods A comprehensive investigation for the process of extraction by water and ethanol was made using orthogonal experiments.Results The optimal process conditions were: gardenia and another drug were added into 12 volumes of water, extracted 2 times and two hours per time; Sophorae Flavescentis and other four dugs were added into 12 volumes of 85% ethanol,extracted 3 times and two hours per time, elecampane was crushed and screened through 100 mesh sieve to electuary.Conclusion The extraction process is simple and feasible for operation.
