Abstract:
OBJECTIVE:To optimize the extraction technology of total flavonoids for Bone healing formulation in order to use it for preparation research. METHODS:With the content of total flavonoids as the index,L9(34)orthogonal test was employed to investigate the effects of volume fraction of the solvent ethanol,the amount of solvent,extraction times and extraction time on the extraction of total flavonoids for Bone healing formulation to determine the optimal levels of the factors,and verification tests were conducted. RESULTS:The optimal extraction technology of total flavonoids was 1 h reflux extraction for 3 times,with 70% etha-nol 10 times as much as the amount of medicinal materials. Verification tests showed the average content of total flavonoids was 62.03 mg/ml(RSD=0.84%,n=3),that is to say,6.20 g total flavonoids might be extracted from 100 g medicinal materials for the formulation. CONCLUSIONS:The optimal technology is stable and feasible and can be used for the extraction of total flavo-noids for Bone healing formulation and provide a experimental basis for the preparation of Bone healing liniment.
