| Abstract: | Objective:To optimize extraction technology of total flavonoids in Osbeckia opipara. Method: The content of total flavonoids was determined by UV spectrophotometry,with yield of total flavonoids as index,influence of extraction time,solid-liquid ratio and ethanol concentration on extraction technology of total flavonoids was investigated by orthogonal design. Result: The best extraction technology was as following:extracted 3 times with 20 times the amount of 75% ethanol,1 h each time,yield of total flavonoids 1.83%. Conclusion: This optimized technology was simple and feasible,it provide experimental evidence for fully utilization of O. opipara resources. |
