Title: Optimum Extracting Technology for Total Flavonoids from Cudrania Tricuspidata by Orthogonal Test
Abstract: Objective: To optimize the extraction technology for total flavonoids from Cudrania tricuspidata,and give reference for development and utilization of total flavonoids.Methods: The process was studied by orthogonal design L9(34) with the extraction rate of total flavonoids and paste-forming rate as comprehensive index,and research the effect of alcohol amount,alcohol density,extraction duration and the extraction times on extraction rate.Results: The optimum process was as follows: the crude drug was extracted three times,the 60% alcohol density,12 times alcohol was added and 1.5 hours every time.Conclusion: This technology is reasonable and feasible,which can be used as experimental basis for extraction technology for total flavonoids.
