Abstract:
Objective: To investigate the influence of different drying methods on physical fingerprint and total flavonoids content of Mori Ramulus extract.Method: The Mori Ramulus extract was dried by freeze drying,vacuum drying,ambient pressure drying,respectively.The content of total flavonoids in samples with different drying methods were determined and compared with each other.Physical fingerprint of Mori Ramulus extract was established by radar map and the physical fingerprint of samples with different drying methods were compared with each other.In the meantime,compressible parameters were employed to analyze the compressibility characteristics of Mori Ramulus extract treated by different drying methods.Result: Similarity of control physical fingerprint of Mori Ramulus extract treated by different drying methods was 77.8%-87.3%,relative standard deviation(RSD) of average value of the first level indexes and the compressible parameters was 0-16.6%.Except for homogeneity and stability,the remaining RSDs were less than 10%.Effects of different drying methods on homogeneity and stability of Mori Ramulus extract were greater than that of other factors.Conclusion: Different drying methods have certain effects on physical fingerprint of Mori Ramulus extract,but they have little influence on total flavonoids content in Mori Ramulus extract.
