Objective:To optimize extraction process of total polypeptides from Moschus and provide a reference for species identification and quality evaluation of Moschus. Method: The content of total polypeptides was determined by Folin phenol method.With the content of total polypeptides as index
orthogonal test was adopted to optimize extraction process by taking extracting time
the amount and type of solvent as factors. Result: Optimum extraction process of total polypeptide was as follows:with Tris-HCl buffer(pH 8.0
0.025 mol · L-1) as extracting solution
grinding time of 3 h
solid-liquid ratio of 1: 100;the content of total polypeptides was 20.71%
after freeze-drying
yield of total polypeptides was 62.4%. Conclusion: Optimized extraction process is stable and feasible with high extracting rate
this method can provide experimental basis for quality analysis of Moschus.
