ABSTRACT

Objective To discuss the best extracting technology of Evodia rutaecarpa juice——crude drug processing adjuvant of Yuhuanglian with water.Methods The content of 9 samples extracted according to orthogonal tests were mensurated by UV-spectrophotometry,and the extract methods were estimated with the content of total alkaloid in Evodia rutaecarpa as index.Results The technology of A3B2C1 that was marinated 60 minutes,added the water with 12,9.6 folds,extracted for 40 minutes,and extracted 2 times,which obtained the highest content of total alkaloid.Conclusion This test offered a pressing,feasible and best extracting technology of preparation of crude drug processing adjuvant of Yuhuanglian——Evodia rutaecarpa juice.
