| Abstract: | Objective To research and choose the best technology conditions for estracting emodin from nepalensis spreng. Methods According to physicochemical character of emodin, orthogonal design and tests of extract technology for emodin were carried on, and three factors were chosen such as quantity of ethyl alcohol, extracting time and times, and three levels of each factor were used for orthogonal design and test. Results That was the best technology condition that emodin were extracted by means of ethyl alchhol (50%), and it is heated 3 times (each 2 h). Conclusion The technology is advanced and rational, practical and feasible. |
