Objective: 10 optimize the preparation of cutting-processed Arecae Pericarpium by the orthogonal method.
Methods: With four alkaloids such as arecoline, arecaidine, guvacoline, guvacine and yield of water-soluble decoction as indexes, a L9 (3(4)) orthogonal test was adopted to compare the effect of different factors on cutting-processed Arecae Pericarpium.
Results: According to the finalized optimal process, Arecae Pericarpium was washed quickly, moisturized, chopped lengthwise in 1 cm segment and then dried for 2.5 h at 50 °C.
Conclusion: The optimal process method is reasonable and reliable, it can provide basis for the preparation of cutting-processed Arecae Pericarnium.
