对挥发性成分提取方法进行优选，用正交设计法，确定了最佳提取工艺。选择了喷雾干燥的进风温度，并研究了辅料配比对其成品率的影响，结果表明；最佳工艺为水蒸气蒸馏法提取挥发性成分，蒸馏液量与生药比为5：1，其余药材水煎2次．每次1h，浓缩成浸膏，加蒸馏液，糊精（约干浸膏0．66倍），喷雾干燥进风温度为145～155℃。 The method of extracting the volatile components was optimized, and the optimum extraction process was determined by the orthogonal design method. The spray drying air inlet temperature was selected, and the effect of excipient ratio on the finished product rate was studied. The results showed that the optimal process was steam distillation for the extraction of volatile components. The ratio of distilled liquid to crude drug was 5:1. Herbal decoction 2 times. Each time 1h, it was concentrated into extract, plus distillate, dextrin (about 0.66 times dry extract), and the spray drying air temperature was 145-155°C.
