Abstract:
Analysis has been carried out by GC-MS on the essential oil from the crude drug Evodia rutaecarpa and its Glycyrrihiza uralensis processed product, vinegar processed product and salt processed product. The total amount of essential oil decreases in the order of crude drug, vinegar processed, G. uralensis processed and salt processed products. The results of GC-MS analysis show that the constituents of the essential oil from the crude drug and its G. uralensis processed product are markedly different, and the contents of these constituents vary significantly.
