ABSTRACT
The study aims of this study is to analyze and evaluate the resourceful chemical compositions in different parts of mature fruit of Zanthoxylum bungeanum, and provide a scientific basis for the comprehensive utilization of this medicinal plant resources. GC-MS method was used to analyze the volatile oils and the fatty acids, and HPLC method was used to determine the flavonoids and phenolic acids in the pericarp, seed and seed oil of Z.bungeanum. There were 26, 19 and 11 kinds of volatile components detected in the pericarp, seed and seed oil, respectively, in which terpenoids and their oxy-derivatives were the main components, and the contents of linalool and its esters in pericarp were relatively high. The contents of total fatty acids in the pericarp, seed and seed oil were 108.42, 331.63, 966.04 mg•g⁻¹, respectively.Oleic acid, linoleic acid andα-linolenic acid were abundantin all samples. The pericarp contains relatively high content of flavonoids, such as hyperoside, quercitrin, rutin, isoquercitrin, while the above components were not detected in the seed and seed oil. These results confirmed that the fruit of Z.bungeanum contains high contents of the resourceful chemical compositions, and their composition and contents were differed among organs, which provide a scientific basis for the utilization of Z.bungeanumfruit.
