The effect of different fertilization treatments on the volatile chemical constituent and content from the leaves of Moringa oleifera were studied in this paper. Compound fertilizer, urea, potassium chloride and mixed calcium-magnesium phosphate were used, the volatile chemical constituent from the leaves were extracted by an ultrasound cleaning instrument, the volatile chemical constituent and mass fraction were analyzed by gas chromatography-mass spectrometry (GC-MS). There were 69, 70, 71 and 76 volatile chemical constituents identified respectively in the urea group, mixed calcium-magnesium phosphate group, potassium chloride group and compound fertilizer group, and the mass fraction was 77.56%, 80.09%, 86.62% and 83.13% correspondingly, while there were only 62 volatile chemical constituents with a mass fraction of 75.98 % identified in the blank control group. The contents of alcohols and alkanes were increased, and the contents of carboxylic acids, aldehydes, ketones and alkenes were decreased in the urea treatment group; the contents of alcohols and alkanes were increased, and the contents of carboxylic acids, ketones and alkenes were decreased in the calcium-magnesium phosphate group; the contents of alcohols and alkanes were increased, and the contents of carboxylic acids, aldehydes and alkenes were decreased in the compound fertilizer group; the contents of carboxylic acids, aldehydes, alkenes and ketones were decreased in the potassium chloride group. The four fertilization treatment groups had no significant effect on the contents of quinones, cyclolefins, acyls and phenols. Fertilization treatment could influence the volatile chemical constituents and contents from the leaves of M. Oleifera. The effects of different fertilizer treatments were also different. The optimum fertilizer ratio for increasing the volatile chemical compositions and contents from the leaves of M. oleifera need further study.
