It is necessary to determine the quantity of metal elements in aloe for the development of the aloe industry. The Microwave Plasma Torch Atomic Emission Spectroscopy (MPT-AES) is applied in analysis and testing of aloe in this paper. The contents of calcium, magnesium, iron and zinc in Chinese and Yuanjiang aloes were determined, respectively, by the 510 model MPT spectrograph. Various experimental parameters (including analytical wavelength, microwave forward power, support gas flow rate, carrier gas flow rate and oxygen shield gas pressure) were obtained and optimized systematically. Under the optimal conditions, the detection limits for Ca, Mg, Fe, Zn were 5.62, 3.03, 78.36, 25.41ng/mL, respectively, with linear ranges of 0.05～100, 0.01～100, 0.2～20, 0.1～20?滋g/mL. All of the RSDs were less than 1.48%, and the recovery rates of these elements were around 96.5%～102.4%. The results show that the method is simple, rapid, accurate and of great application value. The contents of metallic elements in Chinese aloe and Yuanjiang aloe are almost the same, but Chinese aloe contains more iron than Yuanjiang aloe., authors=null, authorsList=null, authorCompany=null,
