The invention discloses a method for detecting the nicotine release amount in electronic smoke by using a gas chromatographic method. The method is characterized by comprising the following steps: (1) preparing extraction liquid; (2) drawing a standard working curve, wherein y is equal to 6.37927985x+0.0893433, y is a peak area ratio, x is the content of nicotine, the linearly dependent coefficient R2 is greater than 0.999; (3) preparing a sample to be detected; (4) setting operation conditions of a gas chromatograph; and (5) calculating analysis result, correcting the analysis result, reading a response value of the nicotine of the sample to be tested, calculating according to the nicotine standard curve established in the step (2) to obtain the content of nicotine of the sample. The method has the beneficial effects of being low in limit of detection, good in repeatability and applicable to detection on nicotine release amount of a cigarette product.
