An analytical method on sensitivity of methyl farnesoate in lymph and muscle of cultured Portunus trituberculatus is introduced using capillary gas chromatography-mass spectrometry. After nonadeeanoic acid methylester is added to lymph and frozen drying muscle as inner standard, and 0.9% NaCl and acetonitrile are added to lymph, methyl farnesoate can be extracted with n-hexane effectively, and determined using EI-SIM-MS after concentration. The results indicate that methyl farnesoate and the inner standard can be separated from each other on SBP-1 column with sharp peak. The linearity is agreeable from 5.00 to 200.00ng.mL^-1 and relative coefficient is found to be 0.999 95, with low detection limit of 3.27 pg. The average recovery rate in lymph and muscle is 95.32% and 88.37%, respectively, and the standard deviation reads 5.71% and 7.94%, respectively. This method is applied to determine the methyl farnesoate at different stages of P trituberculatus, coming up with the results of 15.11-145.23 ng.mL^-1 in lymph and 3.23-10.32 ng.g^-1 in muscle.
