The invention discloses a method for extracting components in mint by utilizing a Soxhlet extraction device with a solid-phase extraction function. The method comprises the following steps: (1) extracting a mint sample and refluxing; (2) concentrating the mint sample; and (3) carrying out analysis on the to-be-detected sample concentrated in the step (2) by using LC-MS. According to the invention,the Soxhlet extraction device with the solid-phase extraction function is self-made, samples can be separated, purified and concentrated under the closed condition, the traditional operation steps ofseparating, purifying and concentrating for multiple times are not needed, and the extraction efficiency is greatly improved.
