The invention discloses a marker and a method for rapidly identifying multiple stoving traditional Chinese medicinal materials. The 2-sulfotryptophan can be used as a stoving marker for identifying stoving traditional Chinese medicinal materials, and the traditional Chinese medicinal materials are radix ophiopogonis, fritillaria, houttuynia cordata, rhizoma anemarrhenae or lily. The method for identifying the stoving traditional Chinese medicinal materials comprises the following steps: S1, crushing a to-be-detected sample, dissolving the crushed to-be-detected sample in a methanol solution, uniformly mixing, performing centrifugal separation, and filtering to obtain filtrate; s2, the filtrate is subjected to UPLC-Q-TOF-MS analysis, a total ion flow chromatogram is obtained, and when the total ion flow chromatogram comprises a molecular ion peak of 2-sulfotryptophan, the to-be-detected sample is the stoving traditional Chinese medicinal material. The UPLC-Q-TOF-MS combined metabonomics statistical method is a
