Abstract: In this study,the composition of stevia and crystallization of stevia has been studie dy ultra high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS).The results showed that 45 kinds of substances were identified in stevia,among which,there were 17 species of stevia glycoside,21 amino acids,6 kinds of flavonoids,and 1 kind of saponin.9 kinds of substances were identified in the crystallization sugar,8 species of stevia glycoside and 1 kinds of amino acids.The whereabouts and distribution of various substances in the process of crystallization of stevia were clarified.A theoretical basis for improving the content of RA products was provided.

Key words: stevioside, ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS), crystallization, chemical compositio
