Rebaudioside A and other unreported steviol glycoside isomers found in the sweet tea (Rubus suavissimis) leaf

In this study, we conducted an analysis of sweet tea leaves by using high performance liquid chromatography coupled with a mass spectrometer (LC–MS), and reported for the first time that rebaudioside A, one of the major steviol glycosides in Stevia rebaudiana Bertoni, was detected in Rubus suavissimis, along with a few other isomers of stevioside or rebaudioside B. This finding has potential implications on selective plant breeding, an effort already in place in an attempt to increase the abundance of desirable steviol glycosides, such as rebaudioside D and M, the concentrations of which are very low in current stevia plants.Graphical abstract
