文摘

Two steviol glycosides were isolated from Stevia rebaudiana commercial crude extract. Four compounds were prepared from natural steviol glycosides. Chemical structures were elucidated by 1D and 2D NMR. An arabinopyranosyl steviol glycoside subfamily was described, with rebaudioside U as head of series.
