| 摘 要： | Two new isobutyltartrate monoesters,coelovirin A (1) and B(2),were isolated from the rhizomes of Coeloglossum viride (L.) Hartm. var. bracteatum (Willd.) Richter (Orchidaceae). Their structures were elucidated as (2R,3S)-2-isobutyltartrate-1-(4-β-D-glucopyranosyloxybenzyl) ester 1 and (2R,3S)-2-isobutyltartrate-4-(4-β-D-glucopranosyloxybenzyl) ester 2 on the basis of physical constants and spectroscopic methods including 2D NMR techniques.
