Hidden O‐Deglycosylation Activity Triggers O → C Rearrangement for Aryl Di‐C‐Glucoside Formation by the C‐Glycosyltransferase From Fortunella crassifolia

Biotechnology and Bioengineering, EarlyView.
Here, we uncovered an unexpected O‐deglycosylation activity of the C glycosyltransferase (FcCGT), forming phloretin (1) from phloretin 2'‐O‐glucoside (2). In the presence of UDP, FcCGT catalyzes the O→C rearrangement to yield nothofagin (3). Upon additional UDP‐glucose, further C‐glycosylation occurs, forming phloretin 3',5'‐di‐C‐glucoside (4 ...

New Flavonoid Glycosides and Cyanogenic Glycosides from Dracocephalum peregrinum

Chemical and Pharmaceutical Bulletin, 2009
Separation of ethyl acetate fractionation of Dracocephalum peregrinum afforded three new flavonoid glucosides (1-3), and a new cyanogenic glucoside (4). Their structures were elucidated based on HR-electron spray ionization (ESI)-MS, EI-MS, UV, IR, 1D-, and 2D-NMR data. 1-4 were tested in vitro for their antiinflammatory activity against the RAW 264.7,
