- Abstract
Grevillosides R-S (1–2), two new glucosides of 5-alkylresorcinol derivatives, were isolated from the roots of Ardisia crispa (Thunb.) A. DC. The structures of grevillosides R-S (1–2) were determined by 1D and 2D NMR, HR-MS, UV, IR experiments and by comparison of their spectroscopic and physical data with literature values. In this paper, grevillosides R-S (1–2) were tested for their radical-scavenging activity (DPPH and ABTS) and α-glucosidase inhibitory activity in vitro. Grevillosides R-S (1–2) exhibited weak DPPH radical-scavenging activity with IC50 values of 72.3 and 485.2 μM, respectively. Grevillosides R-S (1–2) exhibited no inhibitory activity against α-glucosidase.
