Abstract

Abstract:

Two compounds were isolated from ethyl acetate extracted fraction of Drynaria fortunei. The compounds were characterized by ESI-MS, IR, ¹H NMR, ¹³C NMR and 2D NMR (¹H-¹H COSY, HSQC and HMBC) techniques. The ¹H NMR chemical shift of the compounds were assigned. Their structures were elucidated as kaempferol-3-O-β-D-6"'-acetyl-glucopyranosyl(1→4)-α-L-rhamnoside and kaempferol-3-O-β-D-glucopyranosyl(1→4)-α-L-rhamnoside.

Key words: NMR, 2D NMR, kaempferol-3-O-β-D-6"'-acetyl-glucopyranosyl-(1→4)-α-L-rhamnoside, kaempferol-3-O-β-D-glucopyranosyl-(1→4)-α-L-rhamnoside, Drynaria fortunei, assignment
