title: Isolation of maltol glucoside from the floral nectar of New Zealand mānuka (Leptospermum scoparium).
abstract: Maltol glucoside (3-(β-D-glucopyranosyloxy)-2-methyl-4H-pyran-4-one), 1, was isolated from a preparation of the floral nectar from the New Zealand mānuka tree (Leptospermum scoparium). 1 eluted just after dihydroxyacetone in HPLC of underivatized nectar and showed a UV absorbance maximum of 258 nm. The structure of 1 was confirmed by NMR and high resolution mass spectrometry.
