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.
麦芽酚葡糖苷（3-（β-D-吡喃葡萄糖苷基）-2-甲基-4H-吡喃-4-酮）1 从新西兰茶树（Leptospermum scoparium）的花蜜制剂中分离得到。1 在未衍生的花蜜的 HPLC 中洗脱后正好在二羟丙酮之后，其 UV 吸收最大值为 258nm。通过 NMR 和高分辨率质谱法确定了 1 的结构。
