Recent studies about hot-water extracts from sugar maple (Acer saccharum Marsh.) bark and buds demonstrated their potentials as antioxidant food additives. However, the phenolic structures responsible for the properties of these maple-derived extracts have yet to be determined. By performing HPLC-DAD-HRMS(/MS)-based dereplication, we were able to spike and classify almost 100 metabolites in each hot-water extract. Sugar maple bark hot-water extract is rich in simple phenolic compounds and phenylpropanoid derivatives while bud extract contains predominantly flavonoids, benzoic acids and their complex derivatives (condensed and hydrolysable tannins). Among those chemical structures, we tentatively identified 69 phenolic compounds that are potentially new to the genus Acer. Considering the growing commercial demand in natural products, the phenolic fingerprints of sugar maple bark and bud hot-water extracts will help promoting these two maple-derived products as new sources of bioactive compounds for food, nutraceutical and cosmetic industries.
