ABSTRACT
2-O-ß-d-Glucopyranosyl l-ascorbic acid (AA-2ßG) is a stable, bioavailable vitamin C (AA) derivative. We report the distribution and seasonal variation of AA-2ßG in apples and its occurrence in other domesticated crops and in wild harvested MaÌ
ori foods. Liquid chromatography-mass spectrometry analyses showed high AA-2ßG concentrations in crab apples (Malus sylvestris) but low concentrations in domesticated apples. Leaves of crab and domesticated apple cultivars contained similar intermediate AA-2ßG concentrations. Fruits and leaves of other crops were analyzed mainly Rosaceae but also Actinidiaceae and Ericaceae. AA-2ßG was detected in all leaves (0.5-6.1 mg/100 g fr. wt.) but was at lower concentrations in most fruits (0.0-0.5 mg/100 g fr. wt.) except for crab apples (79.4 mg/100 g fr. wt.). MaÌ
ori foods from Solanaceae, Piperaceae, Asteraceae, and a fern of Aspleniaceae also contained AA-2ßG. This extensive occurrence suggests a general role in AA metabolism for AA-2ßG.
