Abstract/OtherAbstract:
Apple peel contains numerous phytochemicals, many of which show bioactivity. We have investigated the identity of triterpenoid compounds contained in ethanolic extracts of peel from seven apple cultivars. Using HPLC-ESI-QTOF-HRMS, accurate mass information was obtained for 43 compounds, and chemical identity was inferred from the calculated elemental composition, fragment masses, ms/ms and a limited set of authentic standards. Compounds were identified as triterpene acids and tentatively identified as ursenoic (or oleanoic) acid derivatives containing hydroxyl, oxo, and coumaryloxy groups. These apple skin extracts contained lipase-inhibitory activity, which may be linked to the ursenoic acid content. Furthermore, both triterpene content and lipase inhibitory activity varied by cultivar.
