Title: | The distribution of phenolic acids in pumpkin's hull-less seed, skin, oil cake meal, dehulled kernel and hull | Authors: | Peričin D. Krimer V. Trivić S. Radulović L. |
Issue Date: | 15-Mar-2009 | Journal: | Food Chemistry | Abstract: | The phenolic acids in whole hull-less seed, its skin and oil cake meal, dehulled kernel and hull of pumpkin (Cucurbita pepo) were separated into free, esterified and insoluble-bound forms, which were then identified and quantified by high-performance liquid chromatography with a photodiode array detector. In all samples, protocatechuic, p-hydroxybenzoic, vanillic, trans-p-coumaric, ferulic, trans-sinapic acids and p-hydroxybenzaldehyde were quantified. Caffeic acid was present in all samples except in hulls, while syringic acid was not detectable only in skin and oil cake meal. p-Hydroxybenzoic acid was the dominant phenolic compound in all investigated samples, with 34.7%, 52.0%, 51.4%, 67.4% and 51.8% found in hull-less seed, oil cake meal, skin, dehulled kernels and hulls, respectively, based on total phenolic acid content. Most phenolic acids were present in bound (esterified and insoluble) form, from 50.6% in skin to 84.1% in hull-less seed. © 2008 Elsevier Ltd.
