Abstract:

The aromatic substances in fruit, pericarp, and pulp of pomegranate were extracted with headspace solid phase micro extraction and determined by GC-MS. The main aromatic substances in the fruit were aldehydes and alcohols, and their contents were respectively 78.32% and 14.52% in the entire fruit, 89.88% and 4.70% in the pericarp, and 82.15% and 9.78% in the pulp. Seventyseven kinds of the aromatic substances were determined in pomegranate fruit, among which 42, 39, and 43 kinds of substances were respectively found in the entire fruit, pericarp and pulp. There were 18 aromatic substances shared with all the three parts of the fruit and the substances were respectively 94.62%, 95.59% and 93.76% of the total aromatic substabces in the entire fruit, the pericarp and the pulp. The main aromatic substances of pomegranate were 2Hexenal, Hexanal, 3Hexenal, and (E, E)2, 4Hexadienal and their relative contents were 78.27%, 89.78%, 81.79% in the entire fruit, pericarp and the pulp, respectively. The results indicated that the main aromatic substances in the pomegranate fruit were aldehydes and alcohols which have 6 C. The various fragrances in different parts of the fruit were determined by the composition of the 6 C aldehydes and alcohols.
