Fecha de publicación: | 2013 | Editor: | Elsevier | Citación: | Food Chemistry 141: 2982- 2987 (2013) | Resumen: | The four stereoisomers present in a commercial sample of methyl jasmonate (MJ) were isolated at semipreparative scale by HPLC, using a permethylated b-cyclodextrin column. This allowed the baseline resolution and collection of both major (methyl jasmonates) and minor (epi-methyl jasmonates) stereoisomers. When 1.5 mL of a 5 mg per mL MJ solution were injected, isolated amounts were 3.56 mg for (#2;) and (+)-methyl jasmonates, with respective purities of 96.1% and 99.9%, and 0.18 mg for (#2;)- and (+)-epimethyl jasmonates, with 98.6% and 91.6% respective purities. The post-harvest treatment of red raspberry fruits with the pure methyl jasmonate stereoisomers isolated proved that (#2;)-epi-MJ either promotes the bioformation of (+)-limonene or inhibits that of (#2;)-limonene to a greater extent than the other three MJ stereoisomers, while the biosynthesis of the (+)-enantiomer of a-ionone is favoured equally, whichever MJ stereoisomer used. The results obtained in the present study might be used to obtain food products with improved sensory characteristics. | URI: | http://hdl.handle.net/10261/88211 | DOI: | 10.1016/j.foodchem.2013.05.117 | Identificadores: | doi: 10.1016/j.foodchem.2013.05.117 issn: 0308-8146 |
