Identification of the flavonoid fraction in saffron spice by LC/DAD/MS/MS: Comparative study of samples from different geographical origins
Abstract The flavonoid fraction in saffron spice has been analysed, for the first time, by LC-DAD-MS/MS ESI and five kaempferol derivatives have been found. Compounds such as… Expand

Crocetin esters, picrocrocin and its related compounds present in Crocus sativus stigmas and Gardenia jasminoides fruits. Tentative identification of seven new compounds by LC-ESI-MS.
Crocetin esters present in saffron (Crocus sativus L.) stigmas and in Gardenia jasminoides Ellis fruit are the compounds responsible for their color. Of the fifteen crocetin esters identified in this… Expand

Influence of prefermentative maceration temperature on the colour and the phenolic and volatile composition of rosé wines
Prefermentative maceration for 8 h at 5, 10 and 15 °C was used to make rose wines, and changes in their colour (colour intensity (CI), tone and CIELAB parameters), phenolic compounds (classic indices… Expand

Stir bar sorptive extraction applied to volatile constituents evolution during Vitis vinifera ripening.
The stir bar sorptive extraction (SBSE) technique is used to determine volatile constituents in Monastrell grapes. The method proposed involves a maceration step lasting 2 h and a sorption time of 6… Expand

Analysis of saffron volatile fraction by TD–GC–MS and e-nose
Saffron spice is valuable for its colour, taste and aroma. All these properties depend on the different postharvesting treatments that Crocus sativus L. stigmas received to convert it into a spice.… Expand
