| simultaneous determination of polyphenolic compounds in red and white grapes grown in sardinia by high performance liquid chromatography-electron spray ionisation-mass spectrometry. | a new method for the identification and the quantification of nonanthocyanin phenolic compounds from six vitis vinifera grape varieties native to sardinia (three native: vermentino, malvasia and cannonau and three non-native types: chardonnay, sauvignon and cabernet sauvignon; argiolas vineyard) was developed. this rapid and selective method employs lc/esi-ms in negative mode. different solvents extraction and different sorbents for purification were compared to the direct analysis of the initia ... | 2009 | 19249789 |
| wild grapevine: silvestris, hybrids or cultivars that escaped from vineyards? molecular evidence in sardinia. | vitis vinifera ssp. silvestris, the spontaneous subspecies of v. vinifera l., is believed to be the ancestor of present grapevine cultivars. in this work, polymorphism at 13 ssr loci was investigated to answer the following key question: are wild plants (i) true silvestris, (ii) hybrids between wild and cultivated plants or (iii) or 'escapes' from vineyards? in particular, the objective of the present study was to identify truly wild individuals and to search for possible hybridization events. t ... | 2010 | 20522194 |
| predictive method for correct identification of archaeological charred grape seeds: support for advances in knowledge of grape domestication process. | the identification of archaeological charred grape seeds is a difficult task due to the alteration of the morphological seeds shape. in archaeobotanical studies, for the correct discrimination between vitis vinifera subsp. sylvestris and vitis vinifera subsp. vinifera grape seeds it is very important to understand the history and origin of the domesticated grapevine. in this work, different carbonisation experiments were carried out using a hearth to reproduce the same burning conditions that oc ... | 2016 | 26901361 |
| three years monitoring survey of pesticide residues in sardinia wines following integrated pest management strategies. | this paper reports the results of a pesticide monitoring survey on wine grapes from the 2008-2010 vintage from vineyards grown according to integrated pest management strategies. a multi-residue gas chromatography-mass spectrometry method in electron ionization and chemical ionization mode has been used for the determination of 30 pesticides in wine samples. the analytical method showed good recoveries and allowed a good separation of the selected pesticides. repeatability and intermediate preci ... | 2013 | 22976121 |
