| Abstract | A headspace solid-phase microextraction coupled to gas chromatography with mass spectrometry and flame ionization detection (HS-SPME-GC-MS/FID) method has been developed for quantifying the main volatiles of the Italian sparkling red wine Vernaccia di Serrapetrona, leading to establish that the divinylbenzene/carboxen/polydimethylsiloxane-coated (gray) fiber, an equilibration time of 15 min, and an extraction time of 15 min at a temperature of 35 °C are the conditions representing the best compromise in terms of sensitivity and time expense, to carry out the analyses. Among the volatiles quantified, 2-phenylethanol, 3-methylbutyl acetate, and ethyl esters levels resulted to be above their odor thresholds, thus being probably responsible for the aroma of this wine with their positive attributes. Phenolic compounds, namely gallic acid, p-coumaric acid, caffeic acid, (+)-catechin, and (+)-epicatechin, were also quantified using high-performance liquid chromatography-MS, thus obtaining an overall characterization of molecules fundamental for both the sensory and the healthy characteristics of the wine. The total phenolic content was found to be in the range of 19.25–61.67 mg l$^{−1}$ with the most abundant compound being gallic acid (7.44–25.78 mg l$^{−1}$). Main differences in volatile and phenolic compounds between samples were discussed and analyzed by chemometric techniques as principal component analysis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
