Volatile composition of Mencia wines
Monovarietal Mencia wines from two different Appellation of Origin Controlled (AOC) of Galicia (NW Spain) were analyzed. The content of some varietal and fermentative volatile compounds was determined by gas-chromatography and GC-mass spectrometry. These red wines, independently of their origin, showed terpene profiles, that were typical of their varietal characteristics with an important contribution of linalool, citronellol, alpha-pinene and beta-pinene. Other important varietal compounds were: norisoprenoids (alpha- and beta-ionone, and theaspirane), phenyl-ethanol and benzyl alcohol. The 67 analytical variables were submitted to analysis of variance, and the results showed that only nine volatile compounds were significantly different (p<0.05) among the two AOC (trans-3-hexenol, 1-butanol, isobutanol, ethyl acetate, hexyl acetate, butyric acid, gamma-butyrolactone, methionol, and N-(2-hydroxy-ethyl)-acetamide). Principal component analysis showed the differentiation of wines according to geographical areas. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 105-21-5, and how the biochemistry of the body works.Synthetic Route of 105-21-5
