Flavan-3-ols are widely distributed in higher plants, such as grapes, located in the skins and seeds, being transferred to the wine during winemaking. They are responsible for specific sensory properties such as astringency, and bitterness, acting on the stability of the wine color, and taking part in the antioxidant compounds. The interest in identifying flavan-3-ols has grown in the last decades since the development of new instruments allowing a better separation and characterization, both qualitative and quantitative. New isolation, separation, and identification techniques allowed an increase in the phenolic compounds database with new structures, providing a better understanding of the mechanisms involving phenolic metabolism in grapes, wines, and other fruits and vegetables. High-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS) is one of the most relevant and used analytical techniques for the non-volatile and/or thermally unstable compounds determination. This method has shown to be valuable and robust for investigating the polyphenols (flavan-3-ols or proanthocyanidins) in grapes, wines, and derivates, in several domains, such as evaluating the effect of climate, soil, vine management, cultivars, rootstocks, protocols of elaboration, and the quality control. This chapter aims to present variations of LC-MS techniques used to identify these compounds in recent years. |

The aim of this study was to determine the favorable constant temperature range for Mahanarva spectabilis (Distant) (Hemiptera: Cercopidae) development as well as to generate geographic distribution maps of this insect pest for future climate scenarios. M. spectabilis eggs were reared on two host plants (Brachiaria ruziziensis (Germain and Edvard) and Pennisetum purpureum (Schumach)), with individual plants kept at temperatures of 16, 20, 24, 28, and 32C. Nymphal stage duration, nymphal survival, adult longevity, and egg production were recorded for each temperature*host plant combination. Using the favorable temperature ranges for M. spectabilis development, it was possible to generate geographic distribution. Nymphal survival was highest at 24.4C, with estimates of 44 and 8% on Pennisetum and Brachiaria, respectively. Nymphal stage duration was greater on Brachiaria than on Pennisetum at 20 and 24C but equal at 28C. Egg production was higher on Pennisetum at 24 and 28C than at 20C, and adult longevity on Pennisetum was higher at 28C than at 20C, whereas adult longevity at 24C did not differ from that at 20 and 28C. With these results, it was possible to predict a reduction in M. spectabilis densities in most regions of Brazil in future climate scenarios. |
