Besides the basic nutritional compounds the human diet contains a series of natural essences, that without having specific nutritional characteristics show biological activity, and can therefore be referred as phytochemical compounds. The red wine is a discrete source of phytochemical compounds positively interacting with the human organism. Among them, quercetin together with t r a n s-resveratrol are the most represented. In particular wine represents the main source of resveratrol, being fruits and vegetables the most relevant source of quercetin. The aim of the study was to determine phytoestrogens quercetin and trans-resveratrol in samples of Tuscany red wine. In order to do this, 13 wine samples from 7 producers of the area of Morellino di Scansano (Grosseto, Italy) and 13 wine samples obtained from the Chianti area (Siena, Italy) were analysed and c o m p a r e d . All the analysed samples were directly picked up from the bottle, protected from the sunlight and injected in HPLC system with diode array scan system, without any purification, extraction or filtration procedure of the wine samples. The data we obtained showed that quercetin is highly present in all the samples, with a mean value almost always above 10 mg/L and with a peak of about 20 mg/L. Similarly, the results obtained in the trans-resveratrol assays showed that the values found in samples of the Morellino and Chianti wines were, on the average, slightly higher than those reported in the international literature. In conclusion, from our analyses we observed that the phytoestrogens (quercetin and resveratrol) in the studied Tuscany red wines are well represented and correlate with grapevine variety and the soil
