Phenolic Composition in Grape (Vitis vinifera L. cv. Malbec) Ripened with Different Solar UV-B Radiation Levels by Capillary Zone Electrophoresis.
Berli F, D'Angelo J, Cavagnaro B, Bottini R, Wuilloud R, Silva MF. msilva@fca.uncu.edu.ar.

The responses of Vitis vinifera L. cv. Malbec to different solar ultraviolet-B radiation (UV-B) levels were assessed in two contrasting situations, under sunlight with full UV-B (+UV-B) and filtered UV-B (-UV-B), in three different locations at 500, 1000, and 1500 m above sea level (asl). To evaluate the effects of radiation, a simple, accurate, and rapid method for the separation and simultaneous determination of representative phenolic compounds in grape berry skins by capillary zone electrophoresis was developed. Separation was carried out in less than 20 min with 20 mM sodium tetraborate buffer containing 30% methanol, pH 9.00. The procedure is fast and reliable, and extracted grape berry skins can be directly analyzed without prior sample cleanup procedure. Berry skins from the +UV-B treatment at 1500 m asl showed the

Thanks, yes, it was me or at least my grape-self in Argentina....

To increase the resveratrol uptake follow the instructions. After you
drink your Malbec you have to lay in a tanning bed. With special lamps
for extra UV-B.
