To obtain the relevant amount of those stilbenes it is essential to use effective extraction method. Considering that, comparison of several different extraction methods (maceration, ultrasonic extraction, Soxhlet and pressured liquid extraction) under various conditions such as different solvents, extraction time, temperature and exposition to the light has been performed. Results were obtained by newly modified HPLC-MS method which is proved to be accurate, reproducible and efficient for determination resveratrol and viniferin.
