Sample note
The researchers (A. Clemente, F. Pina, M.J. Melo, P. Nabais) collected the fruits between July and September in 2016, 2017 and 2018. In the 2hour-extraction of fruits, care was taken to not grind the seeds that are kept inside, as mentioned in medieval treatises which present thorough instructions not to break the fruits and free the seeds

'Ben Alder'
Sample note
The black currants (cultivar Ben Alder) were obtained from Wisley Gardens, Royal Horticultural Society, England.Fresh berry samples were frozen and stored at -20 C until transferred to the Arkansas Children's Nutrition Center, at which time the frozen samples were freeze-dried and ground into powder. The powder was kept at -70 C until analysed.
