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 treatises which present thorough instructions not to break the fruits and free the seeds. After this period, the solution presented a deep blue color. period, the solution presented a deep blue color.
