“…14 This should explain the strong interaction between PVPP and tannic acid, which contains many hydroxyl groups in its numerous galloyl groups. 11,23 Similar results were related earlier for tannic acid and catechin studies using gelatin and trypsin as protein substrates. 24,25 These authors ascribed the better complexation of tannic acid to its higher molecular weight and hydroxyl density.…”

“…Both substances have the same number of non-substituted hydroxyl, so the absorption difference is probably due to the steric hindrance caused by the rutoside attached at the rutin C-3 position. 23 Following a similar train of logic, one can state that PVPP bound to pyrogallol and to rutin in a similar extent.…”

“…[52][53][54][55][56][57][58] Others proposed good swelling efficiency or high swelling pressure as the disintegration mechanism. 36,59,60 Later, strain recovery was also proposed and validated as the disintegration mechanism of crospovidone. 6,13,31…”

“…Sugerimos, então, a presença de compostos com potencial ação biológica já descrita para essa espécie, como, por exemplos, os taninos e flavonoides 3,15,16 , que apresentam atividade inibitória contra micro-organismos, além de efeito antioxidante, dentre outras atividades 9,17,18 . Dessa forma, os resultados deste trabalho corroboram para a utilização do extrato bruto de folhas de P. cattleianum sobre os micro-organismos do biofilme dental.…”
