“…Phenols are abundant compounds in Convolvulaceae species and TPC recorded among them is determined by various factors; values of 5.9 to 30.35% have been found in M. borneensis (Hossain & Shah, 2015), from 0.62 to 2.81% in I. reniformis (Raghuvanshi et al, 2017), and from 2.31 to 35.99% in M. mammosa (Ratnadewi et al, 2020), depending on solvent used. Similarly, it has been shown that climatic periods can regulate phenols production in M. aegyptia, with TPC ranging from 0.32% to 6.03% (Salgado et al, 2020).…”
