“…Most of these studies quantified the phenolic compounds of the hemp extracts by the overall determination of the total phenolic content and total flavonoid content. In addition, several studies have quantified individual phenolic compounds, such as caffeic acid, gallic acid, rosmarinic acid, p -OH-benzoic acid, ferulic acid, 3,4-dihydroxybenzoic acid, p -coumaric acid, syringic acid, quercetin, luteolin, canniprene, cannflavin A, cannflavin B, catechin, naringenin, isorhamnetin, resveratrol, rutin trihydrate, apigenin, and apigenin 7-glucoside in the extracts [ 95 , 96 , 97 , 98 ]. Of note, most conventional extraction was conducted at room temperature and not under optimal conditions [ 99 , 100 , 101 , 102 , 103 ].…”
