“…Castor bean leaves have been used as a medicinal plant due to the presence of phytochemicals, mainly phenolic compounds such as flavonoids (rutin, quercetin, and (+)-catechin), hydroxycinnamic acids (caffeic, chlorogenic, p -Coumaric, and sinapic acids), and hydroxybenzoic acids (gallic and ellagic acids) [ 15 ].
