Chemical constituents from stem bark of Flacourtia rukam zoll. & mor. and their antioxidant activities

Exploration of chemical compounds and biological activities of extract stem bark of Flacourtia rukam have been succesfully. We have isolated and characterized three compounds friedelin (1), poliothrysoside (2), and β-sitosteryl-3β-glucopyranoside (3). The structures were identified used UV, IR and N...
