Phenolic glycosides isolated from the bark of Lysidice brevicalyx Wei.
Two new compounds, lysidiside S (1) and 7-O-(+)-peltogynol-beta-d-glucopyranoside (2), together with six known phenolic glycosides (3-8) were isolated from the bark of Lysidice brevicalyx Wei. The structures of these compounds were characterized by chemical and spectroscopic methods. The antioxidant activities of compounds 1-8 were evaluated, and compound 3 exhibited remarkable antioxidant activity at concentrations of 10(-4), 10(-5), and 10(-6) mol/l.
