Abstract

The extract of Elsholtzia ciliata aerial parts was subjected to bio-guided isolation using the intercellular ROS reduction in J774A.1 macrophages to monitor the anti-oxidative activity. Fifteen compounds were isolated from the active fractions including eleven flavonoids (vitexin, pedalin, luteolin-7-O-β-d-glucopyranoside, apigenin-5-O-β-d-glucopyranoside, apigenin-7-O-β-d-glucopyranoside, chrysoeriol-7-O-β-d-glucopyranoside, 7,3′-dimethoxyluteolin-6-O-β-d-glucopyranoside, luteolin, 5,6,4′-trihydroxy-7,3′-dimethoxyflavone, 5-hydroxy-6,7-dimethoxyflavone (compound 13), 5-hydroxy-7,8-dimethoxyflavone); three hydroxycinnamic acid derivatives (caffeic acid, 4-(E)-caffeoyl-l-threonic acid, 4-O-(E)-p-coumaroyl-l-threonic acid) and one fatty acid (α-linolenic acid). The biological evaluation of these compounds (10–2.5 μm) indicated that all of them exerted good antioxidant and anti-inflammatory activities, in particular compound 13.
