Anti-oxidative and inhibitory activities on nitric oxide (NO) and prostaglandin E2 (COX-2) production of flavonoids from seeds of Prunus tomentosa Thunberg.

Chemical investigation of the 80% Me(2)CO extract from the seeds of Prunus tomentosa led to the isolation and identification of six flavonoids: kaempferol (1), kaempferol 3-O-alpha-L-rhamnopyranoside (2; afzelin), kaempferol 3-O-beta-D-(6-acetyl)-glucopyranosyl(1-->4)-alpha-L-rhamnopyranoside (3; multiflorin A), kaempferol 3-O-beta-D-glucopyranosyl(1-->4… CONTINUE READING
