Okamura N, Haraguchi H, Hashimoto K, Yagi A
Flavonoids in Rosmarinus officinalis leaves
Phytochemistry 37 (1994)
1463-1466
Three new flavonoid glucuronides, luteolin 3'-O-β-D-glucuronide, luteolin 3'-O-(4"-O-acetyl)-β-D-glucuronide, and luteolin 3'-O-(3"-O-acetyl)-β-D-glucuronide, together with hesperidin, were isolated from 50% aqueous MeOH extract of the leaves of rosemary. The structures were established by chemical and spectroscopic methods. Their antioxidant activities were evaluated by a ferric thiocyanate method with hesperidin showing the greatest activity.
