The aerial parts of Hypericum polyanthemum Klotzsch ex Reichardt (Guttiferae) were successively extracted with supercritical carbon dioxide (SC CO(2)) under pressures of 90, 120, 150 and 200 bar at different temperatures (40, 50 and 60 degrees C), and compared with the n-hexane extract obtained by ultrasound-assisted extraction. The samples obtained were(More)
The crude extracts of HYPERICUM species native to South Brazil showed analgesic and antidepressant-like effects in rodents. The chemical characterization of these species revealed that they are rich in flavonoids and phloroglucinol derivatives. In the present study a detailed investigation was performed on the activities of hyperoside (HYP), a common(More)
Several species of the genus Hypericum (Guttiferae) have been used for analgesic purposes all over the world and some of them have demonstrated to possess this effect in rodents. This study describes the antinociceptive effect of the cyclohexane extract from aerial parts of H. polyanthemum (POL) as well as of benzopyrans,(More)
