Antinociceptive effect and mechanism of supercritical carbon dioxide extract of Aloysia gratissima leaves in mice.

Background: A. gratissima is a shrub used in folk medicine as analgesic and sedative. However, studies on its antinociceptive activity are scarce.

Antidepressant-like effect of a seeds in mice: Involvement of the monoaminergic system.

Background And Aim: Berg. (Myrtaceae) present several pharmacological actions, but there are no reports on its antidepressant-like potential. This study investigated the antidepressant-like effect and mechanism of action of seeds extract obtained from supercritical CO (40 °C, 250 bar).

Investigation of the anti-inflammatory effects of stigmasterol in mice: insight into its mechanism of action.

Stigmasterol is a phytosterol that presents pharmacologic properties. However, its anti-inflammatory mechanism and antinociceptive effect are not yet elucidated. Thus, the present study aimed to investigate the anti-inflammatory and antinociceptive activities of stigmasterol and its mechanism of action in mice.

Anti-Inflammatory Effects of Seed Extract Obtained from Supercritical CO.

is a plant species traditionally used in the treatment of diabetes, fever, hypercholesterolemia, obesity, and urinary tract diseases. The anti-inflammatory effects of leaves in mice were already known. Nevertheless, studies on the anti-inflammatory activity of its seeds are still lacking.

Antinociceptive and anti-inflammatory activities of Philodendron bipinnatifidum Schott ex Endl (Araceae).

Unlabelled: ETHNOPHARMACOLOGICAL RELEVANCE: Popular medicine use stems of Philodendron bipinnatifidum (Araceae) in inflammation cases, such as in erysipelas, as well as orchitis and rheumatism treatment. The present study, conducted for the first time in literature, investigate the antinociceptive and anti-inflammatory activities of P. bipinnatifidum stems ethyl acetate extract (EPB).

Fatty acid profile of pecan nut oils obtained from pressurized -butane and cold pressing compared with commercial oils.

This short note compares the chemical profile of pecan nut oil samples obtained from pressurized -butane and cold pressing with two commercial oils. The conventional cold pressing technique yielded 58.9 wt%, while pressurized -butane yielded from 53 to 65 wt%, being the highest yield at 55 °C, and pressure of 40 bar.

Synthesis of Ag@FeO nanocomposite based on O-carboxymethylchitosan with antimicrobial activity.

In this paper, nano-hybrid particles of Ag@FeO based on O-carboxymethylchitosan were successfully synthesized using different reducing agents (NaBH, sucrose) and without reducing agent. The smallest silver nanoparticles were those prepared without reducing agent (∼5±3nm). The average size of silver particles prepared with NaBH is around 5-15nm, and for samples prepared with sucrose, the average particle size is 10-25nm.

Extraction, chemical characterization and antioxidant activity of Sonn. and L. seeds extracts obtained from pressurized -butane.

The extraction of litchi ( Sonn.) and oat ( L.) seeds were investigated using -butane as pressurized solvent by evaluating the effect of pressure in the range of 7-100 bar and temperature from 25 to 70 °C on the extract yield and chemical composition together with the antioxidant activity of the extracts obtained.

Phytochemical profile, antioxidant and antimicrobial activity of extracts obtained from erva-mate () fruit using compressed propane and supercritical CO.

Traditionally, leaves are consumed in tea form or as typical drinks like mate and terere, while the fruits are discarded processing and has no commercial value. The aim of this work to evaluate phytochemical properties, total phenolic compounds, antioxidant and antimicrobial activity of extracts of fruits obtained from supercritical CO and compressed propane extraction. The extraction with compressed propane yielded 2.
