چکیده
This article reports the ginger protease extraction and purification methods from fresh ginger rhizome. As to ginger protease extraction, we adapt the steps of organic solvent dissolving, ammonium sulfate depositing and freeze-drying, and this method can attain crude enzyme powder 0.6% weight of fresh ginger rhizome. The purification part in this study includes two steps: cellulose ion exchange (DEAE-52) and SP-Sephadex 50 chromatography, which can purify crude ginger protease through ion and molecular weight differences respectively.

Introduction: Ginger has shown anti-nociceptive effects. Here we investigated the possible involvement of GABAA receptors in anti-nociceptive effect of ginger using muscimol (GABAA agonist) and picrotoxin (GABAA antagonist) in rats that received ginger. The pain sensitivity was evaluated by formalin test. Methods: Thirty-five male Sprague-Dawley rats were randomly divided into 7 groups (n=5): s...
