Membrane stabilization activity as anti-inflammatory mechanisms of Vernonia amygdalina leaves extracts

Abstract

Inflammation is a normal process in the human body as a response to injury from healing process. Meanwhile, chronic inflammation will cause new health problems to patients. Anti-inflammatory agents generally used for those conditions, have several side effects to patients. The aim of this research was to find alternative anti-inflammatory agents, especially from natural sources. Vernonia amygdalina knew locally as “daun afrika” belong to family Apiaceae is one of those potential natural sources for alternative anti-inflammatory agents. This plant is known astraditionalmedicine from East Kalimantanfor health problems caused by the muscle stiffness and used as material in this research. The experimental method of anti-inflammatory measurement using membrane stabilization activity for V. amygdalina leaves extracts. The results showed that significant differences of EC50(p<0.05)achieved between indomethacin as the positive control (26.39 ± 2.91 µg/mL) with V. amygdalina leaves extracts for concentration 1% (131.81 ± 2.95 µg/mL) and 10% (62.54 ± 2.05 µg/mL). EC50 of V.amygdalina leaves extracts showed the potential anti-inflammatory activities. It could be concluded that V. amygdalina leaves extracts to have anti-inflammatory activities, which could be further developed as a new natural source of the anti-inflammatory agents.
