ABSTRACT

Acanthopanax trifoliatus is a ginseng-like plant, which has been widely used to treat various diseases including inflammatory-related diseases. The present study has been designed to investigate the anti-inflammatory and anti-hyperalgesic effects of various fractions of Acanthopanax trifoliatus leaves ethanolic extract in rats. Anti-inflammatory activity was studied by using carrageenan-induced edema on rat paw whilst anti-hyperalgesic was assessed by using carrageenan-evoked thermal hyperalgesia on plantar test. Data were analyzed using Student t-test to compare with control.Multiple comparisons for difference between control and extract-treated groups were evaluated by Tukey HSD (Honestly Significant Difference) test. P values less than 0.05 (P < 0.05) is considered significant. Among three different fractions i.e., hexane, dichloromethane, and methanol tested, methanolic fraction displayed the most potent fraction amongst those three. It gave significant anti-inflammatory effect at highest dose, 500 mg/kg, with 77.24% of inhibition. Whilst for anti-hyperalgesic activity, methanolic fraction showed the highest efficacy at 375 mg/kg. Administration of methanolic fraction of Acanthopanax trifoliatus inhibited paw edema in a dose- dependent manner. The inhibition for both activities might be due to possible composition of polar compounds, which are flavonoids and phenolics content. Methanol fraction of Acanthopanax trifoliatus leaves has potential effect as anti-inflammatory and anti-hyperalgesia in acute inflammation model.
