Evaluation of ethanolic extract of Piper methysticum leaves on anxiolytic activity of mice
Abstract
The ethanol extract of Piper methysticum, commonly known as kava, has shown promising results in reducing anxiety. Studies suggest it may have anxiolytic effects, potentially offering a natural alternative to conventional anxiety treatments. The ethanolic extract of Piper methysticum can increase the duration of action. It can also increase the time spent in open arm, entry in open arm (in elevated plus model) as well as increase the time spent in light field (in Light Dark field) thus we can conclude that it can also possesses Anxiolytic action. The ethanolic extract of Piper methysticum possesses an anxiolytic like activity without sedative side effect. The corticosterone level in mice is increased when they got anxiety. So when the plasma corticosterone level of mice is checked in control group its turn out to be 10.28±0.52. It gets decreased with increase in doses. When treated with low dose of Aqueous extract is 7.28±1.44 is less effective than low dose of Ethanolic extract that is 6.22±1.28. Same as that high dose of extract shows the corticosterone level was 6.24±2.28 which was also less effective than high dose of ethanolic extract which was 5.52±0.32. Most effectively stress was decreased when treated with the Standard drug (Alprazolam) which shows plasma corticosterone level was 1.24±0.36. The mice of Piper methysticum extract (300 &600 mg/kg/ p.o.) treated group showed significantly (p<0.05) increased in body water intake as compared to the control group. Results showed that synthesized extract is very effective for the treatment of anxiety.
