The petroleum ether, chloroform, methanol, and water extracts of Passiflora incarnata whole plant and sorted out plant parts have been evaluated for their anxiolytic activity using the elevated plus-maze model in mice. The methanol extracts of leaves, stems, flowers, and whole plant exhibited anxiolytic effects at 100, 125, 200 and 300 mg/kg, respectively. The roots were practically devoid of anxiolytic effects. These results show that roots and flowers of P. incarnata act as natural adulterants by causing a significant increase in the anxiolytic dose. Therefore, separation of these parts is recommended prior to any pharmacological, phytochemical and standardization studies on P. incarnata.
