Comparative biological activity study on Passiflora incarnata and P. edulis

Area of Science:

• Pharmacology
• Ethnobotany
• Plant Science

Background:

• Passiflora incarnata and Passiflora edulis are plant species with debated identities and potential medicinal uses.
• Previous research has clarified the botanical classification of these two Passiflora species.
• Anxiety disorders are prevalent, driving the search for effective therapeutic agents, including those from natural sources.

Purpose of the Study:

• To comparatively investigate the anxiolytic (anxiety-reducing) activity of Passiflora incarnata and Passiflora edulis.
• To validate and build upon the recently established correct identities of these two plant species.
• To determine if the distinct identities correlate with differing pharmacological effects.

Main Methods:

• Preparation of methanol extracts from both Passiflora incarnata and Passiflora edulis.
• Administration of oral doses of the extracts to test subjects.
• Evaluation of anxiolytic activity using established pharmacological models.

Main Results:

• The methanol extract of Passiflora incarnata demonstrated significant anxiolytic activity at an oral dose of 125 mg/kg.
• Passiflora edulis extract did not exhibit any significant anxiolytic activity in the tested models.
• The findings support the differentiation of the two species based on their pharmacological properties.

Conclusions:

• Passiflora incarnata possesses notable anxiolytic properties, supporting its traditional use for anxiety.
• Passiflora edulis lacks significant anxiolytic activity, indicating a distinct pharmacological profile.
• This study reinforces the importance of correct plant identification for reliable medicinal applications.
