Biological Activities
Compounds
Conditions
Montanoa grandiflora extracts have been shown to reduce anxiety-like behavior in Wistar rats. Specifically, dosages of 25 and 50 mg/kg demonstrated anxiolytic-like effects during the metestrus-diestrus phase of the ovarian cycle. These effects were comparable to the reference drug diazepam and occurred without disrupting the rats' spontaneous motor activity. However, the plant did not produce significant behavioral changes during the proestrus-estrus phase. These findings support the traditional medicinal use of the plant to help ameliorate anxiety disorders.
Preparations
Montanoa grandiflora is prepared as aqueous crude extracts to investigate its potential pharmacological properties. These specific extracts were administered to Wistar rats at dosages of 25 and 50 mg/kg. The study focused on how these plant preparations influence anxiety-like behavior during different phases of the ovarian cycle. Results showed that the 50 mg/kg dosage of the extract exerted anxiolytic-like effects during the metestrus-diestrus phase. This preparation of the plant demonstrated efficacy similar to diazepam without disrupting spontaneous motor activity.
