A Villar, M C Terencio, M Paya

    Journal of Ethnopharmacology
    |June 1, 1986
    PubMed
    Summary

    Rhamnus lycioides extracts significantly lowered blood pressure in rats. Further research is needed to understand the acute toxicity and phytochemical composition of these plant extracts.

    Area of Science:

    • Pharmacology
    • Phytochemistry
    • Toxicology

    Background:

    • Rhamnus lycioides is a plant with potential medicinal properties.
    • Understanding its pharmacological effects and safety profile is crucial.

    Purpose of the Study:

    • To investigate the hypotensive effects of Rhamnus lycioides extracts.
    • To assess the acute toxicity of the lyophilized extract.
    • To identify key phytochemical constituents.

    Main Methods:

    • Intravenous administration of Rhamnus lycioides extracts to Wistar rats.
    • Acute toxicity testing in mice via intraperitoneal injection.
    • Phytochemical analysis of the plant extracts.

    Main Results:

    • Both hot water and organic solvent extracts demonstrated a reduction in systemic arterial blood pressure.
    • The lyophilized extract showed no immediate adverse effects in acute toxicity studies.
    • Phytochemical screening indicated the presence of steroids-triterpenes, catechin tannins, flavonoids, sugars, and resins.

    Conclusions:

    • Rhamnus lycioides possesses significant blood pressure-lowering properties.
    • The plant extract appears to have a favorable acute toxicity profile.
    • The identified phytochemicals may contribute to the observed pharmacological activity.
