Anthelmintic properties of Polygonum glabrum.

A K Muddathir, G Balansard, P Timon-David

    The Journal of Pharmacy and Pharmacology
    |April 1, 1987
    PubMed
    Summary

    A pure anthelmintic substance (PGA) from Polygonum glabrum shows antiparasitic and molluscicidal activity. Structural analysis indicates PGA is a terpenoid, highlighting its potential as a natural antiparasitic agent.

    Area of Science:

    • Pharmacognosy
    • Natural Product Chemistry
    • Medicinal Botany

    Background:

    • Polygonum glabrum Willd. is a Sudanese semi-aquatic plant species.
    • Natural products are increasingly investigated for therapeutic properties.

    Purpose of the Study:

    • To isolate and characterize a pure anthelmintic substance (PGA) from Polygonum glabrum.
    • To evaluate the antiparasitic and molluscicidal activities of PGA and its fractions.

    Main Methods:

    • Methanol-aqueous extraction of Polygonum glabrum leaves.
    • Isolation and purification of pure anthelmintic substance (PGA).
    • In vitro antiparasitic activity testing of plant fractions and PGA.
    • Molluscicidal activity assay against Biomphalaria glabrata and Limnea truncatula.

  • Structural elucidation of PGA using UV, IR, 13C NMR, 1H NMR, and MS spectral data.

    • Main Results:

    • A pure anthelmintic substance (PGA) was successfully isolated.
    • PGA demonstrated significant antiparasitic activity in vitro.
    • PGA exhibited molluscicidal activity against tested snail species.
    • Spectral data analysis suggests PGA is a terpenoid.

    Conclusions:

    • Polygonum glabrum contains a potent terpenoid with anthelmintic and molluscicidal properties.
    • PGA represents a promising natural compound for antiparasitic drug development.
    • Further research is warranted to explore the full therapeutic potential of PGA.
