Abstract

BACKGROUND:

Piper Betle, Pterospermum acerifolium, Saraca indica, Argyreia speciosa, and Rhaphidophora glauca are medicinal plants commonly used as traditional medicine for the treatment of various diseases. To examine, whether organic extracts of these plants possess thrombolytic properties with minimal or no toxicity is our main aim of the study.

MATERIALS AND METHODS:

In vitro thrombolytic model was used to check the clot lysis effects using streptokinase (SK) as a positive control and water as a negative control. Cytotoxicity was screened by brine shrimp lethality bioassay using vincristine sulfate (VS) as positive control.

RESULTS:

Among herbal drugs, different organic extracts of P. betle, P. acerifolium, S. indica, A. speciosa, and R. glauca showed significant (P < 0.05 and P < 0.0001) clot lysis activity viz., 31.58% ±0.76%, 40.50% ±0.94%, 49.70% ±1.69%, 35.81% ±0.86%, and 43.80% ±0.91%, respectively, compared to reference drug SK (79.32% ±1.629%). In brine shrimp cytotoxic assay, mortality achieved by the extracts showed lethal concentration 50 (LC50) values 274.64 ± 3.46, 215.60 ± 4.59, 478.40 ± 6.98, 233.37 ± 2.56, and 209.32 ± 1.98 μg/ml, respectively, with reference to VS (LC50, 0.05 ± 0.34).

CONCLUSION:

In this study, S. indica, R. glauca, and P. acerifolium possessed effective thrombolytic activity. Further studies can be undertaken to identify certain structure of the ingredients in the extracts and to elucidate the precise mechanism of action.

SUMMARY:

Five Bangladesh medicinal plants, named Piper betle, Pterospermum acerifolium, Saraca indica, Argyreia speciosa, and Rhaphidophora glauca were subjected to comparative antithrombotic and toxicity based analysis. In comparative study, Saraca indica showed highest clot lysis (49.70 ± 1.69%) activity among the other plant with lowest toxicity (LC50: 478.40 ± 6.98) Abbreviations Used: h: Hour; min: Minutes; sec: Second; kg: Kilogram; g: Gram; μg: Microgram; L: Liter; mL: Millilitre; μL: Micro liter; μg/mL: Microgram per Milliliter; mg/kg: Milligram per kilogram; %: Percent; °C: Degree Celsius; et al.: et alliori (and others); w/w: Weight by Weight; v/v: Volume by Volume; SEM: Standard Error Mean; LC50: lethal concentration at 50.
