Assessment of Thrombolytic & Cytotoxic Activity of Herbal Preparations Originated from Botanical Source of Bangladesh.

ABSTRACT

An in vitro thrombolytic model was used to check the clot lysis effect of four herbal extracts viz., Honey, Nigella sativa, Capsicum frutescens, Brassica oleracea, combination of Honey & Nigella sativa and Honey & Capsicum frutescens along with Streptokinase as a positive control and water as a negative control. And also brine shrimp lethality bio-assay was done using brine shrimp Nauplii and 5% of DMSO as a solvent for the ethanol extracts of Nigella sativa & Capsicum frutescens and Honey. Using an in vitro thrombolytic model, Honey, Nigella sativa, Capsicum frutescens, Brassica oleracea, combination of Honey & Nigella sativa and Honey & Capsicum frutescens showed 26.82%, 47.13%, 57.40%, 62.44%, 56.58% and 44.54% clot lysis effect respectively. From our study we found that Brassica oleracea, Capsicum frutescens, and combination of Honey & Nigella sativa showed significant % of clot lysis effect with reference to Streptokinase. Again from in vitro brine shrimp lethality bio-assay, we found that the LC50 of Honey, Capsicum frutescens & Nigella sativa were 129.62 μg/ml, 83.33 μg/ml & 45.45 μg/ml respectively.
