In Ayurveda, five basic extraction procedures are mentioned in order of their decreasing potency. Swaras is considered as the most potent followed by, kalka, kwatha, fanta and hima.
Objective:
Present study was carried out to investigate the antioxidant and hepatoprotective potential of swaras and hima extracts of T.cordifolia and B. diffusa.
Materials and Methods:
Swaras and hima extracts of T. cordifolia and B. diffusa were prepared. Phytochemical screening and in vitro antioxidant activities was carried out using standard methods. Hepatoprotective efficacy of extracts were carried out in Swiss albino mice using paracetamol induced hepatotoxicity. Animals were administered with swaras and hima extracts of both plants at 200 mg/kg BW dose for 7 days and on 8th day hepatotoxicity was induced by intraperitoneal injection of paracetamol at 500 mg/kg BW. The degree of liver protection was determined by measuring the levels of liver enzymes followed by histopathology.
Results and Discussion:
The results of phytochemical, antioxidant and hepatoprotective activities showed that there were no significant difference between swaras and hima extracts. Both the extract of T. cordifolia were equally potent in reducing SGOT (P < 0.01) and ALP level (P < 0.001). Similar effects were observed with the Swaras and hima extracts of B. diffusa. Both the extracts reduced SGOT and ALP (P < 0.01). Histopathological findings among all the extracts were also more or less similar in lowering the paracetamol mitigated necrosis.
Conclusion:
The present study suggested that T. cordifolia and B. diffusa possess potential hepatoprotective activity irrespective of the extraction procedure.
SUMMARY
Aqueous extracts of Tinospora cordifolia and Boerhavia diffusa exhibited significant antioxidant and hepatoprotective activities
Aqueous extracts of both the plants were extracted using different extraction procedures mentioned in Ayurveda
Swaras and hima extracts of both the plants significantly reduced the deleterious effects of paracetamol, suggesting that both the plant extracts are equipotent
Acute toxicity of both the plant extracts did not produce any toxic effects.
