Effects of leaf extracts of selected medicinal plants on blood against hypotonic solution by measuring optical density: An in vitro study

Yadav, Meena ; Chaturvedi, Gargi ; Jha, Neha


The medicinal plant leaf extracts alter the morphology of the cellular components of blood, especially RBCs. However, information on biochemical changes occurring during these events in vitro is lacking. Here, we studied the effect of medicinal plant [Azadirachtaindica A. Juss (Neem), Emblica officinalisGaertn. (Indian Gooseberry or Amla) and Ocimumtenuiflorum L. (Holi basil or Tulsi)] leaf extracts as against the hypotonic solution by measuring the optical density of blood at various wavelengths at 0 and 30 min. the blood, exposed to hypotonic solution, showed cellular degradation and higher protein metabolism; higher glucose metabolism and oxidative cellular damage as well as higher oxygen absorption as compared to test samples. Among the three leaf extracts studied, the Amla extract treatment had comparatively more protective role for cellular components of the blood as against hypotonic solution. However, Tulsi extract significantly reduced hemolysis, heme catabolism and redox stress in RBCs. Tulsi also increased glucose metabolism indicating its antidiabetic property. To conclude, Amla leaf extract significantly reversed the effects of the hypotonic solution on the cellular components while Tulsi extract exhibited therapeutic role in maintaining homeostasis of cellular components in blood
