Abstract:
Background: Extreme generation of free radicals leads to oxidative stress which has been apprehensive in several disease processes such
as diabetic complications and vascular and neurodegenerative diseases. Objective: The present study was designed to evaluate the potential
of homoeopathic preparations of Cephalandra indica L. against oxidative stress. Materials and Methods: Potencies of Cephalandra
indica (mother tincture, 6C and 30C) were procured from Dr. Willmar Schwabe India Pvt. Ltd. The antioxidant activity of Cephalandra indica
was evaluated by employing various in vitro antioxidant methods. Results: The total phenol content was found to be 1905, 849 and 495 mg/g
gallic acid equivalents in mother tincture, 6C and 30C of Cephalandra indica and total antioxidant capacity was found to be 2710, 759 and
510 µM/g ascorbic acid equivalents, respectively. Mother tincture, 6C and 30C of Cephalandra indica was found to have strong reducing
power, 2,2‑diphenyl‑1‑picrylhydrazyl radical, hydrogen peroxide, nitric oxide and superoxide radical scavenging activity. Percentage inhibition
of AGEs formation by mother tincture, 6C and 30C of Cephalandra indica (10–50 µl) was found to be 30.34%–91.77%, 29.98%–65.71% and
33.05%–57.75%, respectively. Mother tincture, 6C and 30C of Cephalandra indica showed inhibitory effect against sorbitol accumulation
with IC50 value of 26.12 µl, 203.10 µl and 897.3 µl, respectively, whereas, in aldose reductase inhibition assay, the IC50 value was 32.54 µl,
175.02 µl and 834.34 µl, respectively. Conclusion: The results revealed that homoeopathic preparations of Cephalandra indica exhibit
protective effect against oxidative stress.
