Antioxidant Activity of Lawsonia alba Mediated Silver Nano-Particles


Abirami Arthanari*, Kandhal Yazhini and S Rajeshkumar

Introduction: Lawsonia Alba is commonly known as Henna and abundantly available in tropical and subtropical areas. Lawsonia Alba  is cultivated  for  the medicinal and cosmetic value of its leaves. The shrub’s stem bark, roots, flowers, and seeds have also been used in traditional medicine. Silver nanoparticles (AgNPs) have a wide range of medicinal and diagnostic uses. Silver is one of the most common metal nanoparticles, owing to its antimicrobial and pharmaceutical properties. It is in the medical industry as topical ointments to prevent infection against burn and  open wounds. Antioxidants are  compounds that may  shield the cells from free radicals, which may cause heart disease, cancer, and other illnesses.

Aim: In the present study, we aim to evaluate the antioxidants activity of Lawsonia Alba mediated silver nanoparticles.

Materials and methods: The  research involved preparing Lawsonia Alba extract and  20  milli molar silver.  Both were mixed and  stirred using a  magnetic stirrer  for the synthesis of nanoparticles. These were tested for antioxidant activity by DPPH assay.

Results: The present study shows that the antioxidant activity of Lawsonia Alba mediated silver nanoparticles was seen to be increased as the concentration increased in a dose-dependent manner, hence it can act as a good antioxidant.

Conclusion: Lawsonia Alba mediated silver nanoparticles were proved to possess a strong level of antioxidant activity. The results of  the  study reinforce the opinion that medicinal plants are promising sources of potent antioxidants that may be useful for therapy.
