Antioxidative properties of isolated saponins of Verbesina encelioides (Cav.) Benth. & Hook. fil ex Gray and SEM studies of synthesized green nanoparticles for acne management

anti-acne, herbal formulationAbstract
Acne is one of the most common and chronic skin problems in most adolescents and young adults due to several internal and external factors. The present study emphasizes on screening of high antioxidant potential of wild sunflower for acne therapy, as it also plays a major role in the patho-physiology of acne. The anti-oxidant potential of extracted plant compounds was carried out by using 1, 1-diphenyl-2-picryl hydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). In recent years, scientists have been involved in the application of green nanoparticle synthesis. Further synthesized green nanoparticles were checked for antiacne potential. Isolated saponins and their synthesized nonolparticles would play an important role to control the acne.
