Antioxidant and skin health-enhancing activities of wild indigo (Baptisia tinctoria) root extracts

This study aimed to investigate the effects of wild indigo (Baptisia tinctoria) root extract as a functional food material, in terms antioxidant and skin health-related activities. Both water ethanol (50/50, v/v) extracts showed high phenol content. They were evaluated for activity, such 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2?-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), protection factor (PF), thiobarbituric acid reactive substances (TBARS). While DPPH radical scavenging activities 84.23% 89.30%, respectively, at 200 ?g/mL total content (TPC), ABTS cation 51.39% 48.10%, respectively. The also desirable PF levels 1.18 1.16, Furthermore, on TBARS significantly increased by 37.31% 51.43%, extracts. dose-dependent collagenase inhibitory activities, up 27.60% 77.39%, an elastase activity 37.21%; tyrosinase effect (which facilitates natural skin-whitening) was 59.26% TPC. hyaluronidase inhibition, related anti-inflammatory 20.02% 14.30% extract, Therefore, B. tinctoria has potential applications cosmetics supplements due its health promoting
