In the present study, we aimed to search and compare the biological activities of the ethanol (EtOH), methanol (MeOH), and ethylacetate (EtOAc) solvent extracts of the flower, stem, and root parts of two Helichrysum plants (H. chionophilum (Hc) and H. plicatum subsp. plicatum (Hp)). The antioxidant properties were determined by using (2,2‐diphenyl‐1‐picrylhydrazyl) (DPPH) and ABTS (2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic...
Salicylic acid (SA) is one of the important signal molecules modulating plant responses to environmental stress. In this study, the effects of exogenous SA on leaf rolling, one of drought avoidance mechanisms, and antioxidant system were investigated in Ctenanthe setosa during long term drought stress. The plants were subjected to 38-day drought period and they were treated with or without SA (10−6...
