Essential oils from Hertia cheirifolia L. were evaluated for antioxidant activities by the 1,1-diphényl-2-picrylhydrazyl (DPPH), reducing power and carotene/linoleic acid and inhibitory properties against-glucosidase. The essential oils (EOs) have been analyzed by gas chromatography (GC) and gaschromatography–mass spectrometry (GC–MS). Chemical analyses showed that the EOs were rich interpenes. -Pinene was identified as major component in H. cheirifolia essential oils.Studies on kinetic behavior of the EOs showed that the oils of this species were non-competitiveinhibitors and the flowers oil exhibited a strong -glucosidase inhibitory activity with IC50value of0.24 ± 0.01 mg/mL.

Abstract
Essential oils from Hertia cheirifolia L. were evaluated for antioxidant activities by the 1,1-diphényl-2-picrylhydrazyl (DPPH), reducing power and carotene/linoleic acid and inhibitory properties against-glucosidase. The essential oils (EOs) have been analyzed by gas chromatography (GC) and gaschromatography–mass spectrometry (GC–MS). Chemical analyses showed that the EOs were rich interpenes. -Pinene was identified as major component in H. cheirifolia essential oils.Studies on kinetic behavior of the EOs showed that the oils of this species were non-competitiveinhibitors and the flowers oil exhibited a strong -glucosidase inhibitory activity with IC50value of0.24 ± 0.01 mg/mL. These results show that H. cheirifolia could be a natural source of potent antioxidantsand -glucosidase inhibitors.File | Dimensione | Formato | |
