This study aimed to investigate for the first time the chemical composition, the antioxidant properties and the acetylcholinesterase (AChE)and butyrylcholinesterase (BChE) inhibitory activity of the essential oil from the leaves of Cordia gilletii De Wild (Boraginaceae). Theessential oil, characterized by 23 constituents (90.1% of the total oil), was constituted by terpene derivatives (25.6%) and non-terpenederivatives (64.5%), among which aldehydes, fatty acids and alkanes were present with the percentage of 16.5%, 18.8% and 23.1%,respectively. The antioxidant activity of C. gilletii essential oil was screened by two in vitro tests: DPPH and β-carotene bleaching test. Theessential oil revealed antioxidant activity with an IC50 value of 75.0 and 129.9 μg/mL on DPPH radical and β-carotene decoloration tests,respectively. Moreover, C. gilletii inhibited AChE enzyme with an IC50 value of 105.6 μg/mL.

Abstract
This study aimed to investigate for the first time the chemical composition, the antioxidant properties and the acetylcholinesterase (AChE)and butyrylcholinesterase (BChE) inhibitory activity of the essential oil from the leaves of Cordia gilletii De Wild (Boraginaceae). Theessential oil, characterized by 23 constituents (90.1% of the total oil), was constituted by terpene derivatives (25.6%) and non-terpenederivatives (64.5%), among which aldehydes, fatty acids and alkanes were present with the percentage of 16.5%, 18.8% and 23.1%,respectively. The antioxidant activity of C. gilletii essential oil was screened by two in vitro tests: DPPH and β-carotene bleaching test. Theessential oil revealed antioxidant activity with an IC50 value of 75.0 and 129.9 μg/mL on DPPH radical and β-carotene decoloration tests,respectively. Moreover, C. gilletii inhibited AChE enzyme with an IC50 value of 105.6 μg/mL.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
