Abstract:
Background: Oenanthe fistulosa L. (Apiaceae) is often associated with damp soils. Its
underground parts and the young leaves are mainly cooked with other vegetables.
Objective: The aim of the current work was to investigate the chemical profile of dichloromethane
(DCM), Ethyl Acetate (EA) and n-butanol (BuOH) fractions of O. fistulosa through analysis of 37
phytochemicals by LC-MS/MS and to evaluate their biological activities such as antioxidant, anticholinesterase
and antityrosinase for the first time.
Methods: Analysis of 37 phytochemicals was performed by Liquid Chromatography-Mass Spectrometry
(LC-MS/MS). Antioxidant activity was evaluated using five in vitro assays, while anticholinesterase
and anti-tyrosinase activities were performed using Ellman and Dopachrome methods,
respectively.
Results: The number of phenolic compounds detected in DCM, EA and BuOH fractions was found
to be 9, 15, and 12; respectively. More specifically, 9 phenolic acids were detected and among them,
chlorogenic, tr-ferulic and p-coumaric acids were the most abundant. While 8 flavonoids were detected
and apigetrin, rutin, and quercitrin were the most abundant. In addition, 3 non-phenolic organic
acids (quinic, malic and fumaric acids) were detected in large quantities. Furthermore, the tested
plant fractions demonstrated a noteworthy and strong antioxidant action. The plant displayed very
strong action against Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes; and
BuOH fraction was the most potent one. Finally, BuOH and DCM fractions showed good tyrosinase
inhibitory activity.
Conclusion: According to the obtained results, O. fistulosa might be a promising candidate for the
alleviation of oxidative stress, neurodegenerative (such as Alzheimer’s disease) and hyperpigmentation
disorders.
