Antioxidant Capacities and Enzymatic Inhibitory Effects of Different Solvent Fractions and Major Flavones from Celery Seeds Produced in Different Geographic Areas in China

Abstract

To extend the application of celery (Apium graveolens L.) seeds, the antioxidant and enzymatic inhibitory activities of different fractions and their main flavones were investigated. The n-butanol fractions possessed the highest total phenolic content (TPC) and total flavonoid content (TFC) values. The n-butanol fractions from Northeast China samples exhibited the strongest free radical scavenging (DPPH IC50 = 20.27 μg/mL, ABTS IC50 = 15.11 μg/mL) and ferric reducing antioxidant power (FRAP 547.93 mg trolox (TE)/g) capacity, while those collected from Hubei China showed the optimal cupric reducing antioxidant capacity (CUPRAC) values (465.78 mg TE/g). In addition, the dichloromethane fractions from Jiangsu samples displayed a maximum Fe2+ chelating capacity (20.81 mg ethylene diamine tetraacetic acid (EDTA)/g). Enzyme level experiments indicated polyphenolic compounds might be the main hypoglycemic active components. Subsequently, the enzyme inhibitory activity of nine main flavones was evaluated. Chrysoeriol-7-O-glucoside showed better α-glucosidase inhibitory activity than others. However, apigenin showed the best inhibitory effect on α-amylases, while the presence of glycosides would reduce its inhibitory effect. This study is the first scientific report on the enzymatic inhibitory activity, molecular docking, and antioxidant capacity of celery seed constituents, providing a basis for treating or preventing oxidative stress-related diseases and hyperglycemia.

Anti-Cryptosporidium parvum activity of Artemisia judaica L. and its fractions: in vitro and in vivo assays

“…They comprise stilbenes, tannins, coumarins, phenolic acids and flavonoids ( Abotaleb et al, 2019 ). Polyphenols are natural antioxidants in fruits and vegetables ( Abotaleb et al, 2019 ; Zhang et al, 2022 ). The most predominant polyphenolic compounds in the plant kingdom are phenolic acids and flavonoids ( Chen et al, 2022 ).…”

“…The most predominant polyphenolic compounds in the plant kingdom are phenolic acids and flavonoids ( Chen et al, 2022 ). In recent years, plant polyphenols have received increasing attention and drawn much interest due to their diverse biological activities ( Zhang et al, 2022 ), including antiprotozoal activities ( Phillipson and Wright, 1991 ). Therefore, In the current study, the total phenolics, flavonoids contents in A. judaica were quantified.…”
