Edible Rhus tripartita fruit as source of health-promoting compounds: characterization of bioactive components and antioxidant properties

Abstract

The fruits of Rhus tripartita had recently attracted great attention due to its notable therapeutic effects. Their potential effects are attributed to the richness of diverse classes of secondary metabolites. The objective of this research was to access the determination of chemical composition and antioxidant properties of R. tripartita fruit extracts and its partitioned fractions (absolute petroleum ether, 70% aqueous ethanol, absolute ethyl acetate and water). LC-ESI-MS/MS and FTIR-ATR were used to assess the potential of R. tripartita fruits as a source of health-promoting constituents. A total of 38 phenolics, including flavones, flavonols, flavanones, organic acids, hydroxycinnamic acids and hydroxybenzoic acids, 26 of them were reported for the first time in R. tripartita. The main compounds were apigenin7-O-glucoside, apigenin and p-coumaric acid. The FTIR-ATR analysis results revealed the presence of characteristic functional groups such as − OH, C-O, − C = C and C-H of phenolic compounds, carboxylic acids, carbohydrates, lipophilic components and proteins in R. tripartita fruits. Furthermore, the ethyl acetate fraction showed the highest level of phenolic contents and strong antioxidant activities. The present study recommends R. tripartita fruits as source of natural antioxidants which can be used as bioactive ingredient for functional foods and nutraceuticals.

Protective effect of leaf extract of Abutilon indicum on DNA damage and peripheral blood lymphocytes in combating the oxidative stress

“…The phenolic compounds found in Abutilon indicum are known as powerful chain-breaking antioxidants ( Das et al, 2019 ). Polyphenols are the major phytochemical constituents reported in Abutilon indicum that scavenge free radicals due to its hydroxyl group and may directly contribute to its antioxidative functions ( Tlili and Sarikurkcu, 2020 , Abcha et al, 2019 , Bendary et al, 2013 ). Furthermore, it suggests that polyphenols possess inhibitory effects on carcinogenesis and mutagenesis in humans ( Rybková et al, 2016 , Vitaglione and Fogliano, 2004 ).…”

Extraction of Phenolic Compounds From Fenugreek Seeds: Modelling and Analysis Using Artificial Neural Networks

“…AA of the samples were measured with DPPH radical scavenging activity method [25]. 50 µL of sample was mixed with 0.1 mM (prepared in ethanol) of 1.95 ml DPPH.…”

“…Extraction is a process in the recovery of bioactive compounds from natural sources. The extraction conditions depend on factors such as the extraction method to be used, solvent type, pH, temperature, sample-to-solvent ratio, and extraction time as well as the nature of the bioactive components to be extracted [25]. Therefore, it is necessary to know how these parameters affect the extraction efficiency in obtaining fenugreek seed extracts rich in phenolic compounds.…”

Phytochemical Analysis and Antioxidant Evaluation of the Ethanolic Extract of the Leaves of Abutilon indicum

“…These secondary metabolites not only serve as precursors and prototypes for drug development but also act as valuable pharmacological probes. They play a pivotal role in global drug discovery efforts and can even serve as foundational blueprints for the development of synthetic drugs or as essential building blocks for semisynthetic drug production [8].…”
