New bioactive compounds characterized by liquid chromatography–mass spectrometry and gas chromatography–mass spectrometry in hydro‐methanol and petroleum ether extracts of Prosopis farcta (Banks & Sol.) J. F. Macbr weed

Abstract

The purpose of this study was to identify and characterize the chemical composition present in aerial parts of Prosopis farcta in petroleum ether and hydro-methanol extracts through LC-PDA-ESI-MS/MS and GC-MS techniques respectively for the first time. The plant samples were collected from northeast of Iran during maturity stage. LC-MS/MS profile revealed 47 phenolic compounds in hydro-methanol extracts, including phenolic acids, flavonoids, and their glycoside derivatives.Flavonoid-O-glycosides ( 19), flavonoid aglycones (11), phenolic acid derivatives (9), flavonoid-C-glycosides (4), and flavonoid-O, C-glycosides (1) were dominant class phenolics in all studied parts. The extracts contained a significant amount of major compounds, including gallic and vanillic acids, luteolin, apigenin, phloridzin, and vicenin-2. Also, GC-MS analysis of petroleum ether extracts showed that fatty acids, organic acids, steroids, terpenoids, and hydrocarbons were the group of major compounds in all parts. Twenty-four, 27, and 25 components were identified, which represent 99.2%, 96.1%, and 99.4% of the total composition in fruits, leaves, and stems, respectively. These results suggested that other genetic resources of P. farcta can be further explored to screen genotypes with high bioactive compounds and purification of phytochemical compounds, which are valuable to produce, expand, and develop natural antioxidants in production of bio-medicine and food.

Crataegus pentagyna willd. Fruits, leaves and roots: phytochemicals, antioxidant and antimicrobial potentials

“…MS detection utilized an ionization energy of 70 eV and a mass range of 50–550 m / z . By comparing their mass fragmentation patterns and retention times with the Wiley 7.0 and NIST libraries, the compound profiles were identified in petroleum ether extracts [ 28 , 29 ].…”

Multiobjective response and chemometric approaches to enhance the phytochemicals and biological activities of beetroot leaves: an unexploited organic waste

“…Nevertheless, the literature displayed that this unexploited biomass has been reviewed as a good source of bioactive compounds including proteins [11], minerals [12], and multiple phytochemicals [13] with biomedical applications [14][15][16]. Among beetroot leaf (BL) phytochemicals, the flavonoid glycosides acquired from apigenin, termed vitexin (such as vitexin-2-Orhamnoside and vitexin-2-O-xyloside), which is analyzed with liquid chromatography-mass spectrometry [17], could be reliable for the inhibition of α-glucosidase activity and therefore arbitrate this hypoglycemic effect [18]. Lorizola et al [18] confirmed that BL rich in vitexin derivatives can protect the liver from damage induced by a high-fat diet [19].…”
