Comparative Volatile Profiling of Ludwigia stolonifera Aerial Parts and Roots Using VSE-GC-MS/MS and Screening of Antioxidant and Metal Chelation Activities

Abstract

Ludwigia stolonifera (Guill. & Perr.) P.H.Raven belonging to the family Onagraceae is an important aquatic herbal plant of economic importance in water bioremediation. We explored the compositional heterogeneity in the aroma profile of L. stolonifera aerial parts and roots. Volatile profiling was employed for the first time using volatile solvent extraction (VSE-GC-MS/MS) of both aerial parts and roots. A total of 85 volatiles were identified belonging to eight classes, viz., aliphatic, aromatic, and oxygenated hydrocarbons, monoterpenes, diterpenes, alcohols, acids/esters, and sterols. Aliphatic and aromatic hydrocarbons were found to be the most abundant metabolite groups in both aerial parts and roots. Furthermore, antioxidant and metal chelation activities of aerial parts and roots were investigated, revealing a potent activity as an antioxidant and high metal chelation capacity for heavy metals.

Phytochemical investigation of the n-hexane-extracted oil from four umbelliferous vegetables using GC/MS analysis in the context of antibacterial activity

“…2 ). Phenyl-undecane derivatives, a group of aromatic hydrocarbons with antifungal and antibacterial activities were reported at higher levels in green vegetables 23 . The most abundant aromatic detected in all vegetables was 2-phenylundecane (peak 77) which amounted to 6.3, 5.3, 6.2, and 5.7% in parsley, dill, celery, and coriander, respectively.…”

“…Gas chromatography coupled with mass spectrometry (GC–MS) analysis is a well-established analytical technique adopted for profiling volatile components in dietary sources 21 , 22 . Several methods are used for the extraction of volatile metabolites from plant materials including steam distillation, headspace solid phase microextraction (HS-SPME), supercritical fluid extraction, and volatile solvent extractions 23 , 24 . Compared to thermal-dependent distillation techniques, volatile solvent is applied to extract volatile compounds from plant samples without decomposition and increase the extract yield 23 .…”

Phytochemical Analysis and Profiling of Antitumor Compounds of Leaves and Stems of Calystegia silvatica (Kit.) Griseb.

“…The nonadec-1-ene is an essential oil that has not been evaluated for antitumor properties; however, it has been reported to display antimicrobial and antioxidant activity [ 53 ]. The alkane hydrocarbons methyl undecane, methyl dodecane and the benzenes 2-phenyl decane, 6-phenyl decane, 7-phenyl eicosane, phenyl undecane and 2-phenyl tridecane have not been evaluated for biological activities; however, methyl undecane has been reported to have anti-inflammatory properties [ 54 ]. Additionally, some compounds identified in the n -hexane extract that have not been evaluated for biological activities until now are the fatty acid octadecenoic acid, 12 hydroxy, methyl ester, the triterpenoid lanostan-3-ylacetate and the oxygenated sesquiterpenes longifolenaldehyde.…”

How Does Allium Leafy Parts Metabolome Differ in Context to Edible or Inedible Taxa? Case Study in Seven Allium Species as Analyzed Using MS-Based Metabolomics

“…4.5%. Phytol is characterized by its pleasant aroma and myriad biological activities [ 41 ], aside from serving as a precursor of vitamin E and contributing to its antioxidant effect. Further analysis of vitamin E levels would provide further evidence of such effects among Alliums based on that aroma profile using other techniques.…”
