“…Chlorogenic acid (lower than 0.2 µg g −1 ) was also detected in the ethanolic extract of aerial parts of Chrysanthemum parthenium Bernh, very low value, compared to our results, probably due to a different solvent extraction [33]. A study regarding Bellis perennis L. revealed that a greater amount of chlorogenic and neochlorogenic acids were detected in leaves than in root; these compounds were studied for their allelopathic properties [34]. Derivatives of hydroxycinnamic acid, and particularly chlorogenic acid, are considered a characteristic trait of the Asteraceae plants, although they are ubiquitous of the plant kingdom [34,35].…”

Guayule (Parthenium argentatum) is one of the most promising alternatives to produce natural rubber. As the guayule leaves represent a waste byproduct in the rubber extraction process, their exploitation might contribute to the valorization of the whole plant biomass. The specific aim of our study was to determine the antioxidant capacity and the content of phenolic compounds in leaves and twigs of different guayule lines cultivated in a Mediterranean environment. The antioxidant capacity and the contents of phenolic were affected significantly by guayule accession and harvest time. Overall means in twigs represented about 60% of the corresponding leaf values for antioxidant capacity as DPPH (1,1-diphenyl-2-picrylhydrazyl) and not tannic phenolic and about 55% as ABTS (2,2′-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt), total phenolic, tannic phenolic and total flavonoid contents. Five individual phenolic compounds were identified in methanolic extracts of leaves. Neochlorogenic acid (62.5–174.8 mg g−1 DW) and chlorogenic acid (28.6–41.1 mg g−1 DW) were the most abundant phenolic acids. In addition to the compounds quantified in leaves, cynarin was identified only in twigs and for the first time in guayule biomass. Our results indicate that guayule leaves and twigs represent a rich source of antioxidants for potential applications in fodder, nutraceutical and pharmacological sectors.

“…1). Compounds 1-6 were identified as hydroxycinnamate based on the comparison with NMR data of compounds previously isolated from Bellis perennis (Scognamiglio et al, 2012b). In particular, compound 1 was identified as caffeic acid, while compounds 2 and 3 were identified as chlorogenic and neochlorogenic acid, respectively.…”

“…Concerning the other selective extract, B. sylvestris , the response of the target plants to it was different from the response to the other extracts and it was also species‐specific for the receiving plant. For this extract, the univocal identification of active metabolites was not possible, due to the presence of hydroxycinnamates and saponins, both reported to influence plant growth . In the future, further studies will be carried out with pure compounds and/or their mixtures in an attempt to identify the active principles or to demonstrate their synergism.…”

Introduction Mediterranean plants are characterised by a high content of bioactive secondary metabolites that play important roles in plant–plant interactions as plant growth regulators and could be useful for the development of new eco‐friendly herbicides. Objective An NMR‐based metabolomics approach was reported to seek selective phytotoxic plant extracts and putative plant‐derived active molecules. Methods Plant extracts derived from five Mediterranean donor species (Pistacia lentiscus, Bellis sylvestris, Phleum subulatum, Petrohrhagia saxifraga and Melilotus neapolitana) were used to treat the hydroponic cultures of three receiving plants (Triticum durum, Triticum ovatum and Avena fatua). Morphological analyses of the treated receiving plants were carried out. NMR‐based metabolomics was applied both to characterise the donor plant extracts and to study the effects of the treatments on the receiving plants. Results This study allowed the identification of Melilotus neapolitana and Bellis sylvestris as phytotoxic plant and good candidates for further studies. Specifically, the NMR‐based metabolomics investigation showed that these species affect a specific set of metabolites (such as sugars, amino and organic acids) and therefore metabolic pathways [i.e. tricarboxylic acid (TCA) cycle, amino acid metabolism, etc.] that are crucial for the plant growth and development. Moreover, it was possible to identify the metabolite(s) probably responsible for the phytotoxicity of the active extracts. Conclusion The NMR‐based metabolomics approach employed in this study led to the identification of two phytotoxic plant extracts and their putative active principles. These new insights will be of paramount importance in the future to find plant derived molecules endowed with phytotoxic activities.
