“…The most detailed studies so far are those by Moiteiro et al, Marques et al,Mantzouris et al and Otłowska et al [24,26,28,34]. In contrast, the study by Burger is confusing with the major peaks reported as unknown [35]. Further, it is unclear where exactly luteolin-4 -O-glucoside elutes.…”

Detailed knowledge on natural dyes is important for agronomy and quality control as well as the fastness, stability, and analysis of dyed textiles. Weld (Reseda luteola L.), which is a source of flavone-based yellow dye, is the focus of this study. One aim was to reduce the required amount of dyed textile to ≤50 μg for a successful chromatographic analysis. The second aim was to unambiguously confirm the identity of all weld flavones. By carrying out the extraction of 50 μg dyed wool with 25 μL of solvent and analysis by reversed-phase UHPLC at 345 nm, reproducible chromatographic fingerprints could be obtained with good signal to noise ratios. Ten baseline separated peaks with relative areas ≥1% were separated in 6 min. Through repeated polyamide column chromatography and prepHPLC, the compounds corresponding with the fingerprint peaks were purified from dried weld. Each was unequivocally identified, including the position and configuration of attached sugars, by means of 1D and 2D NMR and high-resolution MS. Apigenin-4′-O-glucoside and luteolin-4′-O-glucoside were additionally identified as two trace flavones co-eluting with other flavone glucosides, the former for the first time in weld. The microextraction might be extended to other used dye plants, thus reducing the required amount of precious historical textiles.

“…Para S. zeamais, también presentaron buenos resultados los extractos en alcohol de N. glauca, P. clandestinum y R. luteola, al ocasionar más del 42 % de mortalidad en este insecto. Este efecto de la Gualda (R. luteola) está relacionado con sus metabolitos secundarios que contienen azufre y nitrógeno (Burger et al 2017). En P. truncatus, dos de los extractos en alcohol, presentaron resultados sobresalientes al ocasionar una mortalidad de 62.5 % (R. luteola) y 50 % (S. ballotiflora); así como los extractos alcohólicos de N. glauca y P. clandestinum, que causaron más del 40 % de mortalidad (Tabla 2).…”

“…For S. zeamais, alcohol extracts of N. glauca, P. clandestinum, and R. luteola also presented worthy performance, causing more than 42 % mortality in this insect. This effect of Gualda (R. luteola) is related to its secondary metabolites containing sulfur and nitrogen (Burger et al 2017). In P. truncatus, two of the extracts in alcohol presented outstanding results by causing mortality of 62.5 % (R. luteola) and 50 % (S. ballotiflora); as well as the alcoholic extracts of N. glauca and P. clandestinum, which caused more than 40 % mortality (Table 2).…”

El objetivo de esta investigación fue evaluar en condiciones de laboratorio el efecto de extractos de plantas asociadas al cultivo del maíz, para el control de Sitophilus zeamais (Coleoptera: Curculionidae) y Prostephanus truncatus (Coleoptera: Bostrichidae) en granos de maíz almacenado. Para los extractos etanólicos y por infusión se emplearon plantas completas en la mayoría de los casos. Para seleccionar los mejores extractos vegetales para el control de estas plagas, primero se realizaron pruebas de olfatometría, posteriormente se efectuó el experimento de laboratorio, impregnando granos de maíz almacenado en un diseño completamente aleatorio con 10 tratamientos y aplicaciones a las 24, 48 y 72 h. Los principales resultados mostraron que para S. zeamais la mayor mortalidad la produjo la infusión de Bromus cathartiucus 57.5%) seguido por el extracto etanólico de tabaquillo Nicotiana glauca (47.5%). En el caso de P. truncatus también el extracto en infusión de B. catharticus produjo un 70% de mortalidad y un 62.5% con el extracto etanolico de Reseda luteola. De acuerdo con estos resultados, los extractos de estas plantas podrían usarse para el control de S. zeamais y P. truncatus en un programa de manejo ecológico de plagas de maíz almacenado.

ObjectiveProsopis juliflora, commonly known as algaroba or mesquite, was introduced and has since proliferated throughout the semi‐arid region of the Caatinga biome. Various studies have documented its properties, including antimicrobial, antioxidant, and antitumor activities, attributed to the presence of diverse secondary metabolites such as alkaloids, terpenoids, tannins, and flavonoids. The objective of this study was to evaluate the antioxidant and antityrosinase activities of P. juliflora fruit extract as a multifunctional active ingredient, and to develop cosmetic formulations containing this vegetal extract for potential applications in skincare products targeting pro‐ageing and skin colour homogenization properties.MethodsThe extraction process followed established protocols. Chemical characterization of the extract involved quantification of total flavonoids and phenolic compounds, along with Liquid Chromatography‐Mass Spectrometry (LC–MS) analysis. In vitro antioxidant activity was assessed using different methods. Antityrosinase activity was determined by employing enzymatic assays. Cosmetic formulations containing Disodium EDTA, Phenoxyethanol (and) Ethylhexyl Glycerin, Distilled Water, Sodium Acrylates Copolymer Lecithin, Polyacrylamide (and) C13–14 Isoparaffin (and) Laureth‐7, and 3.0% of the investigated plant extract were subjected to preliminary and accelerated stability tests.ResultsThe extract demonstrated a concentration of total flavonoids (1.71 ± 0.26 μg EQ/mg) and exhibited concentrations of phenolic compounds at 0.21 ± 0.01 mg EAG/g. Metabolites such as flavonoids and saponins were annotated, as well as some of their respective glycosidic derivatives. The extract showed antioxidant potential and the ability to inhibit the oxidation cascade in both the initiation and propagation phases. Moreover, the extract exhibited noteworthy inhibition of antityrosinase activity, presenting 62.48 ± 2.09 at a concentration of 30.00 mg/mL. The formulations were stable in accelerated stability tests over a 60‐day period.ConclusionThis research not only demonstrates scientifically by demonstrating the potential of a plant from the Caatinga biome with antioxidant and antityrosinase properties in the development of cosmetic products aimed at pro‐ageing effects and skin colour harmonization, but also adds value to the P. juliflora production chain. This valorization encompasses various aspects which include environmental, social, and biodiversity responsibilities.
