“…Some of the compounds were identified by spiking experiments with available standards (rhamnetin, rhamnacin and sakuranetin). From the fifteen compounds tentatively identified in the Z. punctata decoction, three correspond to phenolic acid (2, 3, 7); seven flavones (4,6,8,9,10,11,12), one chalcone (5), two terpenes (13,16) and one fatty acid (14). Compound 5 (2 ,4 -dihydroxy-3 -methoxychalcone) is one of the two most characteristic chalcones of this species, which has been previously isolated and identified in extracts obtained from the aerial parts, fruits and resin with ethanol, methanol and dichloromethane [22,[25][26][27][28][29].…”

“…Root knots are the result of the feeding process and the habit of parasitism (endoparasite). The way in which they can ensure their nutrition throughout all their sedentary stages is by generating large cells, affecting the absorption functions of the roots [8]. Agrochemicals have had a major role in improving yields in food production.…”

This research was designed to investigate the metabolite profiling, phenolics, and flavonoids content as well as the potential nematicidal properties of decoction (ZpDe), orange-yellow resin (ZpRe) and essential oil (ZpEO) from Argentinean medicinal plant Zuccagnia punctata Cav. Additionally, the antioxidant and antibacterial properties of ZpDe and ZpEO were determined. Metabolite profiling was obtained by an ultrahigh-resolution liquid chromatography MS analysis (UHPLC-ESI-QTOF/OT-MS-MS) and GCMS. The nematicidal activity was assayed by a standardized method against Meloidogyne incognita. The antioxidant properties were screened by four methods: (2,2-diphenyl-1-picrylhydrazyl assay (DPPH), Trolox equivalent antioxidant activity assay (TEAC), ferric-reducing antioxidant power assay (FRAP), and lipid peroxidation in erythrocytes (ILP). The antibacterial activity was evaluated according to the Clinical and Laboratory Standards Institute (CLSI) rules. The ZpDe, ZpRe and ZpEO displayed a strong nematicidal activity with an LC50 of 0.208, 0.017 and 0.142 mg/mL, respectively. On the other hand, the ZpDe showed a strong DPPH scavenging activity (IC50 = 28.54 µg/mL); ILP of 87.75% at 250 µg ZpDe/mL and moderated antimicrobial activity. The ZpEO showed promising activity against a panel of yeasts Candida albicans and non-albicans (ATCC and clinically isolated) with MIC values from 750 to 1500 µg/mL. The ZpDe showed a content of phenolics and flavonoid compounds of 241 mg GAE/g and 10 mg EQ/g, respectively. Fifty phenolic compounds were identified in ZpDe by ultrahigh-resolution liquid chromatography (UHPLC–PDA– Q-TOF-MS) analysis, while forty-six phenolic compounds were identified in ZpRe by UHPLC-ESI-Q-OT-MS-MS and twenty-nine in ZpEO using a GC-MS analysis, updating the knowledge on the chemical profile of this species. The results support and standardize this medicinal plant mainly as a potential environmentally friendly and sustainable bionematicide for the control of Argentinean horticultural crops including tomatoes and peppers and as a source of antimicrobial and antioxidant compounds which could be further explored and exploited for potential applications.

El lulo (Solanum quitoense Lam.) es un frutal promisorio debido a su alta demanda y una alternativa para desarrollar cultivos a nivel empresarial; sin embargo, problemas fitosanitarios como Fusarium oxysporum limitan el potencial productivo de la especie y genera pérdidas económicas significativas a los agricultores. El objetivo de este trabajo fue evaluar 57 introducciones de lulo por su reacción a F. oxysporum y componentes de rendimiento. Las introducciones de lulo se sembraron en una localidad del municipio de La Florida, departamento de Nariño, Colombia, con historial de epidemias causadas por F. oxysporum. De cada introducción se sembraron cinco plantas a 2.5 m entre ellas y 3 m entre surcos. Las variables evaluadas se sometieron al Análisis de Componentes Principales y Clasificación Jerárquica. Para seleccionar las mejores introducciones se aplicó un índice de selección formado por variables de mayor importancia. Los primeros cuatro componentes principales explicaron el 82.4 % de la variación total. Según el Análisis de Clasificación, el primer grupo presentó los promedios más bajos en cuanto a mortalidad por F. oxysporum (MFo). El segundo grupo mostró niveles más altos de MFo y más bajos en los componentes de rendimiento. El tercer grupo se caracterizó por tener promedios superiores en los componentes de rendimiento y sólidos solubles totales (SST) y el grupo cuatro por el promedio más bajo de Neoleucinodes elegantalis. Las introducciones seleccionadas 15C, 22A, 37A y 35A se definieron por presentar los promedios más altos en rendimiento, peso de fruto, SST y por ser resistentes a F. oxysporum.
