“…The TEAC results are in agreement with the DPPH values, showing that N. damascena seeds exhibit a significantly higher antioxidant effect. Higher values for the IC 50 (IC 50 = 475 µg∙mL −1 ) were reported by Ratz-Lyco et al ., in a 50% aqueous-ethanolic extract, suggesting lower antioxidant activity [29]. Concerning the ferric reducing ability, there were some changes in the ranking order, the black cumin seeds presented a better antioxidant capacity than the lady-in-a-mist seeds.…”

Abstract:This study was performed to evaluate the phenolic profile, antioxidant and diuretic effects of black cumin and lady-in-a-mist seeds. In the phenolic profile, differences between the two species are significant. Qualitative and quantitative analyses of the phenolic compounds were performed using a HPLC-UV/MS method. Hyperoside was the only identified flavonoid glycoside (1.08 ± 0.01 μg·g dw plant material). The antioxidant potential of the two species was tested through several electron transfer assays, which indicated, excepting for the FRAP assay, N. damascena as exhibiting a higher free radical scavenging activity. The diuretic activity of the two extracts was tested using a rat-experimental model on acute diuresis. Administration of the ethanolic extract of N. sativa (100 mg·kg −1 ) resulted in a significant increase in urine volume, although less than found with the reference drug; in OPEN ACCESSMolecules 2015, 20 9561 addition N. damascena extract did not present a diuretic effect. In reference to the elimination of Na + , K + and uric acid, the black cumin extract exhibited a higher natriuretic than kaluretic effect and a similar uricosuric effect with control and N. damascena. For N. damascena, the Na + /K + ratio was sub unitary, but not due to an increasing of the kaluretic effect, but mostly to a decrease of Na + excretion.

“…Phytosterols present in primrose have also been shown to have antimicrobial and anti-inflammatory abilities [ 65 ]. Previous studies have demonstrated the high antimicrobial ability of the extracts and essential oil of primrose against different microorganisms such as S. aureus , and E. coli [ 267 , 271 , 272 ]. Recently, the methanolic and aqueous extracts of primrose have been shown to possess a high antibacterial effect against enterobacteria [ 273 ].…”

Antioxidant, Antimicrobial and Antiviral Properties of Herbal Materials

Recently, increasing public concern about hygiene has been driving many studies to investigate antimicrobial and antiviral agents. However, the use of any antimicrobial agents must be limited due to their possible toxic or harmful effects. In recent years, due to previous antibiotics’ lesser side effects, the use of herbal materials instead of synthetic or chemical drugs is increasing. Herbal materials are found in medicines. Herbs can be used in the form of plant extracts or as their active components. Furthermore, most of the world’s populations used herbal materials due to their strong antimicrobial properties and primary healthcare benefits. For example, herbs are an excellent material to replace nanosilver as an antibiotic and antiviral agent. The use of nanosilver involves an ROS-mediated mechanism that might lead to oxidative stress-related cancer, cytotoxicity, and heart diseases. Oxidative stress further leads to increased ROS production and also delays the cellular processes involved in wound healing. Therefore, existing antibiotic drugs can be replaced with biomaterials such as herbal medicine with high antimicrobial, antiviral, and antioxidant activity. This review paper highlights the antibacterial, antiviral, and radical scavenger (antioxidant) properties of herbal materials. Antimicrobial activity, radical scavenger ability, the potential for antimicrobial, antiviral, and anticancer agents, and efficacy in eliminating bacteria and viruses and scavenging free radicals in herbal materials are discussed in this review. The presented herbal antimicrobial agents in this review include clove, portulaca, tribulus, eryngium, cinnamon, turmeric, ginger, thyme, pennyroyal, mint, fennel, chamomile, burdock, eucalyptus, primrose, lemon balm, mallow, and garlic, which are all summarized.

“…Especies de plantas consideradas como malezas, tal como B. officinalis, son ampliamente utilizadas con fines medicinales y culinarios, entre los que resaltan como una fuente rica de ácido gamma linoleico, precursor de prostaglandinas antiinflamatorias; además, de poseer actividad antioxidante laxante, emoliente diurético entre otros (Galle et al 1993, Ratz-Łyko et al 2014, Fernandes et al 2019. Diversos estudios sobre las propiedades fitoquímicas de B. officinalis también han identificado la presencia de actividad antimicrobiana frente a diversos patógenos de interés (Mhamdi et al 2009, Arévalo 2009, Nieto-Navarro 2012, Basar et al 2013, Miceli et al 2014, Ávila 2016.…”

Introducción. Fusarium sp y Alternaria sp son hongos fitopatógenos que causan serios problemas en cultivos y en el sector agrícola, situación que genera pérdidas económicas importantes. Además, debido a la producción de micotoxinas representan una amenaza para la salud de los consumidores y para las plantas. Objetivo. Evaluar la actividad antifúngica del extracto etanólico de hojas de borraja (Borago officinalis) sobre Fusarium sp y Alternaria sp. Materiales y métodos. Se realizó la identificación cualitativa y cuantitativa de los metabolitos secundarios presentes en el extracto etanólico de B. officinalis, posteriormente, Fusarium sp y Alternaria sp. fueron secuenciadas por estudios moleculares mediante la amplificación de la región ITS (espaciador transcribible interno) del ADN ribosomal y finalmente, se evaluó la actividad antifúngica del extracto sobre las cepas previamente reconocidas mediante la prueba de crecimiento radial por técnica de difusión en agar. Resultados. El extracto etanólico de las hojas de B. officinalis contiene alcaloides, flavonoides, fenoles, olifenoles y saponinas, de los cuales los polifenoles y los flavonoides presentan una concentración de 19,08±0,01 miligramos equivalentes de ácido gálico (EAG) por gramo de extracto y 28,12±0,06 miligramos equivalentes de catequina (Qe) por gramo de extracto, respectivamente. La secuenciación de los aislamientos evaluados mostró una alta similitud (>98%) con varias especies de Fusarium sp y Alternaria sp, mientras que los ensayos de actividad antifúngica del extracto mostraron actividad fungistática por parte de B. officinalis al ser 16 mg.l-1 el tratamiento más efectivo para ambos aislamientos evaluados con un porcentaje de inhibición de 90,3±0,9% para Alternaria sp y 86,6±2,2% para Fusarium sp, donde Alternaria sp presentó mayor susceptibilidad frente al extracto de las hojas de B. officinalis. Conclusión. Los resultados de esta investigación proporcionan uno de los primeros reportes de la actividad antifúngica de Borago officinalis sobre Fusarium sp y Alternaria sp.
