    Ain Raal1,*, Linda Rusalepp2, Tatiana Chiru3, Nicolae Ciobanu3, Kelly Talvistu1, Michelle Shusta1, Oleh Koshovyi1,4, Tõnu Püssa2

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 2965-2979, 2023, DOI:10.32604/phyton.2023.042723

    Abstract The fruits of the Sea buckthorn (Hippophae rhamnoides L.) are a popular plant food and a valuable health product. Cultivating plants produces a lot of leaves with fine branches as an unnecessary residue, which needs valorization. The aim of the study was to estimate (by HPLC-MS/MS) the qualitative and quantitative content of polyphenolic compounds in different parts of H. rhamnoides (HR), and to determine the level of antioxidant activity of leaves and fruits (by DPPH, ABTS methods and ferrozine test). Up to 19 compounds were identified in different parts of HR. The fruits are rich in flavonoids, including various glycosides… More >

    In Vitro and in Silico Insights on the Biological Activities, Phenolic Compounds Composition of Hypericum perforatum L. Hairy Root Cultures

    Oliver Tusevski1,*, Marija Todorovska1, Jasmina Petreska Stanoeva2, Marina Stefova2, Sonja Gadzovska Simic1

    Phyton-International Journal of Experimental Botany, Vol.92, No.3, pp. 921-941, 2023, DOI:10.32604/phyton.2023.024995

    Abstract Three Hypericum perforatum hairy root lines (HR B, HR F and HR H) along with non-transformed roots were analyzed for phenolic compounds composition and in vitro enzyme inhibitory properties. In silico molecular modeling was performed to predict the interactions of the most representative phenolic compounds in HR clones with enzymes related to depression, neurodegeneration and diabetes. Chromatographic analyses revealed that HR clones represent an efficient source of quinic acid and hydroxybenzoic acids, epicatechin and procyanidin derivatives, quercetin and kaempferol glycosides, as well numerous xanthones. In vitro antidepressant activity of HR extracts through monoamine oxidase A (MAO-A) inhibition was attributed to… More >

    Abstract Phenolic compounds are related to high biological activity, avoiding oxidation in food and human systems. Nutshells are by-products derived from the pecan nut processing that contain important amounts of phenols which biological activity must be studied. This research aimed to evaluate the antioxidant (DPPH, ABTS, FRAP and hemolysis) and anti-inflammatory activities of shell extracts from pecan nuts harvested during the crop production cycle 2018 and 2019, as well as the in vitro digestibility of their phenolic compounds, including flavonoids. Results showed that extracts from the crop production cycle 2018 obtained the highest yield, while those from 2019 contained the highest… More > Graphic Abstract

    Sorghum: Nutritional Factors, Bioactive Compounds, Pharmaceutical and Application in Food Systems: A Review

    Heba I. Mohamed1,*, Eman M. Fawzi1, Abdul Basit2, Kaleemullah3, Rafiq Lone4, Mahmoud R. Sofy5

    Phyton-International Journal of Experimental Botany, Vol.91, No.7, pp. 1303-1325, 2022, DOI:10.32604/phyton.2022.020642

    Abstract After wheat, rice, maize, and barley, sorghum is the fifth most widely grown cereal on the planet. Due to its high production, drought resistance, and heat tolerance, this crop is replacing maize in some areas. Sorghum is available in a variety of colors, including cream, lemon-yellow, red, and even black. The principal grain anatomical components are pericarp, germ or embryo and endosperm. This review provides an overview of key sorghum grain components, including starches, fiber, proteins, lipids, and vitamins. Also, we summarized phenolic compounds, flavonoids, tannins, carotenoids, vitamin E, amines, Policosanols and Phytosterols in sorghum grains. Sorghum is used to… More >

    Comparison of Essential Oil Composition, Phenolic Compound and Biological Activities of Salvia microphylla and Teucrium polium (Lamiaceae)

    Ayda Khadhri1, Chedia Aouadhi2, Eric Masson3, Antonio Pizzi4,5,*

    Journal of Renewable Materials, Vol.10, No.6, pp. 1607-1621, 2022, DOI:10.32604/jrm.2022.018950

    Abstract Salvia microphylla and Teucrium polium are medicinal and aromatic plants with ethnobotanical uses. The present study was conducted to investigate the chemical composition of Salvia microphylla and Teucrium polium essential oils, the secondary metabolites, and the biological activities of their infusion and methanolic (MeOH) extracts. Essential oils were extracted by hydrodistillation from shoots Salvia microphylla and Teucrium polium. Phenolic content, antioxidant and antimicrobial activities were determined. Gas chromatography-mass spectrometry (GC-MS) results showed the presence of significant qualitative and quantitative variations for the composition of the both essential oils (EO). Salvia microphylla EO were most complex and present 70 compounds with… More >

    Identification of Phenolic Compounds from K. ivorensis by Selected Chromatographic and Spectrometric Techniques

    A. Bikoro Bi Athomo1,2, S. P. Engozogho Anris1,2, R. Safou Tchiama2,3, F. Eyma4, C. Arnaudguilhem5, B. Charrier1,*

    Journal of Renewable Materials, Vol.9, No.1, pp. 35-48, 2021, DOI:10.32604/jrm.2021.013626


    A complementary approach using Liquid Chromatographic-Mass Spectrometric analysis was proposed to characterize phenolic compounds from the methanol-water extracts of K. ivorensis A. Chev. Two High Performance Liquid Chromatography (HPLC) complementary methods were used for the determination of phenolic compounds from the bark, sapwood and heartwood of K. ivorensis. Methods employed involved direct analysis after filtration at 0.20 µm, using a RP C18 column and UV-VIS/ESI-FTMS detection. The methods used were different by their elution gradient and allowed analyzing the chemical composition of three parts of African mahogany extracts. In this study, 22 phenolic compounds and derivatives from K. ivorensis were… More >

    Phyton-International Journal of Experimental Botany, Vol.89, No.2, pp. 361-373, 2020, DOI:10.32604/phyton.2020.08499

    Abstract This work aims to determine the phytochemical characterization of the pericarp of Chamaedorea radicalis Mart. fruit as a non-timber product with potential to obtain phytochemicals with potential applications in the industry. Fruit from C. radicalis were grouped in four ripening stages named as S1, S2, S3 and S4, according to maturity; S1 the most unripe stage and S4 the completely ripe stage. Determinations of total phenolic compounds, free radical scavenging activities and total flavonoid contents using spectrophotometric methods were done. Also, the tentative identification of phytochemicals during fruit ripening was done using UPLC-MS-MS. Total phenolic compound (TPC) content ranged from… More >

    Effect of phenolic compounds present in Argentinian plant extracts on mycelial growth of the plant pathogen Botrytis cinerea Pers.

    Hapon MV1,2, JJ Boiteux1,2, MA Fernández1, G Lucero1,2, MF Silva1, PH Pizzuolo1,2

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 270-277, 2017, DOI:10.32604/phyton.2017.86.270

    Abstract The polyphagous plant pathogen Botrytis cinerea has the ability of growing fast under several conditions, and producing grey moulds in different plant tissues. Because of its adaptive plasticity, resistant strains have made difficult their chemical control. Therefore, new strategies of management and the use of natural compounds could be important control alternatives. The aim of this work was to study the potential value of four Argentine native plant extracts and some of its phenolic compounds as biodrugs on B. cinerea. Aqueous plant extracts of Larrea divaricata, Prosopis strombulifera, Tessaria absinthioides and Schinus molle var. areira, were used. The capability to… More >
