Moringa oleifera is a plant that grows in tropical and subtropical areas of the world. Its leaves are rich of nutrients and bioactive compounds. However, several differences are reported in the literature. In this article we performed a nutritional characterization and a phenolic profiling of M. oleifera leaves grown in Chad, Sahrawi refugee camps, and Haiti. In addition, we investigated the pr...

Elaeocarpus floribundus is higher plant that has been used as traditional medicine for treating several diseases. There is no previous report on phytochemicals and bioactivity studies of this species. In this investigation, triterpenoids friedelin, epifriedelanol and β-sitosterol were isolated from its leaves and stem bark. Determination of total phenolic content of methanolic extract of leaves...

Cannabidiol (CBD) is a non-psychoactive cannabinoid compound found in hemp plants that has recently sparked interest the biomedical and food industries. CBD natural decarboxylated product of cannabidiolic acid (CBDA). In this study, processing parameters were developed to enhance decarboxylation process CBDA leaves using hot-melt extrusion (HME). The formulated with two different acid-based pol...

Increased consumption of vegetables or plant food has been associated with decreased risk of developing major chronic diseases, such as cancers, diabetes, cardiovascular diseases, and age-related functional decline. Ramie leaves are rich in phenolics and flavonoids, which have been suggested for human health benefits. Phenolic contents, flavonoid contents, phenolic compounds, and anti-cancer pr...

The present investigation was carried out to determine the antioxidant properties in methanolic extract of leaves, stem, fruit and roots of Physalis angulata (L). The antioxidant assay was carried out using free radicals DPPH, superoxide, nitric oxide, hydrogen peroxide and hydroxyl radical. Among the extracts tested fruit and leaf extracts were found to be significant in their antioxidant prop...

background & aim: nowdays consumers prefer to eat healthier foods, therefore producers and researchers are involved to improve the variety, quality, taste of food products. lemon balm is a perennial, aromatic, herb that contains many phenolic compounds. in this research the effect of additing lemon balm powder (by reducing of wheat flour in formulation, instead) on qualities of sponge cakes...

Phenolic acids in commercially important sweet potato cultivars grown in the United States were analyzed using reversed-phase high-performance liquid chromatography (HPLC). Caffeic acid, chlorogenic acid, 4,5-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid, and 3,4-di-O-caffeoylquinic acid were well separated with an isocratic elution in less than 25 min compared to about 120 min for ana...

mahaleb (prunus mahaleb l.) is an important rootstock for p. avium and p. cerasus cultivars. the present study has compared the phenolic contents and antioxidant activity of the methanolic extracts of the barks, leaves and fruits of ten selected mahaleb genotypes. the total phenolic content (5.11-131.77 mg ga g-1) in barks and the total flavonoid (54.06-180.6 mg qe g-1) and proanthocyanidin (8....

pomegranate tree possesses a vast ethnomedical history and represents a phytochemical reservoir of heuristic medicinal value. in the present study, total phenolics, antioxidant, and antibacterial activities of pomegranate peel were determined by folin–ciocalteu, 2,2-diphenyl-1-picrylhydrazyl (dpph) and disk-diffusion methods, respectively, and compared among the accessions. methanolic extract g...

Objective: In present study different extracts of the leaves of plant Casearia tomentosa was investigated for the phytochemical screening, total phenolic content and various pharmacological activities like antioxidant, antidiabetic, antibacterial. Methods: Leaves of C. tomentosa were successively extracted by soxhlet extraction method using petroleum ether, chloroform, ethyl acetate and ethanol...
