Phenol content, antioxidant capacity and antibacterial activity of methanolic extracts derived from four Jordanian medicinal plants.
Following that, the extracts were centrifuged at rpm for 30 minutes. Occurrences in fungi[ edit ] Phenolic acids can be found in mushroom basidiomycetes species. Liver-protective effects of hydroalcoholic extract of Allium hirtifolium boiss.
On the other hand, S. Pomegranate arils are rich in anthocyanins, which are the source of the red pigment of the fruit, the dominant anthocyanins include cyanidinO-glucoside, cyanidin-3,5-di-O-glucoside, delphinidin O-glucoside, delphinidin-3,5-di-O-glucoside, pelargonidinOglucoside, and pelargonidin-3,5-di-O-glucoside [ 16 ].
These natural plant phenolics from Moringa seeds could be a good source of antioxidants and antibacterials for food and pharmaceutical industries. A volume of 2. Tracking color and pigment changes in anthocyanin products.
Determination of antioxidant and antimicrobial activities of Rumex crispus L. By the way, C. J Agric Food Chem.
Finally floral buds were rinsed with sterilized distilled water three times under laminar flow hood. In conclusion, these plants are not only interesting sources for antimicrobial agents but also have a considerable amount of antioxidants.
Plants Material and Sterilization Floral buds were collected in March from Crataegus azarolus var. However, there was significant difference in TPC among three species, S.
On the other hand, the skins and seeds of red grapes are fermented with the juice, so that extractable components wind up in the red wine. Chemical composition and antimicrobial activity of the essential oil of ferulago bernarda tomk and m.
Pharmaceutical Biology, 52 2: Antibacterial, antioxidant, extract, grape pomace, phenolic compounds, variety Introduction Grape pomace refers to the solid remains following pressing of grapes for juice or winemaking, and consists primarily of the skin, pulp, seeds, and stems.
Jul 09, Abstract Rind and aril of pomegranate Punica granatum were freeze-dried and extracted using solvents of varying polarity: Determination of total phenolic content To 0. Occurrences in lichen[ edit ] Gyrophoric acida depsideand orcinol are found in lichen. In present work, S. The rind and aril were then dried by freeze drying to conserve the phytochemical component present in them as water is sublimed from solid state directly to gaseous state without going through the liquid state at which liquid water acts as a medium for many chemical reactions which if occur, may affect the nature of the phytochemicals.
Triplicate tests were done for each sample. These results may provide certain basis on the preservation and use of these three Chinese medicinal plants for us to some extent. Screening of 70 medicinal plant extracts for antioxidant capacity and total phenols. Total phenols, total flavonoids, and total proanthocyanidins production by Crataegus azarolus var.
Methanol was used in the place of antioxidant solution as a blank. Results of above three radical scavenging assays demonstrated that extracts of these three plants exhibited relatively strong radical scavenging activities, and can serve as effective radical scavenger.
Antioxidant activity of Nigella sativa essential oil. The AlCl3 test for flavonoids does not measure those flavonoids that do not bear the characteristic chelating functional groups for Al binding Park et al.
Broth dilution and disc diffusion assays were performed to measure the antibacterial activity of these extracts against available bacterial strains. Statistical analyses Three replications of all assays were used to calculate means and standard deviations.
The test was performed in triplicate. The antioxidant properties are commonly postulated to play an important role in preventing diseases caused by oxidative stress, such as cancer, coronary arteriosclerosis, and the ageing processes [ 1 ]. Antioxidant activity of anti-flammatory plant extracts.
The HPLC analysis of individual compounds Table 1 shows a relation between the respective yields in the major catechin produced: Extraction of phenolics from citrus peels: This article has been cited by other articles in PMC.
Medicinal studies comprised of evaluating the antioxidant, antidiabetic and antibacterial potential of the prepared extracts.Total polyphenol content and antioxidant activities were evaluated for these five BFA propolis extracts using respectively Folin-Ciocalteu, 2,2-diPhenylPicrylHydrazyl (DPPH) and Oxygen Radical Absorbance Capacity (ORAC) assays.
Results and discussion: All extracts of BFA French propolis exhibited phenolic acids and esters as well as. Abstract. The phenolic composition and antibacterial and antioxidant activities of the green alga Ulva rigida collected monthly for 12 months were investigated.
Significant differences in antibacterial activity were observed during the year with the highest inhibitory effect in. In the present study, phenolic composition, antibacterial activity and antioxidant capacity of selected Brassica vegetables, including York cabbage, Brussels sprouts, broccoli and white cabbage were evaluated after extraction with aqueous methanol.
A comparison in terms of antioxidant capacity was made between different salads, as well as between salads to which aromatic herbs had been added. Lemon balm and marjoram at a concentration of 1·5 % w/w increased by % and % respectively the antioxidant capacity of a salad portion.
In the present study, we investigated the phenolic composition, antioxidant, antimicrobial and cytotoxic activities of ethanolic extracts from leaves and stems of leek (Allium porrum L.), which are growing in Central Serbia (Balkan) and is used in everyday human food.
Rosa damascena Mill. is one of the most important Rosa species for the flavour and fragrance industries. The high amount of residues of spent flowers after steam distillation and the potential use of their essential oils as natural antioxidants and antimicrobials lead to determine the antioxidant and antibacterial activities of fresh and spent Rosa damascena flower extracts.Download
