• Total phenolic and flavonoid contents of extracts were analyzed. Total phenolic, total flavonoid content, and antioxidant capacity of the leaves of Meyna spinosa Roxb., an Indian medicinal plant. Dioscorea bulbifera showed the highest phenolic content … High correlations between antioxidant capacity and total phenols (DPPH, R 2 = 0.75; H 2 O 2 , R 2 = 0.71) and total flavonoids (DPPH, R 2 = 0.84; H 2 O 2 , R 2 = 0.66) were observed at a 95% confidence level.
The phenolics and flavonoids content of 20 medicinal plants were determined in the present investigation.
The aluminum chloride colorimetric method is used for the determination of the total flavonoid content of the sample. (Syn. Phenolic compounds contribute to the antioxidant potential of plants by neutralizing free radicals and preventing decomposition of hydroperoxides into free radicals34 2 and roots extracts, .
The total Phenolic content of the extracts was determined spectrophotometrically according to the Folin-Ciocalteau procedure and ranged from 366 mg/100g to 212 mg/100g on fresh weight basis. Among the leafy vegetables, the highest phenolic content was found in chard (57.73 mg GAE/g dry wt., in FG and 53.45 GAE/g dry weight in AG) followed by basil, red kale, and parsley. Total phenolic content of the 56 selected plants were measured using the Folin-Ciocalteu method, and the results are shown in Table 1.As seen from Table 1, the total phenolic content of these plants ranged from 0.12 to 59.43 mg GAE/g, with large differences between the plants of up to 495-fold. • Extracts were evaluated for their free radical scavenging and enzyme inhibitory activities. Six medicinal plants from Sudan were extracted with solvents of different polarity. There was a strong correlation between antioxidant activity with total phenolic (DPPH, R2 = 0.75; H2O2, R2 = 0.71) and total flavonoid content (DPPH, R2 = 0.84; H2O2, R2 = 0.66).
The antioxidant activity of the extracts was assessed using 2, 2-diphenylpicryl-1-hydrazyl (DPPH) free
This study demonstrates that these wild edible leafy plants could be a potential source of natural antioxidants. Determination of Total Phenolic Content. Figure 1 shows the total phenolic content in the samples of different leafy vegetable and fruit crops grown in Tower Garden aeroponic systems and in the soil. Antioxidant activity, total phenolic and flavonoid contents of selected medicinal plants used for liver diseases and its classification with chemometrics Harto Widodo 1,2, Sismindari Sismindari3, Widya Asmara 4, Abdul Rohman 3,5* 1Centre Study of Biotechnology, … The total phenolic content in the extracts was determined using Folin-Ciocalteu reagent and their amounts ranged between 8.33 to 169.06 mg GA/g. highest total phenolic content with 87.458 and 72.9644 mg GAE/g DW respectively. Cytisus triflorus L’Hérit.). Botanical insecticides that degrade rapidly are safer than persistent synthetic chemical insecticides, less harmful to the environment, decrease production costs and are not likely to cause insecticide resistance among pests. The correlation of total phenolic and flavonoid content with antioxidant capacity is shown in Figure 5 a,b. The concentrations of flavonoids in plant extracts varied from 3.96 to 88.31
The total flavonoids were measured spectrophotometrically by using the aluminium chloride colorimetric assay. In the other studies from different regions, the total phenolic content and flavonoid content of these plants have The aim of this study was to evaluate the total phenolic and flavonoid content, and the in vitro antioxidant, anti-inflammatory, antibacterial, antifungal, antimalarial, cytotoxicity, and antiprotozoal activities of the Algerian plant Cytisus villosus Pourr. 2.3.
This study demonstrates that these wild edible leafy plants could be a potential source of natural antioxidants. Total Phenolic Content. total flavonoid and total phenolic content from selected Kenyan medicinal plants, sea algae and mushrooms. Sen S(1), De B, Devanna N, Chakraborty R. Author information: (1)Department of Pharmacology, Creative Educational Society's College of Pharmacy, Kurnool 518218, Andhra Pradesh, India. The total phenolic content was high in H. hemerocallidea which had 0.268 0.02 mg/100mg dry mass of plant extract and lowest in E. muticus root extract had 0.041 … Total Phenolic Content Phenolics or polyphenols are secondary plant metabolites that are most commonly present in plants of high medicinal value. saikat.pharm@rediffmail.com
Total flavonoid content: Flavonoids and phenolic compounds in general are commonly known as plant secondary metabolites that hold an aromatic ring bearing at least one hydroxyl groups. 3.2. Moreover, U. dioica (81.4945 mg RE/g DW) and S. bachtiarica (41.5445 mg RE/g DW) have the highest flavonoid content among the investigated plants. The phenolic content was determined by using Folin-Ciocalteu assay. The plants were selected based on their availability and folklore medicinal value. The anti-oxidant activity and total phenolic content of alcoholic extracts from seven medicinal plants (Asparagus racemosus, Ocimum sanctum, Cassia fistula, Piper betel, Citrus aurantifolia, Catharanthus roseus, and Polyalthia longifolia) were evaluated by using a model system consisting of β-carotene, DPPH free radical and Folin-Ciocalteu method.
