Objective: This study was to investigate the phytochemical screening, total phenolic content (TPC), and antioxidant activity of fractions of water, ethyl acetate, and n-hexane from Dendrophthoe pentandra (L.) Miq. and mistletoe of Moringa oleifera Lam.Methods: Simplicia extracted with 96% ethanol using maceration method. Liquid-liquid extraction was used for fractionation with water, ethyl acetate, and n-hexane as solvent. Phytochemical screening, determination of TPC, and antioxidant activity were performed against these fractions. Antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl method. The TPC was measured by Folin–Ciocalteu reagent and use gallic acid (GA) as a standard.Results: Water fraction contains saponin and polyphenols. Ethyl acetate fraction contains alkaloids, flavonoids, saponins, terpenoids, and polyphenols. N-hexane fraction only contains alkaloids and terpenoids. The TPC and antioxidant activity of fractions of water, ethyl acetate, and n-hexane were 9.42±1.16%, 21.35±1.86%, and 67.40±0.82% mg GA equivalent/g fraction and 29.46 μg/ml±0.99%, 7.08 μg/ml±0.39%, and 10.90 μg/ml±1.05%, respectively.Conclusion: Fraction of ethyl acetate exhibited the highest antioxidant activity and TPC. This study showed that there were significant correlations between TPC and antioxidant activity at significance level p<0.05.

Prunus domestica L. is a member of the Rosaceae family that shows many biological activities including antioxidant, antimicrobial, antihaemolytic, anti-inflammatory, hepatoprotective activity and many other activities. In the current study, we evaluated nutritive value, phytochemical screening, total phenolic content and antioxidant activity by DPPH and FRAP method for the different extracts obtained by successive soxhlet extraction using the different solvents based on their polarity. Results show that it is a good source of energy. Phytochemical screening revealed the presence of many secondary metabolites which include alkaloids, carbohydrates, glycosides, protein, steroids and terpenoids, fixed oils and fat as well as phenolic compounds. The highest total phenolic content was found in the ethyl acetate fraction. Highest antioxidant activity by DPPH method is reported in ethyl acetate fraction (IC50 =1837.399±0.377µg/ml) while the ferric reducing antioxidant power was maximum for diethyl ether (56.032±0.985µM/ml FRAP value = 0.325±0.002).

The aim of this study is to investigate antioxidant activity and total phenolic content of ethyl acetate fraction of Sembung leaves. Sembung (Blumea balsamifera L.) is a plant that has the potential as an antioxidant because it contains secondary metabolites of alkaloids, steroids, flavonoids, saponins, and phenolic compounds. In this study, antioxidant activity was tested by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) for free radical scavenging activity assay. Evaluation of total phenolic content was tested by using the Folin-Ciocalteau method. The results showed that the ethyl acetate fraction of Sembung leaves possess showed medium antioxidant activity with IC50 valueof 221.821 compare with reference standard ascorbic acid with IC50 value 68.25 ppm. The ethyl acetate fraction of Sembung leaves has a total phenolic content of 161.101 mg GAE/g. This study provided that Blumea balsamifera leaves possess antioxidant.

In this work, we reported a comparative study on the phytochemical screening and antioxidant activity of aqueous extract from different parts of Moringa oleifera plant, i.e. leaves, twigs, stem barks, and woods. The phytochemical content of each extract was screened through qualitative analysis and followed by quantitative analysis for the determination of total phenolic content and total flavonoid content. The results showed that different parts of Moringa oleifera plant would give different extracted natural products. Either leaf or twig part of Moringa oleifera contained alkaloids, flavonoids, saponins, carbohydrates, polyphenols, proteins, amino acids, and phenolics. Meanwhile, only flavonoids, carbohydrates, and phenolics were found in the aqueous extract of the wood part of Moringa oleifera. In agreement to the phytochemical assay, the aqueous extract of leaf part of Moringa oleifera gave the highest total phenolic content (684 ± 16.7 µg GAE mL-1) and the highest flavonoid content (514 ± 26.1 µg CE mL-1) than other parts. Consequently, the leaf extract exhibited the highest antioxidant activity (64.6 ± 0.69%) which is close to the antioxidant activity of ascorbic acid (71.7 ± 0.56%) as the positive control. This finding is critical for the utilization of Moringa oleifera leaf part as the most potent source of antioxidant agents in the future.

A raw extract and four extractive fractions were obtained from Cedrus brevifolia (Cyprus cedar) bark. They were all studied regarding the phenolic content and profile using spectrophotometry and HPLC-DAD-ESI-MS. The antioxidant activity was investigated using in vitro assays: DPPH and ABTS radicals scavenging and reducing power assays. The ethyl acetate fraction had the highest total phenolic and proanthocyanidin contents; a taxifolin-O-hexoside, catechin, epicatechin and procyanidin oligomers (three dimers, two trimers) were identified in this fraction. The ethyl acetate fraction was found to possess the highest DPPH and ABTS radicals scavenging effects (EC50=13.9 ± 0.3 and 2.3 ± 0.0 μg/mL, respectively) and reducing capacity (EC50=9.1 ±0.1 μg/mL). Antioxidant effects were highly correlated with total phenolic and proanthocyanidin contents (r=0.89-0.99). These results suggest that Cedrus brevifolia bark is a new source of antioxidants.
