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.

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.

Objective: To perform Phytochemical Screening and Evaluation of Antioxidant Activity of hydroalcoholic extract Justicia procumbans leaf. Methods: Proximate analysis in terms of ash value, extractive value was performed as per the standard method. Presence of secondary metabolites in the extract of Justicia procumbans was performed through various chemical tests. Folin-Ciocalteu assay method was used to determine total phenolic content and the in-vitro antioxidant activity was investigated in a dose-dependent manner with the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and hydrogen peroxide free radical scavenging method. Results: Present studies revealed that the hydro-alcoholic extract of leaf contains secondary metabolites such as alkaloids, steroids, flavonoids, carbohydrates, proteins, and tannins. Total phenolic content was found to be 79.32±0.02 mg/gm by using the Linear Equation. IC50 value by DPPH and H2O2 methods was found to be 68.83µg/ml and 56.02 µg/ml respectively. Conclusion: It has been observed that the plant has high phenolic compounds and antioxidant activity. Therefore his plant can be the potent source of natural antioxidants as compared to synthetic compounds.

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).
