Aims: To estimate the phytochemical and vitamins composition and the antioxidant activity of Pelargonium inquinans leaves. Background: Some plants that are used in the traditional setting for the management of different ailments have documented observations and scientific studies. However many other plants lack scientific reports to support their medicinal use. One of such plant is Pelargonium inquinans Ait that is traditionally used to treat headaches and flu by tribes in South Africa. Not much is known about its chemical composition. Methods: The phytochemical composition of acetone, aqueous and ethanol extract of leaves of Pelargonium inquinans as well as the vitamins A, C and E of its dried weight leaves and the antioxidant activities were evaluated using standard in vitro methods. The phytochemical composition and vitamins were determined spectrophotometrically, while the antioxidant activities were determined by DPPH, nitric oxide and hydrogen peroxide scavenging activity and phosphomolybdenum (total) antioxidant activity. Statistical analysis: The One-way analysis of variance (ANOVA) and the Tukey test were used to determine the differences among the means of the various samples. Results: The phytochemical composition differ significantly in the various extracts. The total phenolics were higher than other phytochemicals in all the extracts used. The hydrogen peroxide and DPPH scavenging activity were very high and dose-dependent. The aqueous extract had the highest antioxidant activity at 98.4 \% of control (hydrogen peroxide), while the ethanol extract had the lowest at 37.5\% control (nitric oxide). Conclusion: The results supports the notion that the Geraniaceae family and Pelargonium inquinans in particular is rich in polyphenolic compounds and has good antioxidant activity.

Introduction: Many potential compounds have antioxidant activity, such as the flavonoid group, phenolics and carotenoids. Phyllanthus emblica is widespread in Bandung-Indonesia and is a very potent as an antioxidant activity. Antioxidant activity and correlation with total flavonoids, phenolics and carotenoids from Phyllantus extract from Bandung-Indonesia have not been reported. The aim of this research were to determine the antioxidant activity from extract of various parts of P. emblica and its correlation of antioxidant activity with the total flavonoid, phenolics and carotenoid. Method: Successive extractions of various part of P.emblica were performed by maceration using differrent polarity solvent n-hexane, ethyl acetate and ethanol. The antioxidant activity of each extracts was performed using DPPH (2.2-Diphenyl-1-Picrylhydrazil) method. The determination of total flavonoids, phenolics and carotenoids were performed by UV-Spectrophotometry. Antioxidant activity was demonstrated by IC50 and its correlation to total flavonoids, phenolics and carotenoids using the Pearson\’s method. Result: The highest antioxidant activity was given by fruit ethyl acetate (BE) extract with IC50 3.032 \μg/mL. Etyl acetate extract of stem bark P.emblica (KE) had the highest of total phenol content (12.818 g GAE/100 g), ethanol extract of leaves P.emblica (DO) had the highest of total flavonoid content (3.594 g QE/100 g), and n-hexane extract of leave (DN) had the highest of total carotenoid content (0.759 g BE/100 g). Conclusion: According to coeficient correlation Pearson\’s between P. emblica extract with IC50 of DPPH scavengging activities, suggested that flavonoid and phenolic compound in stem bark extract and leaves extract of P. emblica were contributor major in its antioxidant activity with DPPH methode, and its same with carotenoid content in leaves extract of P. emblica.
