“…In the case of macerates, TP contents are significantly higher (P < 0.05) in ME (119.82 mg EAG/g DM on average) than in MA (107.90 mg EAG/g DM on average). A similar trend was observed in work carried out on the species Helichrysum stoechas [49], indicating that estimated total phenolic contents are higher in ethanolic maceration (70%) than in aqueous maceration. Previous studies [51][52][53] have reported that ethanol combined with water provides better extraction of phytophenols.…”

“…In the case of decoctions, TP contents are significantly higher (P < 0.05) in DA (129.04 mg EAG/g DM on average) than in DE (84.99 mg EAG/g DM on average). An opposite trend was observed in previous studies [49,50].

“…They are significantly higher (P < 0.001) in DA (33.03 mg EQ/g DM on average) than in DE (13.42 mg EQ/g DM on average). An opposite trend has been reported by other authors [49,50], mentioning that total flavonoid contents are higher in ethanolic decoction (70%) than in aqueous decoction. For macerates, no significant difference was found between total flavonoid contents (P > 0.05).…”

Aims: This work aims to investigate the phytochemical composition and antioxidant potential of the leaves of Macaranga heterophylla. Methodology: For this purpose, phytochemical screening by detection tests and thin layer chromatography (TLC), determination of total phenols content, total flavonoids content and condensed tannins content, and assessment of antioxidant potential by DPPH and reducing power tests were carried out on aqueous crude extracts, ethanolic crude extracts and selective extracts of the leaves of M. heterophylla. Results: The percentage yields obtained with ethanol (70%) (28.90 and 24.70% for the ethanolic decoction and ethanolic macerate respectively) are higher than those obtained with water (24.30 and 21.10% for the aqueous decoction and aqueous macerate respectively). The phytochemical screening highlighted the presence of several phytochemical families such as phenolic compounds (coumarins, flavones, tannins), quinones, sterols and polyterpenes, saponosides, glycosides, cardiotonic glycosides and oligosaccharides. Quantitative analysis of total phenolics, total flavonoids and proanthocyanidols showed that their respective levels in the leaves of M. heterophylla varied depending on the solvent and the extraction technique. Concerning total phenolics, the aqueous decoction and ethanolic macerate gave the best total phenol contents (129.04 ± 9.53 and 119.82 ± 2.63 mg EAG/g DM respectively); for total flavonoids, the aqueous decoction gave the best content (33.03 ± 1.61 mg EQ/g DM), while for condensed tannins, the aqueous macerate gave the best content (0.87 ± 0.02 mg ECT/g DM). With regard to DPPH antioxidant activity, the results showed that the ethanolic decoction has more pronounced antioxidant activity than the aqueous decoction, while the aqueous macerate showed better antioxidant activity than the ethanolic macerate. Concerning the reducing power test, the opposite trend was observed. Conclusion: The present study demonstrated that M. heterophylla is a concentrate of secondary metabolites with antioxidant properties, which would explain its use in traditional medicinal practice.

Introduction-Objectif-Dans les dernières décennies il y a eu un intérêt croissant pour l’étude des plantes médicinales et leur utilisation traditionnelle pour le traitement de diverses maladies. L’olivier ou Olea europaea L. constitue une entité indissociable des peuples méditerranéens. Cette plante appartient à la grande famille des oleaceae. L’objectif de cette étude a été d’évaluer l’activité anti-oxydante des extraits éthanoliques de quatre variétés sauvages de la plante O.europaea des régions de l’Est algérien : Batna et Mila (hautes-plateaux), Biskra (Sahara) et Skikda (ville côtière). Matériels et méthodes - L’évaluation de l’activité anti-oxydante in vitro des extraits éthanoliques de la plante O.europaea a été réalisée par différentes méthodes, notamment le piégeage du radical libre DPPH• et le pouvoir réducteur des ions ferriques. Résultats -L’analyse quantitative des extraits éthanoliques des feuilles de la plante O.europaea a révélé que l’extrait de Mila était plus riche (420.36 mg GAE/g MS), suivi de celui de Batna (396.84 mg GAE/g MS), puis celui de Biskra (de 380.69 mg GAE/g MS) et enfin de l’extrait de Skikda (368.45 mg GAE/g MS). Les résultats de l’activité antiradicalaire des extraits éthanoliques ont montré que ceux de Batna et Mila possédaient le pouvoir le plus important. Conclusion -Les résultats obtenus confirment favorablement l’utilisation des feuilles d’O.europaea en médecine traditionnelle algérienne pour le traitement de diverses maladies.
