Bidara merupakan tanaman tradisonal yang daunnya mengandung tinggi polifenol sehingga berpotensi untuk dikembangkan menjadi produk teh herbal. Pengeringan daun bidara sangat berpengaruh terhadap kualitas rasa, warna, dan aroma teh. Penelitian ini bertujuan untuk mengkaji pengaruh – pengaruh yang dapat ditimbulkan dari metode pengeringan dan persentase teh kering terhadap karakteristik sampel seduhan teh bidara yang dibuat pada penelitian ini. Desain penelitian digunakan RAKF 2 faktor. Faktor pertama meliputi metode pengeringan yang sering digunakan dalam pengeringan teh yaitu pengeringan kabinet, sangrai, dan sinar matahari. Faktor 2 meliputi persentase penggunaan teh kering yaitu 1%, 3%, dan 5% dengan masing-masing 3 kali ulangan. Respon yang diuji meliputi warna, pH, fenol, flavonoid, aktivitas antioksidan, tanin, dan uji organoleptik yang dilakukan dengan uji hedonik. Penelitian ini menunjukkan bahwa teh daun bidara terbaik dihasilkan dari pengeringan sinar matahari dengan presentase penggunaan teh kering sebesar 5% dengan nilai fenol, flavonoid, tanin, antioksidan, dan skor hedonik paling optimal.

Background: In recent years, novel metabolites isolated from botanical sources have attracted much attention for traditional and therapeutic significance. The ethnopharmacological studies suggest that Ziziphus mauritiana is a common remedy against several kinds of ailments. Objective: The current study has evaluated the MeOH extract of Ziziphus mauritiana leaves (ZME) through physicochemical, phytochemical, and chromatographic fingerprinting analysis, which displayed an array of biometabolites of pharmacological significance including flavonoids. Methods: The extract was further examined for anticancer activities which revealed promising anticancer properties against human lung epithelial carcinoma cells (A549) and induction of apoptosis impart by ROS. The oxidative stress was evaluated in terms of production and accumulation of cytosolic extent of ROS whereas anticancer perspective was determined by MTT assay, cell morphology analysis, followed by nuclear condensation for the examination of apoptosis induction. Results: Finding suggests that the MeOH extract of ZME markedly exhibited promising anticancer activity against the A549 lung epithelial carcinoma cell. The ZME was found to be most active in the MTT assay against A549 cells while it was less toxic to normal cells. The intracellular ROS generation was remarkably induced by ZME, which correlated with the ability of the flavonoid-rich fractions in the MeOH extract to inhibit cell growth and might induce apoptosis. Conclusion: The present study provides useful insight concerning the promising anticancer potential of ZME against A549 lung carcinomas. However, the clinical correlation will be required for its authorization and in the discovery of significant and least noxious novel agents against lung carcinomas.

The present work aimed at mitigating the level of copper ions (Cu++) by adsorption in aqueous solution using activated carbon powder (AC) and biosorbent (BS) from the Indian jujube seed hulls. The AC and BS were prepared from the Indian jujube seed hulls and characterized    using standard procedures. In addition, the adsorption effects of Indian jujube seed hulls through the AC and BS were carried out using jar test experiment (batch mode) at different pH (1, 2, 3, and 4), ionic strengths (100-600 mg/L) and stirring speed (120rpm). Therefore, it was found that the adsorption time at equilibrium were 10 and 5 minutes respectively for the AC and the BS.  Furthermore, it was found that the reduction of copper ions were 99.40% and 73.08% for aqueous solutions of 100 ppm and 500 ppm respectively at the equilibrium state. It was also revealed that when the mass of the AC or the BS increases, the quantities of ions adsorbed per gram decrease. The maximum pH of adsorption for the AC was found to be pH=1, while it was found to be pH=4 for the BS. The Freundlich model indicated that the adsorption of copper ions by the Indian jujube is linear while the Temkin and Dubinin-Kagana-Radushkevich models described the adsorption as a physical reaction. It was finally observed that the adsorption of copper ions by the AC and the BS from Indian jujube seed hulls influenced by the addition of some concentration of NaCl.

Les espèces ligneuses jouent un rôle important dans la vie des populations locales. Parmi les espèces couramment utilisées au Niger figurent Balanites aegyptiaca et Ziziphus mauritiana. Ces deux espèces sont exploitées comme sources alimentaires et pour divers produits médicinaux, avec comme conséquence une réduction de leurs peuplements. La présente étude vise à analyser la structure des peuplements et les modes de régénération des deux espèces dans deux secteurs agro-écologiques contrastées de la région de Maradi au centre sud du Niger. Au total, 60 relevés ont été délimités, d’une part dans des formations naturelles dominées par ces espèces, et d’autre part dans les systèmes agrosylvopastoraux des secteurs sahélien et sahélo-soudanien. Dans chaque placette et sur chaque arbre, le diamètre à 1,30 m au rasdu sol , la hauteur totale et deux diamètres perpendiculaires de houppier ont été mesurés. L’inventaire de la régénération a été effectué dans 5 placeaux. La nature de la régénération (drageon, marcotte, semis naturel), la hauteur totale et le nombre de tiges de chaque plantule ont été notés. La densité de B. aegyptiaca ne varie significativement entre sites et entre secteurs. Par contre, la densité de Z. mauritiana varie significativement entre sites et entre secteurs. En effet, le site de Birni Lallé, situé dans le secteur sahélien strict, et le site de Kegil dans le secteur sahélo-soudanien ont les densités les plus élevées de Z. mauritiana avec respectivement 66,4 ± 52,5 et 77,5 ± 61,4 arbres/ha. L’analyse de la distribution des tiges par classe de diamètre montre que pour les deux espèces, les individus jeunes sont bien représentés. Cela suggère une bonne régénération de ces espèces. L’analyse de la densité et nature de régénération montre que les deux espèces se régénèrent essentiellement par drageonnage. En réponse au ramassage des fruits pour diverses utilisations, les espèces B. aegyptiaca et Z. mauritiana ont développé des stratégies alternatives de propagation en zone sahélienne. Cette aptitude à la propagation végétative permet aux deux espèces de s’adapter en zones arides caractérisées par la sécheresse et les hautes températures. MOTS CLÉS : DISTRIBUTION DES ESPÈCES LIGNEUSES, B. AEGYPTIACA, Z. MAURITIANA, MARADI, NIGER, SAHÉLO-SOUDANIEN [83] afrika focus — Volume 33, Nr. 1, 2020 — pp. 83-104 RABIOU HABOU, MOUSSA MASSAOUDOU, TOUGIANI ABASSE, MAHAMANE ALI, MAHAMANE LARWANOU & PATRICK VAN DAMME Wood species play an important role in the life of local communities. Among the species commonly used in Niger, are Balanites aegyptiaca and Ziziphus mauritiana. This species are exploited as food sources and as various medicinal products, with a consequent reduction in their populations. The present study aims to analyze the stand structure and the regeneration modes of the two species in two contrasting agro-ecological sectors of the Maradi region in south central Niger. A total of 60 surveys were delineated in natural formations dominated by these species and in agrosilvopastoral system in the Sahelian and Sahelo-Sudanian zones. On each tree, the diameter at 1.30 m from the ground, the total height and two perpendicular tree crown diameters were measured. The inventory of natural regeneration was carried out in 5 plots delineated in each plot. The mode of reproduction of the regeneration (suckers, marcots, natural seedlings) was recorded as well as the total height and the number of stems of each juvenile were. The density of B. aegyptiaca does not vary significantly between sites and between sectors. The Birni Lallé site, located in the strict Sahelian zone, and the Kegil site in the Sahelo-Sudanese sector stand out in terms of Z. mauritiana density with respectively 66.4 ± 52.5 and 77.5 ± 61.4 trees. /Ha. The analysis of the diameter class structure shows that for both species, young individuals are well represented. This suggests strong regeneration among these species. The analysis of the density and nature of regeneration shows that the two species regenerate mainly by suckering. In response to the collection of fruits for various uses by local populations, B. aegyptiaca and Z. mauritiana have developed alternative propagation strategies in the Sahelian zone. This ability to propagate vegetatively allows these two species to adapt to arid areas characterized by drought and high temperatures. KEY WORDS: DISTRIBUTION OF WOODY SPECIES, B. AEGYPTIACA, Z.
