The objective of this study is to analyze and compare tannins of three common Acacia species of Sudan, since vegetable tannins are important in leather industry. Acacia nilotica and Acacia seyal samples were collected from Sunt Forest in Khartoum State, while Acacia senegal samples were collected from the Debabat Forest in South Kordofan State. Bark samples from bulk collections of the three Acacia species were extracted with boiled deionized water. The amount of tannins present in these bulk samples was determined by Folin-Denis method for total phenolic materials, followed by precipitation with hide-powder. The difference between the amount of phenolic materials present before and after addition of hide-powder represents the amount of tannins present. The percentage of tannins in the leaves, bark, and mature and immature fruits of collections of individuals of Acacia species was estimated; mature and immature fruits of Acacia nilotica contain tannins (22.15% and 22.10%, resp.). The leaves of Acacia nilotica and Acacia seyal contain tannins (11.80% and 6.30%, resp.). The barks of Acacia seyal, Acacia nilotica, and Acacia senegal contain tannins (12.15%, 10.47%, and 3.49%, resp.).

Objective: To evaluate the in vitro antifungal activity of aqueous extracts of Acacia senegal (A. senegal) and Acacia tortilis (A. tortilis) against three phytopathogenic fungi (viz., Alternaria alternata [A. alternata], Helminthosporium rostratum [H. rostratum] and Fusarium solani [F. solani]). Methods: Crude aqueous extracts of A. senegal and A. tortilis at 1%, 2.5% and 5% concentrations were used for screening. Antifungal activities of the extracts were evaluated against three phytopathogenic fungal strains (A. alternata, H. rostratum and F. solani) by poisoned food technique. Scanning electron microscopy (SEM) of the treated and untreated mycelia was employed to analyze the ultrastructural changes and Fourier-transform infrared (FTIR) spectrometry analysis was performed to identify important functional groups. Results: Aqueous extract of A. tortilis at high concentrations exhibited moderate inhibitory activity against the selected fungal strains. The aqueous extract of A. senegal showed no effect on A. alternata, while exhibited very mild activity against H. rostratum and F. solani at high concentrations (2.5% and 5%). Scanning electron microphotographs of the untreated fungal cells showed no structural changes (well‒defined mycelium and conidia without any distortion), whereas the treated cells showed structural distortions, twisted and wrecked mycelia and showed the presence of vesicles on the surface. FTIR analysis showed the presence of important functional groups such as alcohols, carboxylic acids and aromatic compounds. Conclusion: Results from this study indicate that the aqueous extracts of both A. senegal and A. tortilis have the potential to be used as natural fungicidal agents in the management of diseases caused by plant pathogenic fungi.

The study was conducted at ICAR-Central Arid Zone Research Institute, Regional Research Station, Bikaner to study the effect of tree leaf litters on yield and nutrient uptake of clusterbean-oat rotation during 2010-11 and 2011-2012. Leaf litters of seven tree species viz. Mopane: Colophospermum mopane, Gum acacia: (Acacia senegal) , Umbrella tree: (Acacia tortilis) , Indian rosewood: (Dalbergia sissoo), Sour lime: (Citrus aurantifolia), Assyrian plum: (Cordia myxa) and Bengal quince: (Aegle marmeloswere) applied in microplots of 2 x 2 meter @ 2.5 t/ha. Chemical fertilizers were used as per recommendations of individual crop. The result showed that maximum grain yield of clusterbean was obtained with the application of leaf litter treatments of Citrus aurantifolia. The increase in grain yield was in the order of leaf litter treatments of Citrus aurantifolia, Dalbergia sissoo and Aegle marmelos, respectively. The residual effect of leaf litters of Citrus aurantifolia, Dalbergia sissoo and Aegle marmelos increased the grain yield of oat by 13.3-16.0 percentage in 2010-11 and 14.8-16.1 percentage in 2011-12, respectively. There was no significant effect of leaf litters of Cordia myxa and Acacia senegal on grain yield of clusterbean and oat. Litter addition had significant effect on nutrient uptake also. The mean uptake of nutrients was significantly higher in Citrus aurantifolia, Dalbergia sissoo and Aegle marmelos treatments as compared to control. The two years average data showed that the total uptake of N in clusterbean increased from 21.3 kg/ha in control to 32.2, 28.5 and 30.8 kg/ha in Citrus aurantifolia, Dalbergia sissoo and Aegle marmelos treatments, respectively. Nitrogen, phosphorus and potassium uptake was non-significant in the treatments Colophospermum mopane, Cordia myxa, Acacia tortilis and Acacia senegal

Ethnobotany is the scientific study of the relationships that exist between people and plants. Ethnobotanists aim to document, describe and explain complex relationships between cultures and plants, focusing primarily on how plants are used, managed and perceived across human societies. This includes use for food, clothing, currency, ritual, medicine, dye, construction, cosmetics. Ethnobotanical studies are often significant in revealing locally important plant species especially for the discovery of crude drugs The documentation of traditional knowledge, especially on the medicinal uses of plants. has provided many important drugs of modern day. Out of the total flowering plants reported from the world, more than 50, 000 are used for medicinal purposes ( Govaerts, 2001 ). Extensive and intensive field trips were conducted to the study area during a course of two years from 2013 to 2015 representing several sites through Jebel Aulia district, Khartoum state. The study revealed a total of 117 species belonging to 100 genera and 45 families were recorded at Jebel Aulia locality. The family Poaceae was found to be the richest (13 species) followed by Ceasalpiniaceae, Euphorbiaceae, Mimosaceae (7 species) and Asteraceae (6 species). Herbs have dominated the vegetation of the study area (62. 40%) followed with trees (15. 40%), shrubs (8. 5%). Genus Euphorbia was considered as the most speciose (4 species) pursued with Senna and Ipomea which were represented by 3 species each. Tribulus longipetalus and Cyperus alopecuroides along with their Ethnomedicinal uses were documented for the first time. Fruits were the most commonly used plant part to prepare medicine followed with leaves and seeds. The main preparation methods of herbal remedies were infusion (25%) followed with decoction (14. 3%), edible (10. 7%) and pills (10. 7%). Oral administration was the most common route of herbal remedies within traditional medicine. Urinary tracts, kidney and abdominal complaints were the most frequent ailments traditionally healed. The source of medicinal plants was wild, (41. 66%), were cultivated (33. 34%) and (25%) were commercially bought from the market. Senna alexandrina was the most cited and important plant in the study area followed with Ziziphus spina-christi, Acacia nilotica, Solenostemma argel and Cymbopogon proximus. High informants consensus factor was indicated for Medicinal, furniture and food uses. Ziziphus spina Christi, Acacia senegal, Allium sativum and Cinnamomum verum have highest use-value ranging from (0. 062 to 0. 05). Cytotoxicity was evaluated using plants with a high relative frequency of citation. The results revealed that LC50 of water and ethanolic extracts of Acacia nilotica were more than 1000 µg/ml which considered not toxic and consequently safe at this dose. Whereas, water and ethanolic extracts of Senna alexandrina were less than LC 50 =256. 206 - 409. 6079 µg/ml. which is considered moderately toxic. Therefore, Senna extracts should be carefully used.
