Sub-Saharan Africa continues to struggle with food insecurity, which has been made worse by issues like the COVID-19 pandemic and climate change. In the African continent, plants have been used for food and medicine for many generations. Morula (Sclerocarya birrea), Moretologa (Ximenia americana), Mowana (Adansonia digitata L.), and Mogose (Bauhinia petersiana) are among the most consumed indigenous plants in Botswana. The objective of this study was to analyse nutritional and phytochemical profiles of these indigenous plants. The results showed that protein content ranged between 1.80% (Morula) and 25.54% (Mogose). The highest fat content of 14.29% was observed in Mogose seeds. Mowana proved to be rich in calcium compared to other plants. Manganese was detected only in Mogose samples. Phytochemical screening showed the presence of various phytochemicals. Moretologa proved to be a good source of beta carotene (419.33 μg/100 g). The plants contained different amounts of ascorbic acid; 163.83, 141.59, 24.78, and 3.00 mg/100 g were recorded in Mowana, morula, Moretologa, and Mogose, respectively. Total phenols ranged between 7.98 mg/100 g (Moretologa) to 14.3 mg/100 g (Mowana). The four indigenous plants proved to have good nutritional qualities and their increased consumption may contribute positively towards efforts to attain food security in Botswana. Additionally, the plants are good sources of phytochemicals, and they may aid in the discovery of novel drugs and medicines and be useful in formulation of functional foods.

The emergence and evolution of antibiotic-resistant bacterial strains has shifted interest in herbal therapy. Plants have long been a source of anti-infective compounds. This study investigated the antibacterial activity and phytochemical composition of various Palestinian plants against five human pathogenic bacteria. Antibacterial activity was determined using the Agar Diffusion Method (ADM), as well as the Minimal Inhibitory Concentration (MIC) and Broth Microdilution (BMD) assays. The successful ADM bacterial inhibition zones employing plant extracts were Eucalyptus camaldulensis Dehn. (E. camaldulensis) 9.35 mm, Allium sativum L. (A. sativum) 8.35 mm, Ceratonia siliqua L. (C. siliqua) 7.85 mm, and Amygdalus communis L. (A. communis) 7.85 mm. The MIC50 values against the tested microorganisms varied from 5.69 to 398.5 mg/mL. Furthermore, the MIC50 values for Gram-positive bacteria varied from 5.69 to 233.88 mg/mL, whereas the values for Gram-negative bacteria ranged from 28.65 to 398.5 mg/mL. Most species of bacteria were effectively inhibited by E. camaldulensis and A. sativum extracts. For Gram-positive and Gram-negative bacteria, the MIC50 values for E. camaldulensis were 39.01-40.38 and 31.60-85.37 mg/mL, respectively. The MIC50 values for A. sativum against Gram-positive and Gram-negative bacteria were 5.69-14.85 mg/mL and 38.98-200.11 mg/mL, respectively. The phytochemicals such as flavonoids, steroids, proteins, carbohydrates, and alkaloids in varying amounts, may explain their diverse capability to inhibit bacteria. The present study showed that E. camaldulensis, A. sativum, C. siliqua and A. communis are valuable Palestinian medicinal plants that contain antibacterial agents against the tested bacterial species. However, this study serves as a foundation for further pharmaceutical studies.

“…To 2 ml of the filtered extracts, 5 ml of distilled water was added to a test tube. The mixture was shaken vigorously to observe for the appearance of stable persistent froth on warming, as preliminary evidence for the presence of saponins (Abba, Inabo, Yakubu, & Olonitola, 2009).…”

Anchote (Coccinia abyssinica (Lam.) (Cogn)) is an endemic and potentially valuable crop of Ethiopia principally categorized under root and tuber crops, and its newly growing leaves along with the tendrils are also used as nutritious vegetable served after being cooked. Leaf and tuber powders were extracted for the first time to identify volatile organic compounds by simultaneous steam distillation and solvent extraction (SDE) and characterized using gas chromatography mass spectrometry (GC-MS). VOCs having an area percentage above 0.5% were used for identification analysis. From the results, thirty volatile flavor compounds from leaves and fifteen from tubers were identified with the total fraction yield of 770.57 mg/kg and 4536.91 mg/kg, respectively, and from the 30 compounds identified from leaf 16 were distinguished in each of the tested accessions. Ethyl acetate 90.47% (697.13 mg/kg) was detected in a higher amount exhibiting >1% peak area. The rest 6.03% (46.46 mg/kg) were minor quantities (<1%) of the total (770.57 mg/kg) volatile flavor fraction. Among the 15 identified compounds in the tuber, ethyl acetate was the only major compound that accounted together for 99.15% (4498.33 mg/kg) of the total volatile flavor fraction and 0.85% (38.58 mg/kg) being reported in minor quantities (<1%). The SDE extraction and GC-MS analysis of anchote leaves and tubers successfully identified various volatile flavor compounds, which indicates that anchote was found to be a potential source of volatile flavor compounds that can be used as a food flavoring agent and in folk medicines. Thus, this study confirms that anchote leaf and tuber can be used for more specific and valuable applications in food and medicine industries.
