Baobab (Adansonia digitata L.) as a remedy to human livelihood challenges: a review
5-11Views:373Baobab (Adansonia digitata L.) is a unique plant predominant in different ecosystems in Africa. This review assessed its value in relation to human nutrition, health, and related aspects. Our synthesis shows that baobab leaves, seed oil, and fruit pulp were utilised in different forms. Baobab tree products such as fruit pulp, leaves, and seed oil contain high levels of macronutrients, micronutrients, vitamins, carbohydrates, and proteins. Therefore, promoting the utilization and processing of baobab products for improved human nutrition is key. However, the determination of optimal parameters through elemental traceability as well as the relationship between geographical locations and nutrient composition of the baobab plant is required. Altogether, promoting innovative utilization of baobab products by exploring processing techniques to develop novel food and product formulation from Adansonia digitata tree products sheds a green light to sustain human livelihoods.

Desert greens: Unveiling the antioxidant power and health benefits of Qatar's locally grown leafy vegetables
11-17Views:523The long-term consumption of diets rich in plant polyphenols has a high potential to reduce the risk of chronic diseases such as cancer, cardiovascular disease, and diabetes. This study focuses on the phenolic and antioxidant properties of eight green leafy vegetables, red spinach, green spinach, water spinach, chives, rocca, Swiss chard, jute mallow, and purslane, commonly cultivated in Qatar. Antioxidant capacity (AC) was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method. The total phenolic content (TPC) of the samples was quantified using the Folin-Ciocalteu assay. Among all the vegetables, results indicated significant differences among all examined values at level of 5% Jute Mallow exhibited the highest phenolic content at 205.39±11.50 mg GA/100g, followed by Green Spinach at 189.58±10.56 mg GA/100g and Red Spinach at 185.15±2.93 mg GA/100g. Swiss chard exhibited the highest antioxidant activity of 89.26%. This study provides valuable data on these vegetables to positively affect the health and well-being of the population. Intensifying further future investigation to embrace a wider phytochemical profile (e.g., flavonoids, carotenoids, vitamin C), varied antioxidant assays (e.g., FRAP, ABTS), and bioavailability tests would expand the understanding of the studied leafy vegetables health benefits.
