... The processes of semen cryopreservation and thawing affect sperm membrane integrity and motility and increases morphological defects as well as DNA damage. The most influential cause of this is oxidative stress. When endogenous antioxidant capacity of seminal plasma is reduced during the freeze-thawing process, plant extracts exhibiting strong antioxidant activity can be used as supplements for co ...
... BACKGROUND: The dormancy of Adansonia digitata seeds is well known. For propagation purposes, plenty of germination tests were conducted, however, rarely taking the ecology of baobab into account. Our main goal, therefore, is to identify the decisive natural trigger for breaking the dormancy. We therefore performed 31 different tests and their influence on the germination rate (time to germination ...
... Food-to-food fortification of staple cereal products using nutrient-dense plants shows promise to address multiple micronutrient deficiencies including vitamin A, iron and zinc in Sub-Saharan Africa. However, there is limited information on the potential interaction effects that such food-to-food fortified strategies may have on individual micronutrient bioavailability. The main objective of the c ...
... The present study was conducted to evaluate the oxidative stability and the physicochemical, microbiological, and sensory properties of beef patties formulated with different concentrations (1%, 2%, and 3%) of baobab seed extract (BSE) during storage at 4 °C. The BSE contained a considerable number of phenolic compounds and exhibited antioxidant and antimicrobial activities (both on gram-positive ...

Abstract:
... Polysaccharides have been isolated at pH 6.0 or 2.0 from fruits and leaves of two varieties of baobab (Adansonia digitata L.). The isolation protocol was designed to study the influence of pH on the structural and functional characteristics of polysaccharides. The polysaccharides were examined by means of sugar composition analysis, NMR spectroscopy, size exclusion chromatography (SEC) and dilute ...
... A better understanding of environmental factors driving natural pest regulation is a major challenge for designing sustainable cropping systems. The objective of the present study was to assess the association between vegetation openness in traditional tree-crop agroforestry systems in Senegal, richness and abundance of vertebrates including insectivorous birds and bats, and their contribution to ...

Abstract:
... The iconic African baobab tree (Adansonia digitata) has “chiropterophilous” flowers that are adapted for pollination by fruit bats. Although bat pollination of baobabs has been documented in east and west Africa, it has not been confirmed in southern Africa where it has been suggested that hawk moths (Nephele comma) may also be involved in baobab pollination. We used a ci ...
... Sub-Saharan Africa (SSA) is among the poorest region in the world, and undernourishment continues to be a great challenge although this region is endowed with a lot of underutilized plant species (UUPS), which are rich in nutrients, especially micronutrients that are unavailable in staple foods. The potential for fortifying major staple foods with UUPS could be the remedy. This study seeks to prov ...

Abstract:
... Baobab is a deciduous non-timber tree species that are facing severe threats from both anthropogenic and climatic pressures across its range states. This study assessed natural rates of recruitment and associated threats of baobabs within and across different land-use types in semi-arid areas of Tanzania. The study was based on a stratified random sampling design composed of the following land-use ...
... Blends of cereals and nutrient dense plant materials are increasingly being explored as a strategy for food-to-food fortification in areas of Sub-Saharan Africa, where processing is often applied to enhance product attributes, shelf life and safety. However, little is known regarding the potential impact of these strategies on micronutrient retention and bioaccessibility. In this study whole grain ...
... The marketability of blueberries over long distances has been limited because of their highly perishability. To prolong the postharvest shelf life and conserve quality properties of blueberry, various alternatives have been evaluated. We studied the influence of gum arabic (GA) alone or GA enhanced with African baobab (AB) fruit extract on blueberry during cold storage (4 °C) for 21 days. Physico- ...
... This work aims to determine the applicability of Natural Esters (NE) like Baobab Oil (BAO) and Mongongo Oil (MGO) in power transformers. The dielectric property of Kerosene (KER) is utilized to decrease the viscosity of natural esters to promote better oil circulation in transformer tanks. Kerosene, being non-volatile and a good lubricant, protects alkali metals from oxidation/corrosion and its mi ...
... Adam M, Ahmed AA, Yagi A, Yagi S. 2020. Ethnobotanical investigation on medicinal plants used against human ailments in Erkowit and Sinkat areas, Eastern Sudan. Biodiversitas 21: 3255-3262. The present study provides ethnobotanical data for the traditionally used medicinal plants of Erkowit and Sinkat, Eastern Sudan. The survey data were collected from 53 traditional healers through a survey carri ...
... In a less-favored area such as the Sahel, promoting sustainable management, breeding, and conservation of forestry resources would result in improvements for agroforestry systems and food security. A contingent ranking exercise allowed us to estimate the preferences and the values given by the rural population to the attributes that would be comprised in a conservation program. The resulting prefe ...
... The laser pretreatment of seed is drawing pronounced attention from the scientific community for its positive impact in boosting germination, seedling , and growth of plants. In this study, the laser pretreatment of Adansonia digitata (A. digitata) seeds was evaluated. Eight laser treatments were conducted at different powers, 10, 20, 40, and 80 mW, with the two-time interval for each power at 2 a ...
... The African baobab (Adansonia digitata L.), also referred to as the "Tree of Life", is a long-lived, majestic, and multipurpose tree of sub-Saharan Africa. Internationally, a growing demand for baobab products in the food, pharmaceutical and cosmetics industries has been observed. Given this, there is a need for scientific information on the genetics and breeding of A. digitata, including cytogene ...
... Baobab (Adansonia digitata L.) is a multipurpose tree indigenous to the semi-arid and sub-humid zones of sub-Saharan Africa. Despite it’s multiple uses and valuable properties, information on its nutritional and phenotypic characteristics is rare, particularly in Eastern Africa. For the present study 64 baobab trees were sampled at six different locations of inland and coastal Kenya and the nutrit ...

Abstract:
... The impact of unsustainable land‐use conversions, changes in climate and anthropogenic activities on abundance and distribution of baobab populations was assessed in semi‐arid regions of Tanzania. Baobabs were sampled in plots of 1 km long and a 50 m wide, which were carried out in 337 grids located in different land‐use types. Transects for each land‐use type were located using a stratified rando ...
... The baobab tree (Adansonia digitata L.) is an important source of non-timber forest products in sub-Saharan Africa. Its fruits contain high amounts of vitamin C, calcium, and dietary fibre. In addition, other parts of the tree are traditionally used for human consumption, particularly during lean seasons. In line with the increasing demand for natural, healthy, and nutritious food products, the ba ...
... The importance of forests to safeguard agricultural production through regulating ecosystem services such as clean water, soil protection, and climate regulation is well documented, yet the contributions of forests and trees to provide food for the nutritional needs of the increasing human population has not been fully realized. Plants, fungi, and animals harvested from forests have long provided ...
