Phytochemicals, Antioxidant Activity and Ethnobotanical Uses of Balanites aegyptiaca (L.) Del. Fruits from the Arid Zone of Mauritania, Northwest Africa

Phytochemicals and antioxidant activity of fruits of 30 B. aegyptiaca trees naturally growing in the hyper-arid and arid zones in Mauritania were evaluated by following standard procedures. Ethnobotanical uses of fruit pulps and kernel were assessed using a structured questionnaire. Balanites aegyptiaca fruit pulp is a good source of sugars (33 g/100 g dry matter (DM)), polyphenols (264 mg GAE/100 g DM) and flavonoids (34.2 mg/100 g DM) with an average antioxidant activity of 519 µmol TEAC/100 g DM. The fruit kernel is rich in lipids (46.2 g/100 g DM) and proteins (29.5 g/100 g DM). Fruits from the hyper-arid zone exhibited high level of polyphenols, antioxidant activity and soluble tannins. Almost all of the informants (97.14%) reported the use of fruit pulp in folk medicine to treat diabetes, while 72.86% reported using the fruit pulp to treat hypertension. Kernel oil is mainly employed as ointments in the treatment of paronychia (57.14%) and dermal infections (35.71%). The predominant methods for preparing/administering fruit pulp/Kernel were maceration (58.8%), sucking fruit pulp (25.7%) and decoction (24.2%). Balanites aegyptiaca fruit contain both nutritional and health-promoting phytochemicals that could be of interest in the development of strategies for sustainable use of this neglected indigenous fruit tree.

Morphological Variations inTamarindus indicaLINN. Fruits and Seed Traits in the Different Agroecological Zones of Uganda

An investigation was carried out on variations in the morphological traits ofTamarindus indicaLINN. fruits (length, breadth, mass, and pulp mass) and seeds (number and mass) from the different agroecological zones and land use types of Uganda. Fruits were collected from the two land use types in the three agroecological zones and measured for various morphological traits. The study sites were located between 593 and 1,096 meters above sea level. ANOVA was used to test the differences in morphological traits of fruits and seeds between agroecological zones and land use types. The morphological traits relationship was determined using Pearson Correlation Coefficient (R). There were significant (P≤0.05) variations among theT. indicafruits and seed morphological traits within the agroecological zones and land use types. Lake Victoria Crescent agroecological zone recorded higher fruits morphological traits values. Wild and on-farm land use types were superior in fruits and seed traits, respectively. Many seeds per fruit (17) were recorded in Uganda (Eastern agroecological zone) than those recorded elsewhere. Significant uphill positive linear correlations between all morphological traits (P≤0.05) were observed, with the strongest relationships being between seed mass and seed number (R=0.79), fruit mass and fruit length (R=0.75), pulp mass and fruit mass (R=0.73), and seed mass and fruit mass (R=0.73). However, fruit breadth presented slightly weaker positive linear correlations with all other morphological traits. This is the first quantitative evaluation ofT. indicamorphological traits variation in Uganda. Dispersion/variation and correlation relationships suggest that all the studied morphological traits can be used for selection of plus trees for tree breeding improvement such as yield per tree. The observed variations are probably attributed to influence of agroecological zones’ factors, environmental factors, climate, land use types, and farming systems, a reflection ofT. indicaadaptation to different conditions showing high genetic and phenotypic differences to be exploited.
