A number of tropical fruits are cultivated in almost all parts of northern Nigeria with high nutritional value that plays important role in human nutrition. This study was aimed at evaluating the proximate and mineral element composition of the five tropical fruits (Shea Guava, Water melon and Orange) that are widely consumed in Kano state Nigeria. The proximate composition of the studied fruits were determined by the standard methods Chemists, while the Mineral Elements (Ca and Mg) were analyzed using Atomic Absorption Spectrophotometry. The levels of Na level of P was determined by Vanadomolybdate method. T that water melon has the highest moisture and protein contents (95.3±0.7% and 7.7±0.8% respectively). Shea fruit recorded the highest ash, lipid and energy value (7.35±0.5%, 2.12±0.8% and 1516.7±8KJ/100g respectively). Orange has the highest available carbohydrate (86.54±1.7%) while mango has the highest fiber content (13.52±0.2%) among the studied fruits. Similarly, Concentration of Ca was found to be highest in the pulp of orange (0.277±0.025mg/100g). The levels Mg were found to be highest in the peel of water melon (30.0±0mg/100g). More so, the levels of K and P were highest in the peel and pulp of guava (138.9±4.8mg/100g and 48.6±0.2mg/100g respectively) with significant difference (p<0.05) between the studied segments of the fruit. The level of Na was found to be highest in the peel of mango (6.7±0.7mg/100g). The results obtained show that the studied samples of fruits are rich in total protein, available carbohydrate and crude fiber. Likewise, the fruits also ha of K, Mg, Na and P but poor sources of Ca. Hence, consumption of such fruits could improve the nutritional status of the consumers.

“…For many centuries, the indigenous communities have managed the forests in a sustainable manner by keeping the rotation of their shifting cultivation long enough (15-20 years) [17,18]. Population pressure, overcropping, soil erosion, indiscriminate illegal logging in forest areas, lack of suitable land, shifting cultivation with shortened fallow period (3-4 years) [7,15,[17][18][19][20] result in falling yields and 2 Advances in Ecology drastic loss of forest coverage leading to land degradation [21]. Several studies were carried out in the recent years to investigate the plant diversity and community structure status in Sitapahar reserve forest of Chittagong Hill Tracts (South) Forest Division, Chunati Wildlife Sanctuary, Ukhiya natural forests of Cox's-Bazar Forest Division, and Bamu reserve forests of Cox's Bazar.…”

Biodiversity erosion particularly in developing countries is a matter of great concern to the global ecological community. Species composition and regeneration indicate the health of forest. This study explored tree species composition and regeneration of natural hill forest of Shitalpur under Chittagong North Forest Division through 27 sample plots of 20 m × 20 m for trees and 2 m × 2 m for regeneration. A total of 47 tree species belonging to 29 families and 17 regenerating species belonging to 15 families were recorded. The tree stem density, basal area, and wood volume were 0.49 m 2 /ha, 1425 stem/ha, and 189.9 m 3 /ha, respectively. Mean regeneration was significantly higher in bottom hill (14374 seedlings/ha) compared to top hill (9671 seedlings/ha). Toona ciliata was highest (4444 seedlings/ha) at the bottom hill compared to other hill positions. The result shows that only 36% of the tree species (17 out of 47) are regenerating in the study area, meaning majority of the tree species (64%) are not getting favorable conditions to regenerate. This might be due to absence of mature tree species as a result of overexploitation by local people. The findings may help in monitoring the species composition changes over time and adopting specific conservation programs for Shitalpur Forest.

“…A large number of tropical fruits and vegetables were grown in Bangladesh have a high nutritional value and play an important role in human nutrition (Rahman et al, 2007) and also enriched in antioxidant, minerals, vitamins and dietary diversification (Jahan et al, 2011). Small amount of micronutrients are needed for good health along with energy.…”

Physico-chemical properties and mineral contents of tropical fruits available at local market in Dhaka city were evaluated as fruits are the essential part of human diet to supply required micronutrient. Among the analyzed fruits, maximum and minimum amount of moisture was found in java apple (93.26±1.77%) and indian plum (66.86±1.81%) respectively. Mango contains highest amount of total soluble solids (15.20±0.81%) and total sugar (4.71±0.08%). Highest and lowest amount of vitamin C was found in guava (212.82±6.92 mg/100g) and java apple (10±1.77 mg/100g) respectively. Approximate energy value was found highest in indian plum (128.1±5.51kcal/100g) and lowest in green palmyra palm (27.7±2.64 kcal/100g). Indian plum (139.32±9.53mg/100g) and mango (34.03±6.81mg/100g) contain highest and lowest amount of sodium whereas rose apple (75.15±0.02mg/100g) and mango (10.23±1.94mg/100g) contain highest and lowest amount of potassium respectively. Heavy metals (As, Cd, Pb and Hg) were not detected in analyzed tropical fruits. This study suggests that the tropical fruits are enriched in micronutrients.
