Abstract: – The effect of extracts of neem (Azadirachta indica) and sunflower (Tithonia diversifolia) extracted differently with 30% ethanol+70% water and 30% methanol+70% water on mineral, vitamin and lycopene content of tomato fruit was studied. The study was carried out at the screenhouse of faculty of Agriculture, Obafemi Awolowo University, Ile-Ife in south west Nigeria. The study consisted of five treatments which are tomato plant alone (control), neem leaves extracted with (30% ethanol+70% water) + tomato plant, neem leaves extracted with (30% methanol + 70% water) + tomato plant, sunflower extracted with (30% ethanol + 70% water) + tomato plant and sunflower leaves extracted with (30% methanol + 70% water) + tomato. Each of the treatments was in triplicate and arranged in randomized complete block design. Harvesting was done between 9 and 14 weeks after planting. The fruits from each treatment were analyzed in the laboratory using appropriate methods to get the value for vitamin A, B1, B2, calcium, sodium, zinc and lycopene. The result shows that vitamin B1, calcium and sodium was significantly higher in treatment with Sunflower (30% methanol + 70% water) + tomato plant which had a mean value of 0.48 mg/100g, 10.26 mg/100g and 0.018 % for vitamin B1, calcium and sodium respectively. Control treatment had the highest value for vitamin A mean value of 2953.86 µg/100g which was significantly higher than treatments with extracts of sunflower leaves (30% ethanol + 70% water) + tomato plant and sunflower (30% methanol + 70% water) + tomato plant with mean value of 2819.22 µg/100g and 2833.74 µg/100g respectively. Treatment with sunflower leaves extract (30% methanol + 70% water) + tomato plant which had a significantly high value for vitamin B1, calcium and sodium also had a significantly high value for zinc with mean of 3.84 mg/kg while lycopene had value that was not significantly different from one another across the treatments. Vitamin B2 was significantly higher in the control treatment with mean value of 0.21mg/100g.
