Physico-chemical characteristics and antioxidant assay of tomato (Lycopersicon esculentum Mill.) germplasm available in the South Western region of Bangladesh

The research work was carried out to determine the physico-chemical characteristics and antioxidant assay of 13selected tomato germplasm collected from the south-western region of Bangladesh during December 2012 toMay 2013. The experiment was laid out in a Completely Randomized Design (CRD) with three replications. Asignificant variation among the germplasm in relation to fruit characteristics was observed. The highest valuesfound in germplasm No. 6 in respect of total weight of fruit, length of fruit, width of fruit and depth of fruitamong the 13 selected germplasm. The highest seed weight of fruits was observed in germplasm No. 2. Thehighest titrable acidity (0.953%) was observed in germplasm No. 12. The highest vitamin C (24.33 mg /100 g)content of fruit pulp was determined from germplasm No. 3 while germplasm No. 13 was best in respect of pH(4.833), germplasm No. 3 in total soluble solids (6.033%) content, germplasm No. 5 in carotenoids (0.848 mg/100 g) content, germplasm No. 2 in anthocyanin (0.125 mg/100 g) content and germplasm No. 11 in flavonoids(5.270 g/100 g) content of fruit pulp. The highest antioxidant was found in germplasm No.7 and that was lowestin germplasm No. 9. The IC50 values and antioxidant content is opposite each other. It was revealed from thestudy that germplasm No.7 had comparatively lover IC50 values so, germplasm No.7 contain comparativelyhigher antioxidant content. On the other hand, germplasm No. 9 had comparatively higher IC50 values so,germplasm No.9 contain comparatively lower antioxidant content
