Minerals and phytochemical analysis of bitter melon fruits and its components in some indigenous and exotic cultivars
Keywords:Bitter Melon, Momordica charantia, Minerals, Phytochemicals
The present study was designed to compare the mineral contents and phytochemicals in fruits of some indigenous and exotic bitter melon cultivars. Skin, flesh, seeds and whole fruit of each cultivar were dried at room temperature and ground to fine powder which was packed separately in air-tight plastic jars for analysis. The data revealed that all the cultivars possessed appreciable amount of minerals. Indigenous cultivars possessed higher mineral contents than the exotic cultivars. Black King was found to be desirable cultivar with high amount of potassium, phosphorous, magnesium, calcium, iron and zinc with values of 258.83, 92.92, 46.74, 48.42, 3.90 and 1.78 mg/100g, respectively. Among fruit parts, flesh portion was rich in potassium, phosphorous, magnesium, sodium and calcium followed by skin and seed. The seeds possessed relatively high amount of iron (4.44 mg/100g) and zinc (2.80 mg/100g). On the whole, flesh part of Black King is predominated in mineral profile while least quantity was observed in the seeds of Noor. All the cultivars possessed same types of phytochemicals although may vary in their abundance. Phenols, flavanoids, saponins and ascorbic acid were present in abundance in skin and flesh while seeds were found rich in alkaloids and glycoalkaloid. The variations in the chemical composition in fruit and components due to changes in agro-climatic conditions suggest that there is scope for developing cultivars to be grown in wide range of agronomic, climatic and geographic conditions with no effect on its nutrient and phytochemical profile.
