ABSTRACT

The aim of this study was to evaluate some chemical properties of Muskmelon and Watermelon fruits, peels and seeds for their contents of some minerals, carbohydrates, proteins and amino acids from four locations around Al-Marj town (Al-Gabal Al-Akhder) namely Farzogha, Botraba, Sidi Arhoma and Al-Ewilia locations in Al-Marj plain. The results revealed that the fruits, peels and seeds from different locations contain Na, K, Fe, and Cu percent higher than Ca, Ni and P contents. For the carbohydrate and protein contents, the obtained results revealed that there is no high difference between the highest values (12.22 ppm) for fruits from Al-Ewilia location (F4) and the lowest value (2.44 ppm) for seeds of Al-Ewilia location (S4) for all parts of the samples. For the protein content, all parts of fruits of muskmelon and watermelon exhibited higher values of protein
contents than peels and seeds contents. Ten amino acid which they were had been detected in all parts of watermelon and muskmelon samples included: glycine, serine, isoleucine, Lucien, methionine, glutamine, asparagine, phenylalanine, tyrosine, and cysteine.
