Nutrients edit

Most parts of T. dioica are used in local traditional medicine. The fruit constituents are minerals (Magnesium, Sodium, Potassium, Copper, and Sulphur), vitamins, tannins, saponins, alkaloids, glycosides, flavonoids, steroids, pentacyclic triterpenes, and other bioactive compounds have proven that the pointed gourd promising.[5][6]

Pointed gourd is a good source of vitamins and minerals. It is a good source of carbohydrates, vitamin A, and vitamin C. It also contains major nutrients and trace elements (magnesium, potassium, copper, sulfur, and chlorine) which are needed in small quantities, for playing essential roles in human physiology. 9.0 mg Mg, 2.6 mg Na, 83.0 mg K, 1.1 mg Cu and 17 mg S per 100 g edible part.[4]
