Abstract: Sudanese use Roselle, Adansonia digitata, and Tamairndus indica as juices almost daily at home, especially, during fasting month “Ramadan”. The juices are popular even in some restaurants and hotels. Roselle is used as a hot drink after boiling. The aim of this study was to determine some essential physicochemical properties of the three fruits by studying their water extract. The study also aimed to check if there is any component which may have a health negative effect for the consumers. The measured parameters include; Moisture content, Ash content, pH value of 10% solution and Total acidity. Total acidity was determined by potentiometric titrations. Inductively Coupled Plasma emission spectrometry has been used for determination of macro, trace, and toxic minerals. The results showed significant concentrations of some nutrient elements such as Potassium, Calcium and Iron. Roselle showed very high potassium concentration. The three fruits show high aluminum content and noticeable concentrations of Lead. The highest concentration of lead was found in Adansonia.
