Fruits of C. adamantium (Myrtaceae) collected in different stages of maturation at Assis State Forest, São Paulo, were evaluated for nutritional composition, volatile oil profile and presence of inorganic elements. The fruit showed a high level of moisture (75.9%), low pH (4.3) and high acidity (1.2 g in citric acid). It is a significant source of vitamin C (234 mg 100 g-1). In the volatile oil, 40 compounds were identified corresponding to 93.3% of the oil contents. The major components were alpha-pinene (10.6%), limonene (10.1%) and the beta-(z)-ocimene (9.2%). Among the inorganic elements the nutrients exceed: K (1304 mg kg-1), Ca, P, and Mg from 165 to 175 mg kg-1 concentration and the microelements Fe (11.3 mg kg-1) and Al (15.9 mg kg-1). The caloric value (66.3 kcal 100 g-1) was due almost exclusively to the total carbohydrates (11.6%).
