The fruit of Anisophyllea boehmii, known as loengo in Angola, is a wild fruit typically harvested in the Miombo forest. It is widely consumed locally and appreciated for its organoleptic qualities. It also has proven nutritional interests. However, analysis of the mineral profile of the fruit pulp using inductively coupled plasma with mass spectrometry (ICP-MS) on 7 samples collected in 3 geographical areas over 3 consecutive years revealed an uncommon aluminium content of around 8¿g¿kg-1 of dry matter. Indeed, the concentrations measured in the leaves confirmed that the plant is an aluminium hyperaccumulator. No correlation was found between the aluminium content of the pulp and that in soil. This particularly high value led to the recommendation to limit consumption of the fruit to protect local populations from excessive and repeated exposure to aluminium.
