## 1 Introduction  
The African continent has a wide variety of wild plants and cultivated native species with significant agronomic, commercial, and nutritional potential. It is estimated that more than two-thirds of the continent's population of 600 million depend directly or indirectly on forest resources, either for subsistence or as a source of income [1].  
The Mismbo woodlands are the most extensive forest in southern and eastern Africa, covering about 2.7 million km\({}^{2}\), characterized by a hot and dry climate that allows for the formation of seasonal tropical forests [2, 3]. The area substantially extends into seven southern African countries: Angola, Zimbabwe, Zambia, Malawi, Mozambique, Tanzania, and the largest part in the south of the Democratic Republic of the Congo [2, 3, 4, 5]. This region is characterized by areas where the average annual rainfall is around 700 mm, that have low nutrient soils, and in which the genera _Brachytsegia_, _Julbernardia_, and _Isoberlinia_ predominate [3; 5; 6].  
This particular ecosystem includes many species of wild fruit trees and shrubs that produce edible fruits that are widely consumed by local populations and also largely harvested for sale in large city markets. Among these local resources, the fruits of _Anisophyllae boehmii_ Engl., called loengo in Angola, are particularly appreciated by both the rural and urban populations [7].  
As for the morphological characteristics of the plant, it is a tree that reaches 10 to 15 m in height. The leaves are alternate, simple, oval, or elliptical, and shiny dark green on the upper surface. The fruit is a drupe of an ellipsoidal shape and a dark purple color [8; 9; 10]. These plum-like fruits appear during the rainy season and are eaten fresh and also prepared as juices, jellies, or added to porridge [11; 12]. Some studies have shown that the pulp of the fruit contains several compounds of interest, such as beneficial minerals and bioactive antioxidants (phenolics and carotenoids), and that its kernel contains around 30% oil, rich in unsaturated fatty acids, such as oleic, palmitoleic, and linoleic acids [9; 11; 13].  
[PERSON] [12] conducted a population survey in Copperbelt, Zambia on the uses of the _A. boehmii_ Engl. plant that revealed that it is also exploited for its medicinal properties, where an infusion of the roots is used to treat dysentery and diarrhea, while bark decoctions are used to treat syphilis, stomach aches, and as a mouthwash to treat toothache and bleeding gums.  
Scientific knowledge of this fruit, which is therefore common in the eating habits of the Miombo region, nevertheless remains poor; it is barely characterized. In the Angolan context, the proposed work aims to provide elements for a better assessment of the commercial, nutritional, and organoleptic potential of the fruit. To begin with, a field survey was carried out to gain an insight into consumers' eating habits regarding this fruit. Then, in order to complete the only work carried out on the fruit pulp by [PERSON] et al., 2024 [13], who determined the proximate composition, this study presents for the first time an original detailed study of the characteristics and composition of loengo and its variability, through a comparison of different samples collected in Angola.
