豆科是一个重要的经济科，含有大量药用植物，其中许多广泛用于非洲传统医学。安哥拉拥有丰富的社会文化多样性，是世界上植物区系最丰富的地区之一，拥有 900 多种本土豆科物种。这项研究首次评估了安哥拉豆类的药用用途，并为促进这些独特资源的保护和可持续利用提供了新数据。我们通过回顾最重要的植物标本馆藏品和文献，并辅以最近的实地调查，记录了安哥拉的民族植物学知识。我们的结果显示，127 种本地豆科植物具有药用用途，其中 65% 对当地居民有其他重要用途。药用最多的物种是刺桐、紫荆和安哥拉紫檀。安哥拉发现的丰富植物群表明，发现具有治疗价值的新药具有巨大潜力。然而，为了饲料、食品、木材和医疗用途等多种用途而过度开发和不加区别地采集豆科植物，增加了对原生植被的威胁。迫切需要评估这些物种的保护状况，未来的行动应促进安哥拉药用植物的可持续利用以及保护战略的实施。
Leguminosae is an economically important family that contains a large number of medicinal plants, many of which are widely used in African traditional medicine. Angola holds a great socio-cultural diversity and is one of the richest floristic regions of the world, with over 900 native Leguminosae species. This study is the first to assess the medicinal uses of the legumes in Angola and provides new data to promote the conservation and the sustainable use of these unique resources. We document the ethnobotanical knowledge on Angola by reviewing the most important herbarium collections and literature, complemented by recent field surveys. Our results revealed that 127 native legume species have medicinal uses and 65% of them have other important uses by local populations. The species with most medicinal applications are Erythrina abyssinica, Bauhinia thonningii and Pterocarpus angolensis. The rich flora found in Angola suggests an enormous potential for discovery of new drugs with therapeutic value. However, the overexploitation and the indiscriminate collection of legumes for multiple uses such as forage, food, timber and medical uses, increases the threats upon the native vegetation. Efforts to assess the conservation status of these species are urgently needed, and future actions should promote the sustainable use of medicinal plants in Angola together with the implementation of conservation strategies.
