Database Economic value, endogenous knowledge and distribution of Picralima nitida (Stapf) T. Durand & H. Durand in Africa. 2020. Ethnobotanical and Geospacial data

This dataset on Picralima nitida species was collected in two climatic zones of West Africa. It regroups the ethnobotanical data presented in sheet 1 and geospacial references presented in sheet 2 and 3. Picralima nitida (Apocynaceae) is an important African medicinal plant species. It is very used in traditional medicine and pharmaceutical industries for manufacture of drugs against infectious diseases, malaria, diabetes and cancer. Despite its important, the species becomes rare, especially in the Dahomey Gap in contrast to the Guineo-Congolese region. There is also a controversy on its distribution. To ensure the sustainable use of this species, this study evaluated the economic value, endogenous knowledge and the effect of climate gradient on the distribution of the species in Africa.本数据集聚焦Picralima nitida物种，采集自西非的两个气候带。其整合了表1所载的民族植物学数据，以及表2与表3中的地理空间参考信息。Picralima nitida（夹竹桃科，Apocynaceae）是一类重要的非洲药用植物，在传统医药与制药工业中应用广泛，用于制备对抗传染病、疟疾、糖尿病及癌症的药物。尽管该物种具有极高价值，但如今已趋于稀有；与几内亚-刚果区域相比，达荷美缺口（Dahomey Gap）的该物种濒危状况尤为显著。此外，学界对其分布范围尚存争议。为保障该物种的可持续利用，本研究评估了其经济价值、本土传统知识，以及气候梯度对非洲境内该物种分布的影响。
