Abstract

An ethnobotanical survey was conducted among traditional healers and herbalists in eastern Kinshasa (Democratic Republic of the Congo) to identify medicinal plant species traditionally used to treat diabetes mellitus. Fifty traditional healers and herbalists selected through the snowball sampling method were interviewed about plant species used in indigenous medicine to treat diabetes mellitus in Kinshasa city. Cited plant taxa were collected and identified at the Herbarium of the Faculty of Science & Technology, University of Kinshasa. Their ecological status was determined. Most respondents were male (58%), with a sex ratio 1.38. According to the marital status of respondents, single persons represent 42%, followed by married (32%), divorced (20%), and widowed (06%), respectively. Out of 50 persons interviewed, the most represented age group comprises individuals of ˃50 years. Most informants have a secondary school educational background (46%). In Kinshasa city, medicinal plants for treating diabetes mellitus are divided into 19 families, 25 genera, and 27 species. The culture/crop and forest plant species represent the most (37.04% each). The ecological and phytogeographical spectra revealed a predominance of trees (33.33%), microphanerophytes (48.15%), mesophytes (85.19%), sarcochores (66.67%), and pantropical species (40.74%). 68% of the population of Tshangu district in Kinshasa city uses Traditional Medicine, against 32% who are interested in modern medicine. 63% of them believe that medicinal plants can cure diabetes, 31.5% believe that plants improve their health, and 15% of the population surveyed believe that medicinal plants have side effects. The leaves are the most used part (40.74%), followed by the roots (25.93), fruits (18.52%), grains (7.41%), flowers, and stems (3.7% each). Promoting ex-situ conservation of some of these useful medicinal plants through in vitro cell culture will permit the preservation of these phyto-resources. Keywords: Indigenous knowledge, medicinal plants, ex-situ conservation, metabolic diseases, diabetes mellitus.

刚果民主共和国金沙萨市东部传统用于治疗糖尿病的药用植物的民族植物学调查
在金沙萨东部(刚果民主共和国)的传统治疗师和草药医师中进行了民族植物学调查,以确定传统上用于治疗糖尿病的药用植物物种。通过滚雪球抽样法对金沙萨市50名传统治疗师和草药医师进行了访谈,内容涉及治疗糖尿病的土着药物中使用的植物种类。被引植物分类群在金沙萨大学科技学院植物标本室收集并鉴定。确定了它们的生态状况。大多数受访者为男性(58%),性别比为1.38。根据受访者的婚姻状况,单身占42%,其次是已婚(32%)、离婚(20%)和丧偶(06%)。在接受采访的50人中,最具代表性的年龄组包括50岁以下的个人。大多数举报人有中学教育背景(46%)。金沙萨市治疗糖尿病的药用植物分为19科25属27种。栽培/作物和森林植物种类最多,各占37.04%。生态和植物地理光谱显示,乔木(33.33%)、小显生植物(48.15%)、中生植物(85.19%)、藤本植物(66.67%)和泛热带植物(40.74%)占优势。金沙萨市Tshangu区68%的人口使用传统医学,32%的人对现代医学感兴趣。其中63%的人认为药用植物可以治疗糖尿病,31.5%的人认为植物可以改善他们的健康,15%的被调查者认为药用植物有副作用。叶子是使用最多的部分(40.74%),其次是根(25.93%)、果实(18.52%)、谷物(7.41%)、花和茎(各占3.7%)。通过体外细胞培养促进这些有用药用植物的迁地保护,将使这些植物资源得以保存。关键词:本土知识;药用植物;迁地保护;
