本研究对尼日利亚常见的13个科的23种药用植物进行了植物化学筛选和民族医学调查。采用半结构化访谈和与选定的信息提供者的讨论来收集有关植物的民族植物学信息。它们都含有生物碱、单宁和皂苷。甾体仅存在于12种植物中，只有5种含有酞菁素；其中20种植物中含有萜烯，19种植物中含有类黄酮，16种植物中含有心糖苷。在23种植物样本中，仅有几内亚利亚和chamae两种植物含有全部8种植物化学物质。将样品中存在的植物化学物质与其民族医学意义并列，并由此推断出植物药理作用的次生代谢物的几种建议。最后，可以说本研究所选植物的民族医学意义与其所含次生代谢物的药理作用相对应。
This study involves the phytochemical screening and ethnomedicinal survey of twenty-three medicinal plants belonging to thirteen families commonly found in Nigeria. Semi-structured interviews and discussions with selected informants were adapted to collect ethnobotanical information on the plants. It was discovered that all of them possess alkaloids, tannins and saponin. Steroid is present in only twelve of the plant species, only five have phlobatannin; terpene is present in twenty of the plants, flavonoid is present in nineteen of the plants, while cardiac glycoside is present in sixteen of the species. Leea guineensis and Uvaria chamae were the only plants among the 23 plant samples that contain all the eight phytochemicals tested. The phytochemical present in the samples were juxtaposed with their ethnomedicinal significance, and from this, several suggestions were deduced on the secondary metabolites responsible for the pharmacological actions of the plants. Conclusively, it could be said that the ethnomedicinal significance of the selected plants for this study corresponds to the pharmacological actions of the secondary metabolites they contain.
Key words: Phytochemical, ethnomedicinal, medicinal plants, bioprospecting.
