摘要

叶菜在人体营养中很重要;然而,从尼日利亚西南部的菜肴中可以看出,它们的多样性似乎正在减少。许多受欢迎的美食在市场上已经买不到了。因此,本研究旨在鉴定和记录尼日利亚西南部的叶菜,通过向农民/销售者发放问卷评估其民族植物学用途,确保其遗传资源基础,并改善其价值链。蔬菜样本采集于尼日利亚西南部5个州的不同当地社区,使用手工/植物区系进行鉴定,并在拉各斯大学植物标本室进行鉴定。1000名受访者(每个州200人)参与了这项研究。其中女性占76.7%,男性占23.3%。共收集了26种叶类蔬菜。21种为研究区特有物种,5种为非本地物种。对农场和市场的叶菜进行民族植物学调查发现,蒲公英、大茄、黑茄、埃塞俄比亚茄、白茄、白茄等蔬菜具有较高的药用价值。它们可以单独使用,也可以与其他叶状植物一起用于治疗各种疾病,包括疟疾、伤寒、血压、胃病、心脏病和胃肠道感染。这些蔬菜物种一直被人类忽视和利用不足。一般来说,消费程度、消费范围和现金收入能力都较低,但一般种植的蔬菜除外。从叶菜中提取的DNA得到了高质量的DNA;这已经被存放在拉各斯大学的DNA银行中。这项研究记录了尼日利亚西南部叶菜的本土知识,并为该物种在DNA库中的迁地保护做出了贡献。关键词:叶菜,民族植物学,遗传保护,本土知识,未充分利用物种

Ethnobotanical Survey, Consumption Pattern and Genetic Conservation of Leafy Vegetables in South-West Nigeria
Leafy vegetables are important in human nutrition; however, their diversity as seen in the dishes in South western Nigeria appears to be diminishing. Many popular delicacies are no longer available in the markets. Therefore, this research was conducted to identify and document leafy vegetables in South West Nigeria, assess their ethnobotanical uses from questionnaires administered to farmers/sellers, secure their genetic resource base, and improve their value chain in South-West Nigeria. Vegetable samples were collected from different local communities in five South-West states in Nigeria, identified using manual/flora, and authenticated at the University of Lagos Herbarium. One thousand respondents, 200 in each state, participated in the study. Of these, 76.7% were female, while 23.3% were male. A total of twenty-six (26) leafy vegetables were collected. Twenty-one (21) species are indigenous to the study area, while five (5) species are non-indigenous. Ethnobotanical survey on leafy vegetables from farms and markets revealed that Launaea taraxacifolia, Solanum macrocarpon, Solanum nigrum, Solanum aethiopicum, Solanecio biafrae, Crassocephalum crepidioides and Basella alba are of high medicinal value. They can be used solely or as a recipe with other leafy plants in the treatment of various ailments including malaria, typhoid, blood pressure, stomach disorder, heart diseases and gastrointestinal tract infections. These vegetable species have been neglected and underutilized by humans. Generally, a low degree of consumption, extent of consumption, and cash income capacity was recorded, with exception to the commonly cultivated vegetables. Extracted DNA from the leafy vegetables yielded good-quality DNA; this has been deposited in the DNA bank at the University of Lagos. This study has documented indigenous knowledge on leafy vegetables in southwest Nigeria and contributed towards ex-situ conservation of the species in the DNA bank. Keywords: Leafy Vegetables, Ethnobotany, Genetic Conservation, Indigenous knowledge, Underutilized species
