Abstract

The first ethnobotanical work of the genus Smilax in Thailand was carried out to investigate the medicinal use of the Smilax species by folk healers, using the semi-structured interview, questionnaire survey, and literature review. Three quantitative indices were calculated, i.e. the Use Value (UV), the Relative Frequency Citation (RFC), and the Informant Agreement Ratio (IAR). Eleven species were recorded. Three of which, i.e. S. bracteata, S. hemsleyana, and S. leucophylla, are new records as medicinal species in Thailand. The genus has the potential use for the treatment of the genitourinary illnesses (IAR=1.00) and the neoplasms (IAR=0.71). Smilax glabra was the most used species with UVs=0.67, RFC=0.39. The results indicate the species being threatened due to over harvesting from the natural habitat. Furthermore, this study shows that the semi-structured interview coupled with the questionnaire survey is useful to gather the ethnobotanical data of a specific plant group. Botanical authentication of the commercial crude drugs based on chromatographic fingerprinting and macroscopic characters was carried out to verify the botanical identity of the homonym Hua-khao-yen crude drugs. Smilax glabra and Premna herbacea (Lamiaceae) were authenticated as the source of Hua-khao-yen-nuea and the Hua-khao-yen tai crude drugs, respectively.

泰国菝葜属植物的民族植物学研究及其花khakyen药材的植物学鉴定

本文采用半结构化访谈法、问卷调查法和文献综述法，对泰国菝葜属植物进行了首次民族植物学研究。计算了文献的使用价值(UV)、相对被引频次(RFC)和信息者同意率(IAR)三个定量指标。记录了11种。其中3种为泰国新记录的药用种，分别为苞片蒿(S. bracteata)、hemsleyana和白叶蒿(S. leucophylla)。该属对泌尿生殖系统疾病(IAR=1.00)和肿瘤(IAR=0.71)有潜在的治疗价值。利用最多的种是光菝葜，其uv =0.67, RFC=0.39。结果表明，由于从自然栖息地过度采伐，该物种受到威胁。此外，本研究表明，半结构化访谈与问卷调查相结合，有助于收集特定植物群的民族植物学数据。采用色谱指纹图谱和宏观性状相结合的方法对市售药材进行了植物性鉴定，验证了同音字花khao-yen药材的植物性。结果表明，花khakhayen nuea和花khakhayen tai药材的来源分别为菝葜(Smilax glabra)和萱草(Premna herbacea)。
