The Philippines is renowned as one of the species-rich countries and culturally megadiverse in ethnicity around the globe. However, ethnopharmacological studies in the Philippines are still limited especially in the most numerous ethnic tribal populations in the southern part of the archipelago. This present study aims to document the traditional practices, medicinal plant use, and knowledge; to determine the relative importance, consensus, and the extent of all medicinal plants used; and to integrate molecular confirmation of uncertain species used by the Agusan Manobo in Mindanao, Philippines. Quantitative ethnopharmacological data were obtained using semi-structured interviews, group discussions, field observations, and guided field walks with a total of 335 key informants comprising of tribal chieftains, traditional healers, community elders, and Manobo members of the community with their medicinal plant knowledge. The use-report (UR), use categories (UC), use value (UV), cultural importance value (CIV), and use diversity (UD) were quantified and correlated. Other indices using fidelity level (FL), informant consensus factors (ICF), and Jaccard’s similarity index (JI) were also calculated. The key informants’ medicinal plant use knowledge and practices were statistically analyzed using descriptive and inferential statistics. This study enumerated the ethnopharmacological use of 122 medicinal plant species, distributed among 108 genera and belonging to 51 families classified in 16 use categories. Integrative molecular approach confirmed 24 species with confusing species identity using multiple universal markers (ITS, matK, psbA-trnH, and trnL-F). There was strong agreement among the key informants regarding ethnopharmacological uses of plants, with ICF values ranging from 0.97 to 0.99, with the highest number of species (88) being used for the treatment of abnormal signs and symptoms (ASS). Seven species were reported with maximum fidelity level (100%) in seven use categories. The correlations of the five variables (UR, UC, UV, CIV, and UD) were significant (rs ≥ 0.69, p < 0.001), some being stronger than others. The degree of similarity of the three studied localities had JI ranged from 0.38 to 0.42, indicating species likeness among the tribal communities. Statistically, the medicinal plant knowledge among respondents was significantly different (p < 0.001) when grouped according to education, gender, social position, occupation, civil status, and age but not (p = 0.379) when grouped according to location. This study recorded the first quantitative ethnopharmacological documentation coupled with molecular confirmation of medicinal plants in Mindanao, Philippines, of which one medicinal plant species has never been studied pharmacologically to date. Documenting such traditional knowledge of medicinal plants and practices is highly essential for future management and conservation strategies of these plant genetic resources. This ethnopharmacological study will serve as a future reference not only for more systematic ethnopharmacological documentation but also for further pharmacological studies and drug discovery to improve public healthcare worldwide.

菲律宾Agusan del Sur的Manobo部落使用的药用植物的定量民族药理学记录和分子确证。

菲律宾被誉为物种丰富的国家之一,在世界范围内种族多元文化。但是,菲律宾的民族药理学研究仍然很有限,尤其是在该群岛南部的大多数民族部落人口中。本研究旨在记录传统做法,药用植物的使用和知识。确定所有药用植物的相对重要性,共识和范围;并整合菲律宾棉兰老岛Agusan Manobo使用的不确定物种的分子确认。使用半结构化访谈,小组讨论,实地观察和指导的实地走访获得了定量的民族药理学数据,共有335名主要信息提供者,包括部落首领,传统医士,社区长者,和社区的Manobo成员,他们具有药用植物知识。对使用报告(UR),使用类别(UC),使用价值(UV),文化重要性值(CIV)和使用多样性(UD)进行了量化和关联。还使用保真度水平(FL),知情同意因子(ICF)和Jaccard相似度指数(JI)计算了其他指数。使用描述性和推论统计对主要被告人的药用植物使用知识和实践进行了统计分析。这项研究列举了122种药用植物的民族药理学用途,分布在108个属中,属于16个使用类别中的51个科。整合分子方法使用多种通用标记(ITS,matK,psbA-trnH和trnL-F)确认了具有混淆性的24种物种。关键知情者之间就植物的民族药理用途达成了高度共识,ICF值介于0.97至0.99之间,用于治疗异常体征和症状(ASS)的物种数量最多(88)。据报告,在七个用途类别中,有七个物种的保真度最高(100%)。五个变量(UR,UC,UV,CIV和UD)的相关性显着(rs≥0.69,p <0.001),其中一些变量比其他变量强。三个研究地点的相似度JI在0.38至0.42之间,表明部落社区之间的物种相似。从统计学上讲,按教育程度,性别,社会地位,职业,公民身份和年龄分组时,受访者的药用植物知识差异显着(p <0.001),但没有差异(p = 0)。379)根据位置分组。这项研究记录了菲律宾棉兰老岛第一个定量的民族药理学文献,并对药用植物进行了分子确证,迄今为止,尚未对其中一种药用植物进行药理研究。记录此类药用植物和实践的传统知识对于这些植物遗传资源的未来管理和保护策略至关重要。这项民族药理学研究将为将来提供参考,不仅为更系统的民族药理学文献提供参考,而且还将为进一步的药理学研究和药物发现提供参考,以改善世界范围内的公共卫生保健。这项研究记录了菲律宾棉兰老岛第一个定量的民族药理学文献,并对药用植物进行了分子确证,迄今为止,尚未对其中一种药用植物进行药理研究。记录此类药用植物和实践的传统知识对于这些植物遗传资源的未来管理和保护策略至关重要。这项民族药理学研究将为将来提供参考,不仅为更系统的民族药理学文献提供参考,而且还将为进一步的药理学研究和药物发现提供参考,以改善世界范围内的公共卫生保健。这项研究记录了菲律宾棉兰老岛第一个定量的民族药理学文献,并对药用植物进行了分子确证,迄今为止,尚未对其中一种药用植物进行药理研究。记录此类药用植物和实践的传统知识对于这些植物遗传资源的未来管理和保护策略至关重要。这项民族药理学研究将为将来提供参考,不仅为更系统的民族药理学文献提供参考,而且还将为进一步的药理学研究和药物发现提供参考,以改善世界范围内的公共卫生保健。记录此类药用植物和实践的传统知识对于这些植物遗传资源的未来管理和保护策略至关重要。这项民族药理学研究将为将来提供参考,不仅为更系统的民族药理学文献提供参考,而且还将为进一步的药理学研究和药物发现提供参考,以改善世界范围内的公共卫生保健。记录此类药用植物和实践的传统知识对于这些植物遗传资源的未来管理和保护策略至关重要。这项民族药理学研究不仅可以作为将来系统参考的民族药理学文献的参考,而且可以为进一步的药理学研究和药物开发提供参考,以改善世界范围内的公共卫生保健。
