Gaultheria longibracteolata (Ericaceae) has been traditionally used by different linguistic groups in Yunnan Province, China, but it has not been well studied. Through our ethnobotanical study in Lüchun County of Yunnan, we found that this species has multiple traditional uses including food, medicine, and worship. The essential oils from the root, stem, and leaf were investigated by both GC-MS and anti-bacterial assays. The GC-MS study showed that methyl salicylate is the main (>90%) component of the essential oil, and the oil composition extracted from different plant parts showed some similarities. The oil of G. longibracteolata displayed antimicrobial activity against Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus, which is likely due to its methyl salicylate content. Gautheria longbracteolata appears to be a useful natural wintergreen oil substitute, but further studies are needed to develop this product.
长苞鹿蹄草（鹿蹄草科）在中国云南省被不同的语言群体传统使用，但尚未得到很好的研究。通过我们在云南省绿春县的民族植物学研究，我们发现该物种有多种传统用途，包括食品、药物和祭祀。我们通过 GC-MS 和抗菌试验研究了其根、茎和叶的精油。GC-MS 研究表明，水杨酸甲酯是精油的主要（>90%）成分，从不同植物部位提取的油成分显示出一些相似性。长苞鹿蹄草油对大肠杆菌、肺炎克雷伯菌和金黄色葡萄球菌具有抗菌活性，这可能与其水杨酸甲酯含量有关。长苞鹿蹄草似乎是一种有用的天然冬青油替代品，但需要进一步研究来开发这种产品。
