The fungus growing termite species () is used in nutrition and traditional medicine in the Republic of Benin for the treatment of infectious and inflammatory diseases. Previous findings demonstrated evidence of anti-inflammatory and spasmolytic properties of . The aim of the present study was to evaluate the antimicrobial potential of different extracts of samples and determine the chemical profile of an ethanolic extract. Chemical profiling was conducted using centrifugal partition chromatography and C-NMR, followed by MALDI-TOF MS. Major identified compounds include hydroquinone (HQ), methylhydroquinone (MHQ), 3,4-dihydroxyphenethyl glycol (DHPG), -acetyldopamine (NADA) and niacinamide. The fatty acid mixture of the extract was mainly composed of linoleic and oleic acid and highlights the nutritional purpose of . Using the Kirby-Bauer disc diffusion and broth microdilution assay, an antibacterial activity of samples was observed against various clinical strains with a highest growth inhibition of . In addition, HQ and MHQ as well as fractions containing DHPG, niacinamide and NADA inhibited growth. The reported antimicrobial activity of and identified active substances provide a rationale for the traditional medicinal use of .
在贝宁共和国,生长真菌的白蚁物种()被用于营养和传统医学,以治疗感染和炎症性疾病。先前的研究结果表明具有抗炎和松弛平滑肌的特性。本研究旨在评估不同()样本提取物的抗菌潜力,并确定其乙醇提取物的化学特征。采用离心分配色谱和 C-NMR 进行化学特征分析,随后采用 MALDI-TOF MS。主要鉴定的化合物包括对苯二酚(HQ)、间苯二酚(MHQ)、3,4-二羟基苯乙基二醇(DHPG)、-乙酰多巴胺(NADA)和烟酰胺。提取物的脂肪酸混合物主要由亚油酸和油酸组成,突出了()的营养价值。采用 Kirby-Bauer 圆盘扩散和肉汤微量稀释法,观察到()样品对各种临床菌株的抗菌活性,对的生长抑制率最高。此外,HQ 和 MHQ 以及含有 DHPG、烟酰胺和 NADA 的馏分也抑制了的生长。()的报道抗菌活性和鉴定的活性物质为其传统药用提供了依据。
