The stem bark and leaves of Daniellia oliveri were obtained from two sites, Batsari and Zurmi, in Nigeria. Leaves of Leptoderris micrantha were obtained from Agbagi, Nigeria. Essential oils of these plants were obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The major components in the bark essential oil of D. oliveri were δ-cadinene (12.8%), α-muurolene (6.7%), α-calacorene (5.9%), and caryophyllene oxide (5.5%). The major components in the leaf essential oils from Batsari and Zurmi, respectively, were humulene epoxide II (8.0% and 16.3%), caryophyllene oxide (7.4% and 12.4%), pentadecanal (8.9% and 6.0%), phytone (6.5% and 2.2%), δ-cadinene (5.3% and 3.0%), and α-muurolene (5.3% and 2.6%). The major components in the leaf essential oil of L. micrantha were incensole (16.2%), phytone (15.4%), pentadecanal (13.7%), α-pinene (7.7%), and iso-phytol (5.2%). The essential oils were screened for antibacterial activity against Bacillus cereus, Cutibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Pseudomonas aeruginosa, and Serratia marcescens, and for antifungal activity against Aspergillus fumigatus, Aspergillus niger, Cryptococcus neoformans, Microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes, Trichophyton rubrum, and Candida albicans, using the microbroth dilution method. The leaf essential oils of D. oliveri and L. micrantha showed only marginal activity against the panel of microorganisms. However, D. oliveri bark essential oil showed notable antifungal activity against Aspergillus niger and Trichophyton rubrum with a minimum inhibitory concentration of 78.1 µg/mL for each. This is the first report on the essential oil compositions of D. oliveri and L. micrantha from Nigeria and their antimicrobial activities.

Daniellia oliveri的茎皮和叶子是从尼日利亚的Batsari和Zurmi的两个地点获得的。叶Leptoderris金菊从Agbagi，尼日利亚获得。这些植物的精油通过加氢蒸馏得到并通过气相色谱-质谱法分析。D. oliveri树皮精油中的主要成分分别是δ-卡丁烯（12.8％），α-茂木烯（6.7％），α-cal草烯（5.9％）和石竹烯氧化物（5.5％）。来自Batsari和Zurmi的叶片精油中的主要成分分别为humulene环氧化合物II（8.0％和16.3％），石竹烯氧化物（7.4％和12.4％），十五烷（8.9％和6.0％），植酮（6.5％）和2.2％），δ-二氢化茚（5.3％和3.0％）和α-茂苯（5.3％和2.6％）。薇甘菊叶片精油中的主要成分是香茅酚（16.2％），植酮（15.4％），十五烷（13.7％），α- pine烯（7.7％）和异植醇（5.2％）。筛选了精油对蜡状芽孢杆菌，痤疮杆菌，金黄色葡萄球菌，表皮葡萄球菌的抗菌活性。，化脓性链球菌，铜绿假单胞菌，和粘质沙雷氏菌，以及针对抗真菌活性烟曲霉，黑曲霉，新型隐球菌，犬小孢子菌，小孢子gypseum，须发癣菌，深红色发癣菌，和白色念珠菌，采用微量肉汤稀释法。D. oliveri和L. micrantha的叶片精油仅对微生物群表现出很小的活性。但是，D。Oliveri树皮精油对黑曲霉和毛癣菌表现出显着的抗真菌活性，最低抑菌浓度分别为78.1 µg / mL。这是关于尼日利亚D. Oliveri和L. micrantha的精油成分及其抗菌活性的首次报道。
