The ethanolic extracts of twelve plants selected through ethnomedical survey in Guinea-Bissau were investigated for their in vitro antimicrobial properties over ten bacteria and Candida albicans, using agar diffusion and dilution methods. All the tested extracts showed some activity against at least one of the bacteria. Most of the extracts (79%) showed activity against Staphylococcus aureus and only one (Cryptolepis sanguinolenta) against Escherichia coli. Cryptolepis sanguinolenta and Terminalia macroptera root extracts showed some activity against Candida albicans as well as showing an interesting profile of activity against most of the enteropathogen microorganisms. Inhibition zones against Staphylococcus aureus were localised on extract chromatograms by bioautographic techniques.
通过在几内亚比绍进行的民族医学调查挑选出12种植物，采用琼脂扩散法和稀释法，研究了它们的乙醇提取物对10种细菌和白色念珠菌的体外抗菌特性。所有受试提取物均对至少一种细菌表现出一定活性。大多数提取物（79%）对金黄色葡萄球菌有活性，只有一种提取物（红血龙血树）对大肠杆菌有活性。红血龙血树和大翅榄仁树根提取物对白色念珠菌表现出一定活性，并且对大多数肠道病原微生物也呈现出有趣的活性特征。通过生物自显影技术在提取物色谱图上确定了对金黄色葡萄球菌的抑菌圈。
