The essential oils of aegle, ageratum, citronella, eucalyptus, geranium, lemongrass, orange, palmarosa, patchouli and peppermint, were tested for antibacterial activity against 22 bacteria, including Gram-positive cocci and rods and Gram-negative rods, and twelve fungi (3 yeast-like and 9 filamentous) by the disc diffusion method. Lemongrass, eucalyptus, peppermint and orange oils were effective against all the 22 bacterial strains. Aegle and palmarosa oils inhibited 21 bacteria; patchouli and ageratum oils inhibited 20 bacteria and citronella and geranium oils were inhibitory to 15 and 12 bacterial strains, respectively. All twelve fungi were inhibited by seven oils (aegle, citronella, geranium, lemongrass, orange, palmarosa and patchouli). Eucalyptus and peppermint oils were effective against eleven fungi. Ageratum oil was inhibitory to only four fungi tested. The MIC of eucalyptus, lemongrass, palmarosa and peppermint oils ranged from 0.16 to > 20 microliters ml-1 for eighteen bacteria and from 0.25 to 10 microliters ml-1 for twelve fungi.
采用纸片扩散法，对木苹果、藿香、香茅、桉叶、天竺葵、柠檬草、橙子、玫瑰草、广藿香和薄荷的精油进行了抗菌活性测试，受试对象包括22种细菌（革兰氏阳性球菌和杆菌以及革兰氏阴性杆菌）和12种真菌（3种酵母样真菌和9种丝状真菌）。柠檬草、桉叶、薄荷和橙子精油对所有22种细菌菌株均有抗菌效果。木苹果和玫瑰草精油抑制了21种细菌；广藿香和藿香精油抑制了20种细菌，香茅和天竺葵精油分别抑制了15种和12种细菌菌株。所有12种真菌均被7种精油（木苹果、香茅、天竺葵、柠檬草、橙子、玫瑰草和广藿香）抑制。桉叶和薄荷精油对11种真菌有效。藿香精油仅对4种受试真菌有抑制作用。桉叶、柠檬草、玫瑰草和薄荷精油对18种细菌的最低抑菌浓度范围为0.16至>20微升/毫升，对12种真菌的最低抑菌浓度范围为0.25至10微升/毫升。
