1.The results suggest that in the medium eight kinds of moulds,antibiotic activities in turn decrease on citral, citronellal,litsea cubeba oil, geraniol, linalool and methyl heptenone at a pH of 4.5. The minimum antibiotic concentration of citral is 0.10% but methyl heptenone is 0.40% or forereach 0.40%.
结果表明,在培养基pH4.5时,其抗菌效力从强到弱依次为柠檬醛、香茅醛、山苍子油、香叶醇、芳樟醇、甲基庚烯酮。 柠檬醛对5种霉菌的最低抑菌浓度为0.10%,而甲基庚烯酮对6种霉菌的最低抑菌浓度在0.40%或0.40%以上。
