摘要: 测定凤仙花醇提取物不同极性部位中1,4-萘醌类成分指甲花醌(HNQ)、指甲花甲醚(MeONQ)的含量及其抑菌活性,探究不同萃取部位中1,4-萘醌类成分含量与其抑菌活性的关系,明确凤仙花抗真菌的主要活性成分。利用HPLC法测定凤仙花不同极性部位中HNQ、MeONQ的含量及转移率;采用滤纸片扩散法比较不同萃取部位对红色毛癣菌的抑菌活性。结果表明,不同极性部位1,4-萘醌类成分含量:石油醚相>二氯甲烷相>乙酸乙酯相>正丁醇、水相;石油醚部位中HNQ和MeONQ的含量、转移率最高,含量分别为4.20%、39.46%,转移率分别为53.46%和92.52%;其次是二氯甲烷部位,HNQ和MeONQ的含量分别为2.44%、0.38%,转移率分别为17.85%和0.49%;乙酸乙酯、正丁醇和水相基本不含以上两种成分。滤纸片扩散法药敏实验结果显示,抑菌圈直径大小:石油醚相>二氯甲烷相>乙酸乙酯、正丁醇、水相,凤仙花石油醚部位的抑菌圈直径最大,即抑菌活性最强;其次是二氯甲烷部位;而乙酸乙酯、正丁醇和水相均无抑菌活性。实验结果证明,凤仙花粗提物的不同极性部位中HNQ和MeONQ含量与其体外抑菌活性呈显著的正相关性,石油醚部位为凤仙花具有抗真菌活性的有效部位,HNQ和MeONQ是凤仙花体外抗红色毛癣菌的主要活性成分。

Abstract: To determine the content of lawsone (HNQ) and 2-methoxy-1,4-naphthoquinone (MeONQ) and antifungal activities of five polar fractionsof ethanol extracts of Impatiens balsamina L.and analyze relationship between content and antifungal activities,in order to define antifungal active constituents of Impatiens balsamina L.The content and transfer rate of HNQ and MeONQ in different extraction parts was simultaneously determined by using HPLC method.The fungicidal activities of extracts of five fractions against Trichophyton rubrum were studied by filter paper diffusion method.The results showed that the petroleum ether extract showed the highest amount of HNQ and MeONQ,their content were 4.20% and 39.46%,and transfer rate were 53.46% and 92.52%,respectively.Secondly,the dichloromethane extraction,their content of HNQ and MeONQ were 2.44% and 0.38%,and transfer rate were 17.85% and 0.49%,respectively.However,ethtyl acetate,n-butanol and water solvent fractions all were hard to detect HNQ and MeONQ.The results of filter paper diffusion method showed that petroleum ether extract was the best,dichloromethane extraction was low antifungal activities,and the other three phases exhibited no antifungal activities.The results showed that antifungal activities were positively correlated to content of HNQ and MeONQ in different polar parts of Impatiens balsamina L.The content of HNQ and MeONQ the petroleum ether extract was the main antifungal active fractions,HNQ and MeONQ were the main active constituent.
