【摘要】 采用液体深层发酵的方法获得樟芝发酵全液,以乙醇、酸化萃取手段获得发酵全液醇溶酸性组分ESAC,用气相色谱-质谱联用技术结合红外光谱对醇溶酸性组分进行鉴定,对樟芝醇溶酸性组分进行植物病原菌和医学病原菌的抗菌试验。结果表明,醇溶酸性组分主要含有5-氧-四氢呋喃-2-甲酸、苯乙酸、4-羟基苯乙醇、2,4-二羟基苯基乙基酮、3-甲基-2,4-二羟基乙酰苯、2,3,4-三氟苯甲酸异丙酯、5,7,8-三甲基-6-氧杂萘邻酮基乙酸酯、顺-10-十二碳烯酸四氢吡喃酯。ESAC对金黄色葡萄球菌的抑制效果最强。
【Abstract】 The experienment were carried on to obtain fermentation liquid of mycelium of Taiwanofungus camphorates in the way of Liquid-submerged fermentation and then to extract the ethanol-soluble acid component of the liquid by the means of ethanol and acidified extraction.The ethanol-soluble component was identified by gas chromatography/mass spectrometry and infra-red spectrum,and antibacterial research was studied on plant pathogens and medical pathogens.Through the research,we can find that there we...
