目前,常用木材化学防腐剂会给环境带来很重的负担,尽快研发出绿色环保的木材防腐剂显得尤为重要。选用纯天然的中草药配制成木材防腐剂是针对目前化学防腐剂的环境问题提出的,通过FTIR研究四种对木材白腐菌有抑制作用的中药的活性成分,从而为制备绿色环保木材防腐剂提供理论依据。根据蛇床子、苦参、连翘、黄连4种中药中有效成分的不同性质,使用不同的有机溶剂萃取其中的有效成分,通过红外光谱和其中有效成分含量的测定来确定中药当中能够起到抑菌的具体成分。得到以下的结论:在蛇床子当中能够起到抑制白腐菌作用的成分为蛇床子素;苦参有效成分当中,能够起到抑菌作用的为苦参碱;黄连当中能够起到抑菌作用的有两种成分,一种为盐酸小檗碱,另一种为巴马丁等的混合物,对此有待于以后进一步的研究;连翘当中能够起到抑制白腐菌作用的主要为连翘苷。
At present, the commonly used wood chemical preservatives will bring a heavy burden on the environment. It is particularly important to develop green and environmental preservatives as soon as possible. The selection of pure natural Chinese herbal medicine as a wood preservative is based on the current environmental problems of chemical preservatives proposed by FTIR four kinds of wood white rot fungi inhibition of the active ingredients of traditional Chinese medicine to prepare for the preparation of green wood preservatives Theoretical basis. According to the different properties of the effective components in the four Chinese traditional medicines of Cnidomegaly, Sophora flavescens, Forsythia suspense and Coptis chinensis, different organic solvents were used to extract the active ingredients thereof, and the content of the active ingredients thereof was determined by infrared spectroscopy Specific components of bacteria. Obtained the following conclusions: among the Cnidium can play a role in inhibiting white rot fungi osthol component; Sophora active ingredients, which can play an inhibitory effect of matrine; Coptis can play an antibacterial effect There are two components, one is berberine and the other is a mixture of parmatide and so on, which needs further study; Forsythia can play a role in inhibiting white rot fungi mainly forsythin .
