印楝提取物微囊抑菌性能的研究
首发时间:2017-04-26
摘要:本文采用微波辅助提取法对印楝种子进行活性成分提取,确定了提取条件以及提取率。采用水浴搅拌法制备印楝提取物微囊,通过3D显微镜观察微囊形貌特性。通过体外实验法对印楝提取物及其微囊抑菌性能进行研究。结果显示:印楝提取物在提取温度为50℃,料液比为1:12的条件下,微波提取法的提取率为12.84%。水浴搅拌法能够制备出印楝提取物微囊,但粒径不够均匀。采用牛津杯法对印楝提取物及其微囊的体外抑菌实验表明印楝提取物和印楝提取物微囊都具有抑菌性能,而印楝提取物微囊抑菌性能高于印楝提取物抑菌性能,MUF不具有抑菌性能。因此,利用印楝提取物制备微囊防腐剂是可行的。

Performance of a wood preservative microcapsule based on bioactivities of neem
Abstract:In this papermicrowave extractionwere used to extract the active substance from neem seeds powder. Neem extract microcapsule is made of neem extract and MUF by using water bath mixing method, and 3D microscope was used to determine whether to form under the preparing conditions. The anticorrosive antibacterial property of neem extract and its microcapsule were analyzed in vitro test. Conclusions are as follows:The microwave extraction technology is the best methodat the temperature of 50℃, under the condition of the ratio (powder to ethanol) 1:12, , and its extraction rate is as high as 12.84%. The microcapsule can be formed of neem extracts and melamine modified urea-formaldehyde resin (MUF) with feasible test method-water bath mixing method. The neem extract and its microcapsule can inhibit the white-rot fungus (Coriolus versicolor) from growing to a certain extent. The antibacterial performance of neem extract is weaker than ACQ-B's, but its microcapsule's antibacterial performance is slightly worse than ACQ-B, MUF has no antiseptic antibacterial properties.
