摘要
以安徽菌启健公司的商陆为试验原材料,采用水提法提取商陆浸提液.用商陆水提液开展对常见霉菌抑制作用的实验.实验表明:在10～100 g/L浓度范围内,哈茨木霉的菌落直径由 17.27 mm降至 11.14 mm;层出镰孢菌的菌落直径由17.07 mm降至11.07 mm;茄腐镰刀菌的菌落直径由16.17 mm降至10.23 mm,其最佳抑制浓度为100 g/L.实验结果发现商陆水提液对哈茨木霉菌、层出镰孢菌、茄腐镰刀菌三种菌有较好的抑菌效果,其抑菌率分别为53.43%(哈茨木霉菌)、53.25%(层出镰孢菌)、59.37%(茄腐镰刀菌).实验结果表明:一定浓度的商陆水煮提取液能有效抑制哈茨木霉菌、层出镰孢菌、茄腐镰刀菌的生长,在防霉实践中具有潜在应用前景.
Abstract
Phytolacca acinosa Roxb was bought from Anhui Junqi Health Technology Company,and P.acinosa ex-tract was obtained by water extraction.The anti-mold experiments were carried out,and the results showed that un-der the extract concentration of 10 g/L to 100 g/L,the colony diameter of Trichoderma harzianum decreased from 17.27 mm to 11.14 mm,that of Fusarium proliferatum decreased from 17.07 mm to 11.07 mm,and that of Fusari-um solani decreased from 16.17 mm to 10.23 mm.The best inhibitory effect was achieved under the concentration of 100 g/L.The inhibition rates were 53.43%(T.harziamum),53.25%(F.proliferatum),and 59.37%(F.solani),respectively.In conclusion,P.acinosa water extract at a certain concentration could effectively inhibit the growth of T.harziamum,F.proliferatum and F.solani,showing potential application prospect in anti-mold practice.
