以麻竹叶为材料,以干燥方法、溶剂浓度等为试验因素,用正交试验方法,选取了较优处理组合,进行了提取条件对提取率和提取物抑菌影响的试验.结果表明:40℃热风干燥提取率为7.36%,太阳晒后阴干为7.08%,室温晾干为6.97%,太阳晒干燥为6.50%;60%乙醇提取液对细菌的抑制效果最好,40℃热风干燥抑菌力最强,对大肠杆菌的抑菌圈直径为12.70 mm,太阳晒后阴干次之,为11.27 mm,室温晾干较弱,为11.13 mm,太阳晒干燥最弱,为10.40 mm.正交试验结果:液料比12∶l、浸提温度80℃、时间1.5 h为最佳提取工艺条件,在此条件下的提取率为7.74%.

The effect of extract condition on extract ratio and restraining bacteria was tested, using Sinocalamus latiflorus as material. The results show that drying in the wind of 40℃, drying in the shade, airing in room temperature and drying in the sun, the extract ratios are 7.36%, 6.97% and 6.50% respectively. Liquid extracted by 60% alcohol and material drying in the wind of 40℃ have the best effect on restraining bacteria. The optimal processing condition is that ratio of liquid and material is 12:1, and extract temperature is 80℃...
