摘要
研究50种中草药水提取物和乙醇提取物对柑橘溃疡病菌的体外抑制活性.结果表明,山茱萸、诃子、地榆、枳实、蔓荆子、覆盆子和马兜铃7种中草药水提物和乙醇提取物对柑橘溃疡病菌具有明显抑制活性.其中以诃子提取物抑菌效果最好,水提液和醇提液在药物浓度5 g/m L时,抑菌圈直径可达3.8 cm和4.4 cm;地榆、枳实抑菌效果次之.该研究可为开发植物源控制柑橘溃疡病菌杀菌剂奠定基础.
Study on the inhibtory activity of 50 kinds of Chinese herbs water extracts and ethanol extracts against Xanthomonas axonopodis pv. citri from Gannan navel orange. The results showed that 7 kinds of Chinese herbs such as Cornus officinalis Sieb.,Terminalia chebula Retz.,Sanguisorba officinalis Linn.,Citrus aurantium L.,Vitex trifolia Linn.,Lonicera japonica Thunb,Aristolochia debilis Sieb. et Zucc.,had obvious inhibitory activity against Xanthomonas axonopodis pv.
