　　以灵台牛心杏为研究对象，用3种中药材的乙醇提取液与基质液配伍成涂膜保鲜剂，在温度为-1℃～0℃、相对湿度为80％～90％的条件下贮藏牛心杏，比较对其贮藏品质和生理生化指标的影响.结果表明：以2.0mg/ml连翘、1.5mg/ml丁香、1.5mg/ml川芎提取液涂膜处理牛心杏后，可延缓牛心杏果实的衰老和品质的劣变，大大减少牛心杏果实的失重率、腐烂率，减缓可溶性固形物含量、可滴定酸含量、VC含量的下降速度；并对牛心杏相对电导率、PPO的活性的有较强的抑制抑制作用，与1-MCP(对照)无明显差异(P>0.05)；而保持牛心杏果实CAT、POD较高活性，能有效清除牛心杏果实衰老自由基，对牛心杏有很好的保鲜效果.
