探讨以水作溶剂对车前子进行提取的条件.通过正交实验方法确定车前子的水提取最佳条件:提取时间 30 min,加水比 10:1,提取温度 100℃;同时试验了不同粉碎度及提取方式对提取率的影响,并开发研制出车前子冲剂.

The optimal conditions for the water extraction of the seed of Plantago asiatica L.were studied by orthogonal experimental design. Results showed that extraction with a 10∶1 water:seed ratio at 100℃ for 30 min gave the best result. It was also found that 30 mesh was the most preferable degree of fineness of the seed. The extract was processed into a granular dosage form for development.
