title: [Study on extraction process for psoralen in compound prescription by orthogonal design].
abstract: The study on water volume, extraction time and times for the extraction of psoralen in compound prescription Yiniao Tong capsule has been carried out by orthogonal design. The process condition has been determinated, extracting prescription herbs with water for 3 times(2 hour and 16 time amount of water all told). The determination method used in this experiment was TLC-scanning.
