The industrial chain of traditional Chinese medicine(TCM)is a complicated process including multiple links.It's very difficult to ensure the quality to be safe,effective,stable and controllable in each link of the whole process,especially in production and circulation of Chinese materia medica.Unfortunately almost all current traceability technologies can only carry production or circulation information without quality data.The success of conversion from chemical fingerprint to two-dimensional barcode has created an opportunity to develop a quality traceability system of TCM.However how to use this technology in circulation and consumed terminal still remains elusive.Thus,this study aims to propose a new solution in order to provide a convenient way to restore the initial chemical fingerprint of TCM.Three herbal medicines were randomly selected and their chemical fingerprints were constructed and converted into 2D barcodes.The smartphone tier application will host the QR codes scanning on Android platforms that provide primary functions including restoring the initial chemical fingerprint of TCM and investigating the differences between different batches of TCM chemical fingerprints.It was demonstrated that the APP can restore the initial scanning results into corresponding batches of TCM chemical fingerprints.There were no significant differences between original and scanned TCM chemical fingerprints.Meanwhile,multiple TCM chemical fingerprint QR codes can be displayed in the same coordinate using this APP and their differences can be shown directly and intuitively.A procedure of quality traceability was also established using smartphone technology.This study demonstrated that smartphone can restore chemical fingerprint of TCM by scanning the QR codes,and maintain consistency with the initial chemical fingerprints.It proved that chemical fingerprint of TCM can be easily generated into QR codes.And the QR codes can also restore the original chemical fingerprints.This research provides consumers an easy and rapid way to trace the quality of traditional Chinese medicine.
