Study on Infrared Fingerprinting of Hedyotis Hedyotidea(DC.)Merr.
Objective To explore the rapid identification technology of Hedyotis hedyotidea(DC.)Merr.by infrared spectroscopy(IR).Methods The overall analysis of the medicinal materials of Hedyotis hedyotidea(DC.)Merr.was performed by FT-IR.Results The characteristic absorption peaks of IR fingerprint of Hedyotis hedyotidea(DC.)Merr.were obtained as follows:3418,2925,2854,1723,1650,1514,1401,1319,1267,1155,1104,1054,1030,919,811,782,763,664,592,538,520 cm-1.1267,1030 cm-1 and 919 cm-1 were the IR characteristic indicative peaks of ursolic acid,which was one of the analgesic and anti-inflammatory components of Hedyotis hedyotidea(DC.)Merr..The IR similarity among the samples was in the range of 0.9003-0.9895,thus the IR similarity threshold of Hedyotis hedyotidea(DC.)Merr.was proposed as 0.90.Conclusion The FT-IR fingerprint of Hedyotis hedyotidea(DC.)Merr.can provide scientific basis for its rapid identification and quality control.
