Study on the IR fingerprint of Chinese medicinal granule / 中成药

ABSTRACT

Objective: To identify the Chinese medicinal granule (CMG) by measuring IR fingerprints. Methods: 12 species drugs were extracted with butanone respectively and then the obtained extracts were measured by the FT-IR spectrometer. Results: By IR fingerprint of 12 kinds of CMG, we found that different batches of the same CMG had a stable and repeatable fingerprint. Conclusion: By using IR fingerprint, CMG can be identified. It provides a rapid monitoring for drug identification and quality control.
