Abstract:
AIM: To establish the method for identifying the herbs of Curcuma. METHODS: Medicinal materials were extracted by 4 solvents such as,80% ethanol,absolute alcohol,acetone and ether,the extracts were dissolved in CHCl_3 and detected within 400-4 000 cm~(-1) by liquid-film method of FIR spectrophotometry.Comparing absorption maximum of different extractions including the location and intensities of peaks. RESULTS: The FIR spectra of these herbal drugs gave different maximum absorption peaks in number and intensity. CONCLUSION: The method is both simple and accurate and can be used to distinguish four kinds of Curcuma speies.
