A suitable ehro- matographic system was established using a linear gradient elution with acetonitrile and 0.1% phosphoric acid (H3PO4) as the mobile phase and a detection wavelength of 210 nm. HPLC analysis identified 12 common peaks and 8 common fingerprint peaks among the different parts of the herb. We found that the constituents varied at different harvesting times and in different parts of the plant. The HPLC fingerprint method could be used to evaluate the quality ofM. suaveolens Ledeb and Melilotus genus herbs. The same strategy can also be applied for the development of fingerprints for the quality control of other herbal medicines.展开更多
