    Abstract:
    OBJECTIVE: To establish a HPLC method for simultaneous determination of four major constituents (madecassoside, asiaticoside, madecassic acid and asiatic acid) in Centella asiatica (L.) urban extracts. METHODS: The analysis was performed on an Agilent 1100 HPLC system with a ZORBAX Eclipse XDB-C8 column (4.6 mm×150 mm, 5μm). The four major constituents were separated with gradient mobile phase that consists of 1mmol/L potassium dihydrogen phosphate and acetonitrile at the detection wavelength of 205 nm. RESULTS: The four major constituents all had good linear response in the determination ranges (R(2)≥0.9998). The average recoveries (n=9) were 97.4%, 93.7%, 97.5% and 99.8% with RSDs of 3.4%, 1.4%, 4.7% and 4.4%, respectively. CONCLUSION: The developed method is sensitive and has good reproducibility, which can be used as a reference for quality control of Centella asiatica (L.) urban extracts.
