[Abstract] Objective To establish HPLC-ELSD determination method of the hydrochloric acid stachydrine in Motherwort Fruit. Methods The separation by HPLC-ELSD was performed on Asahipak NH2P 50 4E column （4.6 mm × 250 mm） with acetonitrile-0.2% phosphoric acid solution （84∶16） as mobile phase， 1 mL/min of flow rate and 30℃ of column temperature. Results Hydrochloric acid stachydrine at 0.487-4.383 μg had good linear relationship， r = 0.9999， the average recovery was 97.96%， RSD was 0.92%. Conclusion The method is sensitive， specific， it can be used as quantitative determination method of the hydrochloric acid stachydrine in Motherwort Fruit.
