RESUMEN
<p><b>OBJECTIVE</b>To establish the HPLC fingerprint and determine six kinds of ester-type alkaloids of Radix Aconiti lateralis praeparata slice.</p><p><b>METHOD</b>HPLC analysis was performed on a Phenomenex Gemini C18 (4.6 mm x 250 mm, 5 microm) with 0.04 mol x L(-1) ammonium acetate (adjusted to pH 10.0 with ammonia water)and acetonitrile as mobile phase. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004 AB)was used in data analysis.</p><p><b>RESULT</b>Baifupian, Heifupian from different samples were of high similarity in fingerprint, and the separation of six kinds of ester-type alkaloids was good. Huangfupian and crude aconite root showed significant difference in fingerprint, comparing with Baifupian and Heifupian.</p><p><b>CONCLUSION</b>This method is simple and reliable. The HPLC fingerprint and contents of six kinds of ester-type alkaloids of Radix Aconiti lateralis praeparata slice can be used for their quality control.</p>
