				        	Object  To determine the change of benzoic acid contents in decoctions prepared from various combinations of the recipe named SIWUTANG by RP  HPLC to provide a reference for the control of the acid level   Methods  8 decoctions of P   lactiflora either alone or in combination with one or more of the other 3 components, according to permutation and combination, were prepared and their benzoic acid contents determined by RP  HPLC   Results  The content of benzoic acid in the decoction of Radix Paeonie Alba alone was found to be 2  74 mg/g, while that of the other 7 combinations varied from 0  41~1  11 mg/g   Conclusion  The content of benzoic acid in SIWUTANG could be lowered significantly by the presence of Radix Angelica Sinensis, Radix Rehmanniae, and Rhizoma Chuanxiong
