<p><b>UNLABELLED</b>To study the effect of S-3307 on the yield and main ingredients of Alisma plantago-aquatica.</p><p><b>METHOD</b>The contents of 24-acetyl alisol A and the 23-acetyl alisol B in tuber were determined by HPLC.</p><p><b>RESULTS</b>The contents of 24-acetyl alisol A and the 23-acetyl alisol B as well as yield were significantly increased in all groups applied with different concentrations of S-3307 comparing with control group. The optimal concentration of S-3307 was 80 mg x kg(-1). The residues of S-3307 was detected under 0.316 8 mg x kg(-1) (detecting limit).</p><p><b>CONCLUSION</b>The optimal concentration of S-3307 is 80 mg x kg(-1), it reached the best result when applied 36 d after seedling.</p>
