Determination of sYP-Z048 Residue in Tomato fruit by HPLC

[aims] sYP-Z048 residue in tomato fruit was determined by high performance liquid chromatography(hPlc).[Methods] samples of tomato fruit were extracted with ethyl acetate,cleaned up by c18-sPe column and analysed by high performance liquid chromatograph combined with UV detector.[Results] The calibration curve was linear in the range of 0.5-100 mg/l,the correlation coefficient(r) was 0.9999.The recovery rate ranged from 88.69 to 96.82%,and the RSD were 2.21-3.03%.The quantification limit(LOQ) of SYP-Z048 in tomato fruit was 0.01 mg/kg.[Conclusions] The method was shown to be simple,rapid and practical.
