Abstract
A simple high performance liquid chromatographic (HPLC) method for determining thiabendazole in fruits was developed. Thiadazole is extracted with methanol and the extract is washed with n-hexane saturated with methanol. The determination is carried out by HPLC with fluorometric detection. LiChrosorb RP-8 is used as the stationary phase and methanol-0.28% ammonia water (60 + 40) as the mobile phase; .alpha.-methylindole is added as an internal standard. The limit of detction of this method is 0.1 .mu.g thiabendazole/g. Recoveries are more than 92%.
