Development And Validation

Abstract An easy and simple analytical method was standardized and validated for the estimation of residues of spirotetramat and its metabolite spirotetramat cis enol in various substrates: okra fruits, brinjal leaves and fruits, green chili, red chili, and soil. The samples were extracted with acetonitrile, diluted with brine solution, partitioned into dichloromethane, dried over anhydrous sodium sulfate, and cleaned up by treatment with activated charcoal powder. Final clear extracts were concentrated under vacuum and reconstituted with HPLC grade acetonitrile. Residues were estimated using HPLC with a photodiode array detector and a C18 column, and confirmed by HPTLC. Acetonitrile was used as the mobile phase at 0.4 mL/min. Both spirotetramat and spirotetramat cis enol presented distinct peak at retention times of 8.518 and 7.598 min, respectively. Consistent recoveries ranging from 82 to 97% for spirotetramat and spirotetramat cis enol were observed when samples were spiked at 1.00 to 0.03 mg/kg levels. The LOQ of the method was found to be 0.03 mg/kg. The analytical method was validated in terms of parameters, including selectivity, linearity, precision, and accuracy.

Stability indicating RP-UPLC photo diode array detector based method for determination of Dapagliflozin propanediol monohydrate (DPM) in active pharmaceutical ingredient (API) and in tablet dosage form (5mg dapagliflozin) has been developed and validated on Bridge Ethylene Hybride (BEH) C18 column (50mm × 2.1 mm, 1.7µm). Mobile phase composition was water: acetonitrile (60:40 v/v), flow rate 0.5ml/min and detection carried out at 223nm at column temperature 30ºC. Chromatographic separation achieved within 2 min with retention time 0.77 min. Linearity of the method was found over the concentration range of 25-75µg/ml (R2 = 0.9977). The degradation was carried out in five different stress conditions. The developed method was able to resolve peak of API from all generated peaks. Sufficient degradation was achieved in the range of 5.25 to 12.31%. The peak purity is acceptable, Method validation was performed as per ICH guideline Q2(R1).
