Pharmaceutical dosage forms containing gelatin are recently of high attention in regard to its porcine content. In Muslim countries, halal products assurance is strictly regulated, not only for food but also for pharmaceutical products. This study aimed to develop gelatin identification and verification method in capsule shells by performing simple simultaneous protein- and nucleic acid based-identification methods. Identification and verification performing polyacrylamide gel electrophoresis (PAGE)?coupled with principle component analysis, and polymerase-chain-reaction (PCR)-restriction fragment length polymorphism (RFLP) were carried out. Gelatin was obtained by extracting the capsules using cold acetone; the precipitate was used directly for PAGE, and was used as well for DNA extraction. The results showed that the porcine gelatin reference showed 12 major bands of peptide profile, with predominant bands at ±200 and ±100?135 kDa on 8 % Tris-glycine gel, while bovine gelatin only showed four major bands. Further, PCR-RFLP result showed two specific bands of the porcine gelatin DNA at 228 and 131 bp, whereas the bovine gelatin DNA bands occurred at 316 and 44 bp. The results demonstrated that the capsule shell samples used in this study contained the following: sample 1 was verified contain porcine gelatin, whereas the three other samples identified contain bovine gelatin. Although the simultaneous approaches seemed need to be improved, it is crucial to maintain their low cost and simple protocol.
