Abstract

The UV-spectra-shifting of allobarbital, barbital, butalbital and phenobarbital on AL-TLC-Si gel 60 F254under exposed different pH eluent, drying TLC-plat at 110oC, and then plat placed at room temperature for morethen 17 hours has been carried out. Spectra UV were read by using TLC-Scanner 3 –Camag-Muttenz-Switzerland between 190 and 300 nm. Aim of this research was to study UV-spectra-shifting which can conducterror by confirmation test using in situ UV spectra.There was no significant UV-spectra-shifting of barbiturate on TLC-plate after exposed by mobile phase:10% HCl in methanol (pH=1), chloroform-acetone (80:20, v/v, pH=5), methanol-n-buthanol (60:40, v/v, pH=6),methanol-ammonia (100:1,5, v/v, pH=10) respectively. The significant shifting of UV spectra were obtainedafter TLC-plate exposed by cyclohexane-toluene-diethyl amine (75:15:10, v/v, pH=11) and 0,1 M KOH inmethanol (pH=12), the spectrum shifting was 66% and 23% compared with spectra at pH=1. Drying of the TLCplatesafter exposed by mobile phase conducted no significant UV-spectra shifting, except after exposed bycyclohexane-toluene-diethyl amine (the shifting was 45%). Humidity absorption while placing the TLC-platesat room temperature for more then 17 hours after exposed by strong pH base lead the shifting UV-spectra ofbarbiturate to the weak base or neutral spectra. These shifting UV-spectra should be taken in consideration onconfirmation test of barbiturate based TLC-UV in-situ spectra to reduce error.

Abstract

The seizures ecstasy tablets from Bali have been physical and chemical profiled. The physical characteristic of the tablets was assessed and documented. The chromatographic fingerprint has been carried out with help of the HPTLC-densitometric and the solvent of TB (cyclohexane-toluene-diethylamine, 25:3: 1 v/v). The single linkage clustering method grouped the fingerprints. Based on the physical properties, the tables were divided into 19 groups and the multivariate analysis was clustered the tablets info 6 groups based on their chemical content relationship. The amphetamine type stimulant (ATS) substances were identified in 87% of the tablets. The ATS were methylene-dioxy-methamphetamine (MDMA), methylene-dioxy-amphetamine (MDA), and ketamine. The caffeine, piperazine, and clorquinon were the chemical adjuvant, which added into the tablets. The physical and chemical profiling could be helped the authority the trace their distribution network.
