“…It is good news regarding subsequent data treatment. Again with cocaine it is often advocated that benzoylecgonine is the major hydrolysis product of cocaine and can be formed during inadequate cocaine storage or due to aging process [15] and influence the similarity measurement. This could be problematic for comparison purpose; therefore we have evaluated 3 scenarios for investigating this aspect.…”

“…Since the first cocaine sample chromatography in 1962 by Brochmann-Hanssen [6] with a non polar stationary phase, many columns and chromatography techniques were tested in order to analyse cocaine in plant material or in powder samples to understand its production [7,8]. The literature describes different classes of compounds that could be used for the determination of chemical profiles.…”

Cloud point extraction process using non-ionic surfactant, Triton X-114, to extract codeine from aqueous solution was investigated. The method was based on the extraction of codeine and bromothymol blue from acetate buffer media to surfactantrich phase and formed a charge transfer-ion pair complex. The extracted surfactant-rich phase was diluted with ethanol and its absorbance was measured at 430 nm. The effect of different variables such as pH, Triton X-114 concentration, cloud point temperature and time was established. The calibration graph was linear in a wide range of 100 -700 ng ml -1 of codeine with r = 0.998 (n = 7). The detection limit based on three times standard deviation of the blank (3s) was 4.6 ng ml -1 and relative standard deviation (R.S.D) is 2.15% for 500 ng ml -1 codeine (n = 5). The proposed method was applied to the determination of codeine in acetaminophen codeine tablets and blood samples.
