  • Title: Packed column chromatography, high-resolution gas-chromatography and high pressure liquid chromatography in comparison for the analysis of cannabis constituents.
    Author: Barni Comparini I, Centini F.
    Journal: Forensic Sci Int; 1983; 21(2):129-37. PubMed ID: 6301960.
    Abstract:
    The identification and the quantitative estimation of cannabis constituents is important for forensic purposes. High resolution gas-chromatography gives better results than gas-liquid chromatography with packed columns, as it shows a better resolution and higher number of constituents. Different quantitative values were found with the two chromatographic procedures. High-pressure liquid chromatography revealed the presence of cannabinoid acids in fresh cut influorescences of cannabis plants. The ratio acid/neutral cannabinoid may be useful in supplying information about the age of the cannabis preparations.
