摘要：

The classification of hashish was studied by pyrolysis-gas chromatography. To estimate the route through which they had been obtained by suspects, detailed classification of samples of hashish was performed using cluster analysis after normalization of the peaks in the pyrograms against the highest peak in each pyrogram. The results of cluster analysis were presented as a dendrogram, an easily interpreted visual representation of the similarity among samples, The 13 different samples collected were roughly divided into two groups. The observed datum for an unknown sample was evaluated by comparison with the known samples and classified into one of the groups. The dendrogram proved to be effective in discriminating between hashish obtained from different sources.
