Abstract
The correlation between the quality and constituents of various kinds of agalwood, obtained in Hong Kong market at the same time was investigated by the dualwavelength thin layer chromatography scanner comparing with the standard samples of 2-(2-phenylethyl) chromone derivatives, AH1 (agarotetrol) and AH2 (isoagarotetrol). It was inapplicable to use AH3, AH4, AH5, and AH6 owing to their low content, but the total content of AH1 and AH2 was relative to the grading of agalwood obtained in the market with few exceptions. The remarkable property of the agaiwood named “Kananko” which has been dealt in on the market at the top price was indicated with very high integrated value obtained by the scanning at the wave1ength ofλs 270 and λR 400 nm, suggesting a great quantity of other constituents di fferent from chromone derivatives.
