The volatile compounds of "YongFang F pearl cream" were absorbed by coated wire, and analyzed by GC-9A chromatography. The results of 24 true products were studied by using R-type cluster and factor analysis, and 14 features were extracted. The mathemati cal pattern of identifying true of false of "YongFang" was established by Q-type cluster. It is satisfactory that the pattern was verified by testing 3 false and 2 true products.
