The discrimination of the agricultural origin, especially locally produced or imported from the products such as Ganoderma lucidum, sesame and arrowroot were investigated by using the electronic nose. Volatile components from these products were discriminated by twelve of conducting polymer sensors without any pretreatment. Pattern recognition was carried out. Multiple discriminant analysis showed the difference between imported agricultural product and locally produced ones such as Ganoderma lucidum, sesame and arrowroot. Unknown habitat of sesame and arrowroot could be identified by multiple discriminant analysis whether the imported or the locally produced one.
