Nineteen herbs grown in Japan were subjected to hydrodistillation to obtain hydrosols. GC/MS analysis revealed that volatile constituents of 13 hydrosols including that of Houttuynia cordata were changed markedly, depending on the fresh or dried state of the specimens and the season of collection. Furthermore, the volatile constituents of hydrosols were not found in the ethyl acetate extracts of the parent herbs, suggesting that the volatile constituents were produced from non-volatile precursors by the drying process accompanied with hydrodistillation. The remaining six herbs including Perilla frutescens var. crispa afforded essentially the same composition in the hydrosols of fresh and dried specimens as well as the ethyl acetate extracts, suggesting that the volatile constituents existed as such in the parent herbs were collected by hydrodistillation without thermal effect.
