Rushes (Juncus effusus L. var. decipens Buchen.) are the plants of Liliopsida Juncales Juncaceae. The stalk is used as a material of the tatami, and is closely related to the life of the Japanese. Especially, the aroma of rushes is one of most popular aromas in Japan. Now, the underwater shock wave destroys the cell and the anatomy of the plant by the action of the spalling destruction. The shock wave is a high pressure that spreads instantaneously, and its destruction action is more effective than a general static pressure. As a result, the element extraction route from the inside is formed to the cell and the anatomy. Thus, treating the underwater shock wave to rushes as a preprocessing, the aroma is expected to be able to be extracted. In this research, authors report on the attempt of the aroma element extraction from rushes by the underwater shock wave loading. The detonation fuse and the electric were used as sources of 2 kinds of the shock wave.
