Deionized hot water (80°C, 1 liter) was added to 60 g of houji-cha, the leaves were filtered using coarse filter paper after standing for 5 min, and steam distillation was performed under reduced pressure (40°C, 20 mmHg). The steam distillate (500 ml) was passed through a column packed with 10 g of Porapak Q (Waters). Adsorbed compounds were eluted with diethyl ether (50 ml), the elute was dried over anhydrous magnesium sulfate, and the solvent was removed with a rotary evaporator to about 2 ml in volume. Further concentration was carried out with a nitrogen stream to about 10 μl. 2,6-Dimethyl-2,6-octadienes were detected by GC and GC-MS from this concentrate.
