根据其物理和光谱性质（MS、NMR、IR和UV），鉴定了myoga（米奥加）的辛辣成分为（E）-8 β（17）-epoxylabd-12-ene-15，16-dial（米奥加醛）。Galanal A和B，分离以及miogadial，没有辛辣的味道。减少miogadial也无味。辛烯醛的辛味主要取决于辛烯醛中不饱和的1，4-二醛基。
The pungent principle of myoga (Zingiber mioga Roscoe) was identified as (E)-8beta(17)-epoxylabd-12-ene-15,16-dial (miogadial) on the basis of its physical and spectroscopic properties (MS, NMR, IR, and UV). Galanal A and B, isolated as well as miogadial, had no hot taste. Reduced miogadial also was tasteless. The pungency of miogadial depended on the presence of alphabeta-unsaturated-1,4-dialdehyde group.
