主要成分

Ginger's pungency mainly comes from chemicals such as gingerols ([6]-, [8]-, [10]-gingerol), shogals ([6]-, [8]-, [10]-shogaol). Of those, [6]-gingerol and [6]-shogaol are present in the largest amounts, and are the main active pharmacological ingredients in ginger as well. Gingerols, with the amount directly proportional to the age of the ginger, are thermally unstable, and at high temperatures change easily into shogaols.

姜辛辣味的化学成分主要是gingerols（[6]-， [8]-， [10]-gingerol）、shogals（[6]-， [8]-， [10]-shogaol）其中又以[6]- gingerol、[6]-shogaol的含量最多，也是姜的主要药理活性成分。gingerols具热不安定性，在高温下会变化成shogaols，因此，生姜富含[6]- gingerol，乾姜富含[6]-shogaol，且其量与生长年数成正比。
