n.胡蘿卜烷

Through the pyrolysis experiments，it is discovered that the carotane formation demands ample reductant. 含有飽和環(huán)的甾萜類是良好的還原劑。

The formation of carotane is the result of the hydrogen addition of carotene，and this process is very typical redox reaction，which needs plenty of hydrogen . 即使環(huán)境并非屬于氧化,如果缺乏還原劑,胡蘿卜素也不能轉(zhuǎn)化成胡蘿卜烷;
