| 摘 要： | 采用毛细管气相色谱-质谱仪，考察了怀山药在300、400、450及500℃下的热解反应．对怀山药的热解产物进行了分析，首次发现山药热解产物中含有咖啡因成分．确证咖啡因成分是山药中化学成分裂解所产生的． |
| 关 键 词： | 怀山药 热解 毛细管气相色谱-质谱 咖啡因 |

| Abstract: | Capillary gas chromatography/mass spectroscopy was used to analyze the components produced by heating the crude drug of Huai Shanyao(Dioscorea opposite Thunb.) at 300,400,450 and 500 ℃,respectively.Caffeine was detected from the pyrolyzed component of the crude drug Huai Shanyao,which was firstly identified and confirmed in the components produced by heating the crude drug of Huai Shanyao. |
| Keywords: | dioscorea opposita thunb pyrolysis capillary gas chromatography-mass spectroscopy caffeine |
