Ginger oleoresin was extracted from Zingiber officinale Rose. var. Laiwudajiang by the technique of supercritical fluid extraction. Gas chromatography and mass spectrometry technique were employed to analyze the ginger oleoresin. This analysis resulted in the detection of 3 hitherto unknown natural compounds, 24 compounds previously reported as pungent compounds and 50 volatile compounds from ginger. The volatile compounds were mainly alpha-zingiberene (22.29%), beta-sesquiphellandrene (8.58%), alpha-farnesene (3.93%), beta-bisabolene (3.87%), alpha-curcumene (2.63%), which were mostly consisted of sesquiterpene hydrocarbons. The pungent compounds of ginger were mainly 6-gingerol (9.38%), 6-shogaol (7.59%), zingerone (9.24%) produced by the thermal degradation of gingerols or shogaols. The mass spectral fragmentation patterns for the three new compounds (6-isogingerol, (Z)-10-isoshogaol, (E)-10-isoshogaol) are discussed and interpreted.
采用超临界流体萃取技术从莱芜大姜中提取姜油树脂。运用气相色谱和质谱技术对姜油树脂进行分析。该分析检测出3种迄今未知的天然化合物、24种先前报道的辛辣化合物以及50种来自生姜的挥发性化合物。挥发性化合物主要为α-姜烯（22.29%）、β-倍半水芹烯（8.58%）、α-法呢烯（3.93%）、β-红没药烯（3.87%）、α-姜黄烯（2.63%），它们大多由倍半萜烃类组成。生姜的辛辣化合物主要是由姜醇或姜辣素热降解产生的6-姜醇（9.38%）、6-姜烯酚（7.59%）、姜酮（9.24%）。对三种新化合物（6-异姜醇、（Z）-10-异姜烯酚、（E）-10-异姜烯酚）的质谱裂解模式进行了讨论和解释。
