夜寒苏(圆瓣姜花)的鉴定及挥发油成分GC-MS分析

Identification of Rhizoma hedychii (Hedychiam forrestii)and GC-MS Analysis of Volatile Oil Components

目的:为夜寒苏(Rhizoma hedychii)的研究和利用提供新的参考资料和依据。方法:应用中药鉴定学方法对夜寒苏姜科姜花属植物圆瓣姜花Hedychium forrestii Diels.的干燥根茎进行原植物鉴别、性状鉴别、显微鉴别以及气相色谱-质谱联用分析其挥发油成分。结果:其根状茎维管束呈外韧型,散生,皮层和中柱有油细胞存在,薄壁细胞内有淀粉粒和草酸钙方晶;主要挥发油成分为β-蒎烯、α-蒎烯、桉油精、α-萜品醇、4-松油醇等。结论:姜科姜花属植物圆瓣姜花为夜寒苏一个新的植物来源。

OBJECTIVE： To provide new reference material and basis for the study and utilization of Rhizoma hedychii. METHODS： Pharmacognosy was used for the identification of original plant, characteristics identification and microscopic identification of Rhizoma hedychii, which was the rhizome of Hedychium genus of the Zingiberaceae： Hedychium forrestii. GC-MS was used for analysis of volatile oil. RESULTS ： The vascular bundles were collateral type and scattered, its stele and cortex had oil cells, and thin-walled cells contained starch grains and calcium oxalate crystals. The main volatile oil components were β-pinene, α-pinene, eucalyptol and α-terpineol, 4-terpineol, etc. CONCLUSION ： Hedychium genus of the Zingiberaceae ： H. forrestii is a new plant origin of Rhizoma hedychii.
