Volatile components of Rhizoma Alpiniae Officinarum using three different extraction methods combined with gas chromatography-mass spectrometry

摘要

Volatile components from Rhizoma Alpiniae Officinarum were respectively extracted by three methods including hydrodistillation,headspace solid-phase microextraction(HS-SPME) and diethyl ether extraction.A total of 40(hydrodistillation),32(HS-SPME) and 37(diethyl ether extraction) compounds were respectively identified by gas chromatography-mass spectrometry(GC/MS) and 22 compounds were overlapped,including a-farnesene,g-muurolene,2,6-dimethyl-6(4-methyl-3-pentenyl)bicyclo[3.1.1]hept-2-ene,eucalyptol and cadina-1(10),4-diene and so forth,varying in relative contents.HS-SPME is fast,sample saving and solvent-free and it also can achieve similar profiles as those from hydrodistillation and solvent extraction.Therefore,it can be the priority for extracting volatile components from medicinal plants.
