Abstract

Abstract: Solidago is a genus of more than 120 species of flowering plants in the Asteraceae family and mainly distributed in Americas. To explore the differences of volatile components and analyze their correlations as well variability among the five species ( Solidago caesia, Solidago tortifolia, Solidago glomerata, Solidago nemoralis and Solidago rugosa ) of this genus, their volatile components were determined by gas chromatography-mass spectrometry (GC-MS) and then the principal component analysis (PCA) was carried out with PAST (PAST2.08). The results indicated that Solidago caesia almost characterized by the same chemotype with Solidago glomerata due to their common essential oil compositions b-cubebene, (1R)-(+)-α-pinene and (−)-a-cadinol while Solidago nemoralis has little variability with Solidago rugosa and with the presence of germacrene D, limonene and sabenene as the representative compounds. But there is chemical variability between Solidago tortifolia and other four species. Sabenene and πcalacorene are the major volatile compounds of Solidago tortifolia . Highlights: We extract the essential oils from five species of genus Solidago using steam distillation method. The composition of essential oils from five species plants of genus Solidago were determined by GC-MS for the first time. The variability of five species of genus Solidago were analyzed, it will be meaningful in phytochemical toxonomy.
