Abstract:In this study, the essential oils of the Rosa acicularis ‘Luhe’and Lindl were measured and their oil yield, the volatile components and fatty acid composition were compared. The results showed that the oil yield of ‘Luhe’ was significantly higher than that of Lindl (p<0.05). With gas chromatography-mass spectrometry (GC-MS), we have separated and identified the volatile components of two kinds of Rosa acicularis. After analysis, it was clear that the ‘Luhe’ contains 70 kinds of known ingredients and Lindl contains 68 components. The main volatile components were eicosane, pentadecane, triacontane and dibutyl phthalate. There was no significant difference in volatile components content among Rosa acicularis species(p>0.05).The composition and content of fatty acids were determined by gas chromatography (GC), and 29 fatty acids were detected in both ‘Luhe’ and Lindl. Among them, decanoic acid, palm oleic acid, trans oleic acid, and twenty carbonic acid were abundant. Compared to traditional Rosa acicularis Lindl, the Rosa acicularis ‘Luhe’, as an improved variety, retains the original characteristics of wild species (Rosa acicularis Lindl).
