【Abstract】 The chemical constituents of the essential oil from Rhododendron flavidum Franch were not reported before. The essential oil was extracted by steam distillation. After dehydration, the total essential oil was analyzed by capillary gas chromatography and determined by two kinds of fused silica capillary columns of OV 101 and OV 17. The chemical constituents of the essential oil were identified by means of the retention index of capillary gas chromatogryaphy, authentic sample addition process and the GC MS DS. The quantity was fixed by chromatograph LCI 100 with area normalization method. 18 monoterpenes and 41 sesquiterpenes were identified and their relative contents were determined. The main constituents were: β pinene (24 122%), α pinene (18 386%), borynyl acetate (12 652%), limonene (8.225%), β elemene (3.081%), sabinene (2.865%), citronellol (2.426%), myrcene (2.325%), γ terpinene (1.625%), acoradiene(1.623%), p cymene(1.366%) and terpineol 4(1.265%).更多还原
