Abstract:The essence of Rosa chinensis, flower were trapped by a modified circulating adsorption method with XAD-4 as adsorbent and were analyzed by GC and GC/MS techniques. The components were identified by mass spectral and temperature-programmed retention index data on dual glass capillary columns. The major constituents are linalool acetate (14.98%), limonene (12.07%), benzene methyl methoxy (9.88%), citronellol (4.82%), beta-caryophyllene (4.55%), hexanol acetate (3.98%), linalool (3.18%), hexanol (3.17%) etc.
