Abstract:To analysis the chemical constituents of absolute oil from two varieties of Tuberose in Yunnan provice by GC-MS. Comparing the difference of the chemical constituents between unipetalous Tuberose and polyphyll Tuberose, combineing the sensory evaluation.The dates show that the main compounds include: 3-Cyclohexene-1-methanol, trimethyl-, Benzoic acid, 2-amino-, methyl ester, Benzene, 1,2-dimethoxy-4-(1-propenyl)-, 2,6,10-Dodecatrien-1-ol, 3,7,11-trimethyl-, (E,E)-, BenzylBenzoate, Benzoic acid, 2-hydroxy-, phenylmethyl ester,ect. The contents of main constituents of absolute oil of unipetalous Tuberose are higher than the contents of main constituents of absolute oil of polyphyll Tuberos.For example: the contnets of 3-Cyclohexene-1-methanol, trimethyl-, Benzoic acid, 2-amino-, methyl ester, 2,6,10-Dodecatrien-1-ol, 3,7,11-trimethyl-, (E,E)-, BenzylBenzoate of unipetalous Tuberose are 3.679%, 11.564%, 13.263%, 39.785%; in the contrast polyphyll Tuberose are 2.706%, 6.038%, 6.394%, 26.005%. The extraction rate of polyphyll Tuberose is higher than unipetalous Tuberose.
