Title: Extraction and GC-MS Analysis of Essential Oil from Flower of Paniculate Goldraintree
Abstract: OBJECTIVE To analyze the compositions of essential oil from flower of paniculate goldraintree.METHODS To isolate by steam distillation and analyze by GC-MS.Relative content of each component was determined by area normalization.Immersion them 20 hours and heating them to 8 hours until the essential oil did not increase.GS-MS conditions: DB-5MS capillary column(0.2 mm×30 m,0.25 μm),carrier gas was high purity helium,flow rate was 1 mL·min-1.MS conditions: EI ionization 70 eV,ion source temperature was 200 ℃.RESULTS Thirty-five compounds,representing 98.8% of total oil,were indentified and their relative amount was determined.CONCLUSION The oil is rich in 3-methyl-4-oxopentanoic acid(49.71%),n-hexadecanoic acid(16.16%),myristic acid(2.62%),linolenic acid(2.38%),(Z,Z)-9,12-octadecadienoic acid(2.36%),2-pentadecanone(2.32%),hexatriacontane(2.17%),benzeneacetaldehyde(2.05%).
