Study of the Volatile Components of the Fruit of Ziziphus mauritiana Lam. by GC-MS

The volatile components in the fruit of Ziziphus mauritiana Lam. were analyzed quantitatively by simultaneous distillation and extraction equipment(SDE) and gas chromatography-mass spectrometry(GC-MS).40 volatile components were identified and determined,amounting to 79.07% of the total area of the peaks.The principal constituents in the volatiles were bis(2-ethylhexyl) phthalate(18.00%),dibutyl phthalate(12.33%),5-hexyldihydro-2(3H)-furanone,(4.60%),dodec-2-en-4-one(2.75%),2-tridecanone(2.25%),tetradecane(2.15%),eicosane(1.44%),2-tetradecanone(2.14%),(E)-2-decenal(2.07%),2-nonen-4-one(2.00%),hexanoic acid hexyl ester(1.93%),nonanal(1.87%),propyl-propanedioic acid(1.73%),5-methyl-2-furancarboxaldehyde(1.70%),nonacosane(1.52%),ethyl tridecanoate(1.52%),hexanoic acid ethyl ester(1.46%),6-methyl-2-tridecanone(1.30%),tetradecanoic acid ethyl ester(1.09%),4-hydroxy-6-methyl(2H)-pyran-2-one(1.09%),and butylated hydroxytoluene(1.02%).
