The volatile components of garlic were studied by GC-MS. The components in the cyclohexane, Et acetate and n-butanol extracts of the 95% alc. extract of garlic (Allium sativum) were compared with the volatile oil obtained by steam distillation from garlic. Qual. and quant. analyses were carried out by GC-MS (gas chromatog.-mass spectrometry). From the cyclohexane extraction, 112 components were detected and 38 compounds were identified, accounting for 80.08% of the cyclohexane extraction From the Et acetate extraction, 86 components were detected and 26 compounds were identified, accounting for 56.70% of the Et acetate extraction From the n-butanol extraction, no volatile component was detected by GC-MS. From the volatile oil obtained by steam distillation, 109 components were detected and 29 compounds were identified, accounting for 83.58% of the total volatile oil. The cyclohexane extraction and the Et acetate extraction of the 95% ethanol extract of garlic and the volatile oil were dominated by organosulfur components. According to the analyses of the cyclohexane extraction and the Et acetate extraction of the 95% ethanol extract of garlic, the contents of ajoene in the crude drug were 0.00395% and 0.00145%, resp. The content of ajoene in garlic was 0.00540%. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9Synthetic Route of C9H16O4).
Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C9H16O4
