abstract = "A comparative gas chromatography-olfactometry (GC-O) analysis of the volatiles isolated from tree-ripened fruits of cempedak (Artocarpus integer (Thunb.) Merr.) and jackfruit (Artocarpus heterophyllus Lam.) afforded 33 aroma-active compounds. Two of them were detected in the cempedak fruit sample, but not in the jackfruit sample and exhibited an odor corresponding to the characteristic sulfury, smear cheese-like note distinguishing cempedak fruit aroma from jackfruit aroma. These compounds were identified as 2-(methylthio)-butane and 2-(methylthio)pentane. Both compounds have rarely been reported from nature and were as yet unknown in any fruit. Enantio-GC analysis revealed an (R)/(S) ratio of 33/67 for 2-(methylthio)butane and 41/59 for 2-(methylthio)pentane in cempedak fruit. The odor qualities of the enantiomers were virtually identical, but slight differences were found in the odor threshold values.",
