The volatiles of different pomegranate plant parts were extracted using headspace solid phase micro-extraction (HS-SPME) and analyzed for the first time by gas chromatography-mass spectrometry (GC–MS) and flame ionization detector (GC-FID). All the data were submitted to multivariate statistical analysis evidencing many differences amongst the selected plant parts. Sesquiterpene hydrocarbons were the most abundant class in the aroma of leaves and in all the flower organs where the main constituents were β-caryophyllene, ( E , E )-α-farnesene and trans -α-bergamotene. Stem aroma showed similar content of sesquiterpene hydrocarbons and non-terpenes with α-humulene as main compound. The aroma of all aril parts showed high amount of non-terpenes with the prevalence of aldehydes and esters. [ABSTRACT FROM AUTHOR]

The chemical composition of volatiles emitted in vivo from different plant parts of P. cerasifera and P. cerasifera ‘Pissardii’ were collected during the entire biological cycle of the plant growth and analyzed by gas chromatography mass spectrometry (GC-MS) after solid phase micro-extraction (SPME). All the data were submitted to multivariate statistical analysis evidencing many differences amongst the selected plant parts and growth stages. A total of 136 compounds were identified corresponding to 90.1–99.6% of the whole aroma profile of cherry plum samples. Non-terpenes were the most abundant class of constituents present in the volatile emission of all analyzed samples. In particular, the aroma of both fruit stages was mainly characterized by alcohols and esters in different amounts. [ABSTRACT FROM AUTHOR]
