Volatile emission of different plant parts and fruit development from Italian cherry plums (Prunus cerasifera and P. cerasifera Pissardii)

The chemical composition of volatiles emitted in vivo from different plant parts of P. cerasifera and P. cerasifera â Pissardiiâ 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 90.1â 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.
