Aroma Profiling of Leaf, Flower, Peel and In Vitro Embryo Tissues of “Ciaculli Late” Mandarin

subject

description

Abstract Volatile compounds released from leaf, flower and peel as well as from somatic (nucellar) embryo tissues of “Tardivo di Ciaculli” or “Ciaculli late” mandarin have been collected/ concentrated by headspace solid phase microextraction, HS-SPME, and analyzed by GC-MS. The tehnique allowed the rapid comparison of the volatiles from the various sources; in particular, 19 compounds were identified for the embryos, 16 for leaf and flower and 13 for peel. Limonene was the most abundant volatile component of the embryo and peel while γ-terpinene was the major compound among volatiles from leaf and flower. Relatively high amounts of methyl N-methyl anthranilate and β-caryophyllene were also found, with the excerption of peel, in all the samples. Myrcene was higher than methyl N-methyl anthranilate and β-caryophyllene in flower volatiles.
