Propylene oxide, a favorite target of experimental and theoretical studies of circular dichroism, was recently discovered in interstellar space, further amplifying the attention to its role in the current debate on protobiological homochirality.
A variety of extraction methodologies were applied to chinotto (Citrus myrtifolia) fruits from Sicily, along with sensory and chemical analyses. By gas chromatographic techniques, either in monodimensional (GC-FID, GC–MS) or in multidimensional (MDGC) fashion, it was established how the isolation procedure affected the volatile fingerprint of such fruit. In general, limonene, linalyl acetate, myrcene, β-pinene, α-pinene, (E)-β-ocimene, linalool and geranyl acetate resulted to be the predominant volatiles.
