Jin, Jing published the artcileDetermination of Volatiles in Rosa Rugosa by Knitting Aromatic Polymer – Polydopamine (KAP@PDA) Solid-Phase Microextraction (SPME) and Multidimensional Gas Chromatography – Mass Spectrometry (MDGC-MS), Recommanded Product: Methyl octanoate, the main research area is Rosa phenylethyl alcoho volatile compound polydopamine.
The volatile compounds in Rosa rugosa ‘Zi Zhi’, R. rugosa ‘Feng Hua’, and R. cv ‘Crimson Glory’ from three regions were determined by two-dimensional gas chromatog. with quadrupole time-of-flight mass spectrometry coupled with knitting aromatic polymer – polydopamine (KAP@PDA) solid-phase microextraction 82 compounds were identified by peak matching and retention indexes, and R. cv ‘Crimson Glory’ contained the most volatile components. D-Limonene (up to 5131μg kg-1), benzyl alc. (up to 16,510μg kg-1), benzeneacetaldehyde (up to 13,820μg kg-1), phenylethyl alc. (up to 49,020μg kg-1) and citronellol (up to 7129μg kg-1) were the major constituents in all R. rugosa species. In addition, benzaldehyde was highly abundant in R. cv ‘Crimson Glory’ (up to 23,130μg kg-1). The primary volatile components responsible for the differences among the three R. rugosa cultivars and regions were distinguished by orthogonal partial least-squares discriminant anal. The results suggested that phenylethyl alc. contributed the most in distinguishing aroma quality for R. rugosa cultivars and those from different regions.
