Recently, Masson et al. applied the chemical “fingerprinting” techniques of metabolomics to the identification and quality assessment of iris rhizomes. The study involved 22 commercial samples of iris rhizomes, including Iris germanica, I. albicans and I. pallida from Morocco; and I. pallida from both China and Italy.
Compared to the “conventional analysis methods of LC-UV and LC-MS, techniques including exact mass/retention time (EMRT), UHPLC–TOF/HRMS, principal component analysis (PCA), partial least square discriminant analysis (PLS-DA), and then orthogonal partial least square-discriminant analysis (OPLS-DA), performed well.”
Narula et al. recently published a patent application for 3-methyl-cyclohexadec-6-enone, an odorant featuring “a strong musky odor with an unexpected powdery character.” The material can also contribute smooth, creamy, feminine, warm and “comfortable” facets to top and middle notes in fragrance compositions, according to the authors.
