Headspace nanofiber sheet microextraction together with GC – MS and chemometrics resolution techniques were implemented to separate and identify the volatiles emitted by intact marjoram ( Origanum majorana L .) and their relative concentrations. A novel polyaniline‐nylon‐6 nanofiber composite was applied for headspace microextraction. Characteristics such as high surface‐to‐volume ratio and π–π functional groups in polyaniline together with the NH and C = O functional groups in nylon‐6 make the polyaniline‐nylon‐6 nanofiber composite a suitable candidate for the extraction of volatiles and semivolatiles. The extracted constituents were desorbed and injected into the GC – MS system under the optimum conditions. Chemometric resolution techniques were utilized to solve the baseline offset, asymmetric peaks, and overlapped peaks problems that arise from GC – MS analysis. By means of these techniques and resolving the overlapped peak clusters, the number of identified constituents was increased to 67 compounds. The major released constituents from the intact marjoram leaves are 4‐terpineol, β‐linalool, cis ‐sabinol, and trans ‐geraniol.
