Note: Components are listed in order of elution, and nomenclature is in accordance with NIST (National Institute of Standards and Technology). LRI (Calculated): The calculated linear retention index was obtained by comparison to an alkane C₇–C₂₀ standard mixture analyzed in the same conditions as the samples on a non-polar column. LRI (Literature): linear retention index in literature. CAS #: registry number assigned by the Chemical Abstracts Service. S.D.: standard deviation.
