Volatile Profiles of Five Variants of Abeliophyllum distichum Flowers Using Headspace Solid-Phase Microextraction Gas Chromatography–Mass Spectrometry (HS-SPME-GC-MS) Analysis

Abstract

Abeliophyllum distichum (Oleaceae), which is the only species in the monotypic genus and is grown only on the Korean peninsula, has a high scarcity value. Its five variants (white, pink, round, blue, and ivory) have different morphological characteristics in terms of the color of petals and sepals or shape of the fruits. Despite its high value, there has been no study on variant classification except in terms of their morphological characteristics. Thus, we performed a volatile component analysis of A. distichum flowers and multivariate data analyses to reveal the relationship between fragments emitted from five variants of A. distichum flowers with their morphological characteristics. As a result, 66 volatile components of this plant were identified by headspace solid-phase microextraction gas chromatography–mass spectrometry (HS-SPME-GC-MS), showing unique patterns for each set of morphological characteristics, especially the color of the petals. These results suggest that morphological characteristics of each variant are related to the volatile composition.

Comprehensive Evaluation of the Volatomic Fingerprint of Saffron from Campania towards Its Authenticity and Quality

“…These oxygenated monoterpenoids are from the most complicated chiral floral scent compounds and have been identified among the main volatile components in many plants, most of all ornamental species, harvested all over the world, as important metabolites for the attraction of pollinators. In addition, these VOCs have been also described as key volatile markers in several honeys [22][23][24]. To the authors knowledge, lilac aldehyde and lilac alcohol isomers have never been detected in the VOCs profile of saffron.…”

Latest Improvements and Expanding Applications of Solid-Phase Microextraction

“…A large number of plants own distinctive odors. Analyzing these odors is expected to reveal unique biomarkers for species identification and provide important data for economic valuation. − HS-SPME is an excellent candidate for odor enrichment, and the mixed fibers including DVB/CAR/PDMS, CAR/PDMS, and PDMS/DVB are preferred due to the synergetic effects of absorbents and adsorbents. − It is worth mentioning that the hybrid composites of silica aerogel, preyssler-type polyoxometalate, and MIL-101­(Cr) have been fabricated as a highly porous fiber coating, which has been successfully used for the headspace extraction and identification of Ferulago angulata volatile components. Exerting a magnetic field on the prepared SPME fiber using a permanent magnet substantially improves the extraction efficiency for the volatile components, to an average of 73% …”

Gas Chromatography-Mass Spectrometry Metabolites and Transcriptome Profiling Reveal Molecular Mechanisms and Differences in Terpene Biosynthesis in Two Torrya grandis Cultivars during Postharvest Ripening

“…The aroma also has a strong influence on fruit quality, with volatile components being the decisive factor between species [ 9 , 10 ]. At present, headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography–mass spectrometry (GC-MS) is a widely used and efficient method for aroma detection and analysis [ 11 , 12 , 13 , 14 , 15 , 16 ]. Aroma means ‘Xiang’ and T. grandis means ‘Xiang Fei’ in Chinese.…”
