A novel analytical method using fast gas chromatography combined with surface acoustic wave sensor (GC/SAW) has been developed for the detection of volatile aroma compounds emanated from lilac blossom (Syringa species: Syringa vulgaris variginata and Syringa dilatata). GC/SAW could detect and quantify various fragrance emitted from lilac blossom, enabling to provide fragrance pattern analysis results. The fragrance pattern analysis could easily characterize the delicate differences in aromas caused by the substantial difference of chemical composition according to different color and shape of petals. Moreover, the method validation of GC/SAW was performed for the purpose of volatile floral actual aroma analysis, achieving a high reproducibility and excellent sensitivity. From the validation results, GC/SAW could serve as an alternative analytical technique for the analysis of volatile floral actual aroma of lilac. In addition, headspace solid-phase microextraction (HS-SPME) GC-MS was employed to further confirm the identification of fragrances emitted from lilac blossom and compared to GC/SAW.
一种结合快速气相色谱与表面声波传感器的新型分析方法（GC/SAW）已被开发出来，用于检测丁香花（丁香属植物：紫丁香变种和暴马丁香）散发的挥发性香气化合物。GC/SAW能够检测并定量丁香花散发的各种香气，从而提供香气模式分析结果。香气模式分析能够轻松地根据花瓣颜色和形状的显著差异所导致的化学成分的巨大差异，来表征香气中的细微差别。此外，为了进行挥发性花香实际香气分析，对GC/SAW进行了方法验证，实现了高重现性和出色的灵敏度。从验证结果来看，GC/SAW可作为分析丁香挥发性花香实际香气的替代分析技术。此外，还采用顶空固相微萃取（HS-SPME）气相色谱-质谱联用技术进一步确认丁香花散发香气的鉴定结果，并与GC/SAW进行比较。
