Ssajuari-ssuk and sajabal-ssuk have many clinical benefits. It is difficult to discriminate between these two species based on general characteristics aside from the shapes of the leaves. Thus, species identification and quality control between ssajuari-ssuk and sajabal-ssuk are of great concern in plant science and clinical therapy.
The aim of this study is to determine whether fast gas chromatography with uncoated surface acoustic wave sensor (GC-SAW) can be a useful technique for performing species identification and quality control using volatile patterns of ssajuari-ssuk and sajabal-ssuk air-dried for 4 months and 2 years and 4 months.
Fast GC-SAW sensor provides second unit analysis, simple, on-line measurements that do not require pretreatment of the sample and rapid sensory information. Headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) was employed to confirm the identification of the volatiles and compared to fast GC-SAW sensor.
In air-dried sajabal-ssuk, the concentration of 1,8-cineole was higher than that in air-dried ssajuari-ssuk, while the level of α-thujone was considerably lower than that of air-dried ssajuari-ssuk. Each of ssajuari-ssuk and sajabal-ssuk air-dried for 4 months and 2 years and 4 months has its own characteristic volatile pattern owing to its individual chemotypes or chemical compositions.
Consequently, the fast GC-SAW sensor can be a useful technique for species identification and quality control using volatile patterns of ssajuari-ssuk and sajabal-ssuk air-dried for 4 months and 2 years and 4 months. This method can be used for the standardisation of quality control using volatile patterns of herbal medicines.
沙枣儿-苏克和沙棘-苏克具有多种临床益处。除了叶子形状外，很难根据一般特征区分这两个物种。因此，沙枣儿-苏克和沙棘-苏克之间的物种鉴定和质量控制在植物科学和临床治疗中备受关注。
本研究的目的是确定使用未涂覆表面声波传感器的快速气相色谱法（GC-SAW）是否可以作为一种有用的技术，通过对风干4个月、2年零4个月的沙枣儿-苏克和沙棘-苏克的挥发性成分模式进行物种鉴定和质量控制。
快速GC-SAW传感器提供二次单元分析、简单的在线测量，无需对样品进行预处理，并能快速提供传感信息。采用顶空固相微萃取气相色谱-质谱联用（HS-SPME-GC-MS）来确认挥发性成分的鉴定，并与快速GC-SAW传感器进行比较。
在风干的沙棘-苏克中，1,8-桉叶素的浓度高于风干的沙枣儿-苏克，而α-侧柏酮的含量则明显低于风干的沙枣儿-苏克。由于其各自的化学型或化学成分，风干4个月、2年零4个月的沙枣儿-苏克和沙棘-苏克都有其独特的挥发性成分模式。
因此，快速GC-SAW传感器可以作为一种有用的技术，通过对风干4个月、2年零4个月的沙枣儿-苏克和沙棘-苏克的挥发性成分模式进行物种鉴定和质量控制。该方法可用于利用草药挥发性成分模式进行质量控制的标准化。
