Rapid Monitoring of Pharmacological Volatiles of Night‐Flowering Evening‐Primrose According to Flower Opening or Closing by Fast Gas Chromatography/Surface Acoustic Wave Sensor (Electronic zNose)

Abstract

The results showed that flower opening is related to the volatiles emission, which is pharmacological and plant defensive. GC/SAW can be a useful analytical method for the rapid monitoring of volatiles of evening-primrose according to the opening or closing as it provides second unit analysis, as well as simple, and aroma pattern recognition.

A useful quality control using herbal volatiles of Artemisia princeps Pamp. cv. ssajuari (ssajuari‐ssuk; Korean mugwort) according to air‐drying time by fast gas chromatography with uncoated surface acoustic wave sensor (Electronic zNose)

“…Fast GC/SAW sensor, called “Electronic zNose”, is also a headspace sampling method and is an effective simple analytical method with a second unit analysis providing on‐line measurements without the need for pretreatment of the sample. Therefore, fast GC/SAW sensor overcomes the issue of rapid decomposition of plant materials by enzymes and the loss of volatiles 11–16 …”

“…In our earlier study fast GC/SAW sensor was used to discriminate between and perform quality control of medicinal plants according to different petal colours and shapes; sunny day or rainy day sampling; botanical and geographical origins; three different plant parts, including leaves, aerial stems, and underground stems; and open versus closed flowers 11–16 …”

“…Therefore, fast GC/SAW sensor overcomes the issue of rapid decomposition of plant materials by enzymes and the loss of volatiles. [11][12][13][14][15][16] Various SAW sensors use sensitive coating films on the SAW sensor surface. The sensitive film can strongly adsorb certain vapours with great specificity.…”

Rapid Determination and Quality Control of Pharmacological Volatiles of Turmeric (Curcuma longa L.) by Fast Gas Chromatography–Surface Acoustic Wave Sensor

“…At present, GC-SAW has been applied in many areas, including water quality monitoring, environment monitoring, and the detection of flowers and medicinal plants [ 17 , 18 , 19 , 20 ]. However, it has not yet been used for the analysis of pharmacologically volatile compounds in different parts of turmeric, or for different origins of turmeric.…”
