Abstract

|
|
|
Pyroligneous liquor as a byproduct from charcoal production of bamboo sprout produced damyang-gun has the broad benefits such as improvement of soil quality, plant growth control and is mainly used for the treatment of atopic dermatitis, fungi and many other skin diseases. In this study, flavor compounds of pyroligneous liquor from bamboo sprout produced in Damyang-gun were analyzed and compared using three different methods including direct analysis (DA), headspace solid phase microextraction (HS-SPME) and stir bar sorptive extraction (SBSE). Simultaneously, the analytical conditions of GC-MS for the determination of volatile compounds were optimized. Based on volatile organic compounds detected by GC-MS, SBSE and SPME methods showed higher sensitivity than direct analysis. Major compounds of pyroligneous liquor were cresol, guaiacol, p-ethyl guaiacol and syringol. These phenolic compounds are reported as the useful chemicals with medicinal activity.
