Abstract:
OBJECTIVETo conduct comparative study on the volatile components from Polygonati Rhizoma during processing.
METHODVolatile oil was obtained from Polygonati Rhizoma by steam distillation (SD). Volatile components were concentrated by a purge and trap-thermal desorption (P&T-TD) method, and analyzed with gas chromatography-mass spectrometry (GC-MS), which were comparative by analyzed with the method of SD-GC-MS simultaneously.
RESULTThe change in quantity and quality of volatile components in pre and post processed Polygonati Rhizoma were observed. Fifty-one compounds were checked out with SD-GC-MS, while 11 compounds with P&T-TD-GC-MS.
CONCLUSIONThis study is useful to illustrate the mechanism of decreasing toxicity and stimulating components after being processed.
