A 46-year-old female patient presented to our hospital with history of pharyngeal discomfort for 6 months. Physical examination showed that she had facial asymmetry, loss of the left nasolabial fold, rightward de- viation of uvula, swelling of the left soft palate. Magnetic resonance imaging revealed a bigger neoplasm in left pa- rapharyngeal space which invaded into left lateral skull base. The left internal carotid artery, vein and the styloid process was jostled backward. The primary clinical diagnosis is pleomorphic adenoma of the parapharyngeal space.

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.
