To conduct comparative study on the volatile components from Polygonati Rhizoma during processing.
Volatile 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.
The 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.
This study is useful to illustrate the mechanism of decreasing toxicity and stimulating components after being processed.
对黄精炮制前后的挥发性成分进行对比研究。
采用水蒸气蒸馏法（SD）从黄精中提取挥发油。通过吹扫捕集-热脱附（P&T-TD）法浓缩挥发性成分，并用气相色谱-质谱联用仪（GC-MS）进行分析，同时与SD-GC-MS法进行对比分析。
观察到黄精炮制前后挥发性成分在数量和质量上的变化。SD-GC-MS法检出51种化合物，而P&T-TD-GC-MS法检出11种化合物。
本研究有助于阐明黄精炮制后减毒及刺激性成分降低的机制。
