摘要
采用裂解色谱法测定,运用模糊聚类法分析比较不同品种荔枝的指纹图谱。研究结果表明,裂解温度、裂解时间分别选择450℃、30 s较为合适,21种荔枝样品的指纹图谱具有相似性,重现性好。该方法具有快速、简便、准确等特点,可为进一步开展荔枝的品质鉴定提供依据。
The fingerprints of Litchi from different cultivars were studied and compared by pyrolysis-gas chromatography with fuzzy cluster analysis,and the effects of pyrolysis temperature and pyrolysis time on the fingerprint had been studied in this paper.Pyrolysis temperature and pyrolysis time played important roles in the experiments,and 450℃ and 20 s were selected as the optimized conditions.The method had a good reproducibility.The pyrolysis-gas chromatography was simple,rapid,accurate and scientific determination method for the identify of quality of Litchi.
