藏红花的质量取决于次级代谢产物的浓度，如藏红花素，苦藏红花素和番红花醛。本研究的目的是评估干燥条件对意大利中部Cascia地区生产的西洋参中次生代谢产物含量的影响。将相同的藏红花样品的不同等分试样置于各种脱水条件下，并通过紫外可见分光光度法进行分析，以测定藏红花素、苦藏红花素和番红花醛。采用高分辨气相色谱法分析了番红花醛，采用高效液相色谱-二极管阵列质谱检测器分析了藏红花素和苦藏红花素，结果表明，在较温和条件下干燥的样品中次生代谢物含量最低。此外，在60 ° C下干燥55分钟的样品呈现出最高的反式藏红花素-4和苦藏红花素含量，而在55 ° C下干燥95分钟的藏红花中最具代表性的是番红花醛（C）2013 Elsevier Ltd.保留所有权利。
Saffron's quality depends on the concentration of secondary metabolites, such as crocins, picrocrocin and safranal. The aim of this research was to evaluate the influence of drying conditions on the secondary metabolite contents of saffron produced in the area of Cascia, in central Italy. Different aliquots of the same saffron sample were subjected to various dehydration conditions and analysed by UV-Vis spectrophotometry to determine crocins, picrocrocin and safranal.. Safranal was also analysed by high resolution gas chromatography, while the crocins and picrocrocin were determined by high-performance liquid chromatography with diode array and mass spectrometric detectors.The results of chromatographic analyses showed that the samples dried in the milder conditions had the lowest content of secondary metabolites. Moreover the sample dried at 60 degrees C for 55 min presented the highest contents of trans-crocin-4 and picrocrocin, while safranal was most represented in saffron dried at 55 degrees C for 95 min.
