摘要
利用色彩分析仪测定焦栀子碎炒和个炒炒制过程样品的色度值,并利用超高效液相色谱法(UPLC)测定10个主要成分含量,对颜色与成分含量进行多元统计分析、皮尔逊相关分析与判别分析。实验结果显示,炮制过程中,L*,a*,b*和E*ab均不断下降,颜色逐渐加深,碎炒和个炒在炮制过程中色度值参数变化趋势和范围基本一致;羟异栀子苷、西红花苷-Ⅰ(crocin-Ⅰ,C-Ⅰ)和西红花苷-Ⅱ(crocin-Ⅱ,C-Ⅱ)含量明显下降,栀子苷酸和5-羟甲基糠醛(5-hydroxymethylfurfural, 5-HMF)含量呈明显上升;山栀苷、去乙酰车叶草苷酸甲酯和京尼平苷(geniposide, G2)含量整体上呈下降趋势,鸡屎藤次苷甲酯呈先上升后下降的趋势,京尼平-1-O-龙胆二糖苷(genipin-1-O-gentiobioside, G1)呈下降、上升、再下降的趋势;碎炒和个炒在炮制过程中成分含量的变化趋势基本一致,但变化幅度存在差异,其中鸡屎藤次苷甲酯和G1较为明显,且由于炒制时间不同,碎炒工艺下各成分含量变化速率高于个炒;栀子苷酸、羟异栀子苷、鸡屎藤次苷甲酯、C-Ⅰ、C-Ⅱ、5-HMF与表观颜色相关性较高;建立2种炒制工艺的判别函数,能够适用于碎炒和个炒的判别。该研究基于颜色-成分关联分析揭示2种炮制过程的质量动态变化规律,2种炮制过程质量变化趋势基本一致,但由于饮片炒制形态不同,质量传递略有差异,为焦栀子的炮制工艺提供数据支撑。
The chromatic values of the broken-fried and single-fried Gardeniae Fructus Praeparatus(GFP) were measured by the color analyzer to analyze the color variation rule, and the contents of 10 main components were determined by ultra-high performance liquid chromatography(UPLC). The multivariate statistical analysis, Pearson correlation analysis, and discriminant analysis were conducted to investigate the color and components of GFP samples. The experimental results revealed that L*, a*, b*, and E*ab decreased continuously during processing, and the color of samples gradually deepened. The trend and range of chromatic values during broken-frying and single-frying processes were basically identical. Gardenoside, crocin-Ⅰ(C-Ⅰ), and crocin-Ⅱ(C-Ⅱ) showed an obviously downward trend, while the contents of geniposidic acid and 5-hydroxymethylfurfural(5-HMF) increased significantly. Shanzhiside, deacetyl-asperulosidic acid methyl ester, and geniposide(G2) showed a downward trend. Scandoside methyl ester rose first and fell later. Genipin-1-O-gentiobioside(G1) went through a decrease-increase-decrease trend. The change trends of component contents during broken-frying and single-frying processes were generally consistent, but the change range was different. Among all the components, scandoside methyl ester and G1 showed obvious change. Because of different stir-frying time, the change rate of each component content in the process of broken-frying was higher than that in single-frying process. Additionally, geniposidic acid, gardenoside, scandoside methyl ester, C-Ⅰ, C-Ⅱ, and 5-HMF exhibited a higher correlation with apparent color. On the basis of above findings, the discriminant function of two frying processes was established, which could be applied to the discrimination of broken-fried and single-fried samples. This study analyzed the dynamic quality change rule of GFP during broken-frying and single-frying processes based on color-component correlation analysis, and found the two methods showed consistent change trend, yet with slight difference in the quality of samples. This study can provide data support for the processing of GFP.
