摘 要 目的 探究酸枣仁炒制过程中成分含量与色度的相关性,为酸枣仁炒制程度提供判别指标。方法 采用清炒法制备不同
炒制时间点的样品,以超高效液相色谱法定量分析酸枣仁生品与不同炒制时间点样品中8种主要成分(腺苷、木兰花碱、酸枣仁皂
苷A、斯皮诺素、6″ ′ -阿魏酰斯皮诺素、白桦脂酸、油酸、亚油酸),以紫外分光测色仪测定其色度值,应用Pearson相关性分析、线性
回归分析、主成分分析(PCA)、聚类热图分析(CHA)、偏最小二乘判别分析(PLS-DA)等多种分析方法分析不同炒制时间点的酸枣
仁色度值与其成分含量之间的相关性及差异,以明确其炮制终点。结果 随炒制时间延长,亚油酸、油酸含量降低,其余成分含量
升高;色度值L*和E*ab下降,a*缓慢上升。Pearson相关性分析显示,L*、E*ab与腺苷、斯皮诺素、6″ ′ -阿魏酰斯皮诺素、酸枣仁皂苷
A、白桦脂酸和木兰花碱含量均呈显著负相关(P<0.05)。线性回归分析结果表明,可通过分析酸枣仁粉末色度值,初步预测该药
材中腺苷等6种成分的含量。PCA和CHA可区分生品与炒制品。PLS-DA结果表明,L*、E*ab、a*、亚油酸含量、油酸含量是影响
不同炒制时间点酸枣仁颜色与质量的主要差异性参数。炒制9~10 min时,L*和E*ab降至最低且稳定,a*较高且变化平缓;同时,
除亚油酸、油酸外的6种成分含量均达到峰值。结论 酸枣仁的色度值与腺苷等6种成分含量呈现出显著的相关性,其最佳炒制时
间范围为9~10 min。所建立的色度-成分含量关联分析方法切实可行,可用于酸枣仁炒制程度的判别。

ABSTRACT OBJECTIVE To investigate the correlation of component content with colorimetric values during the roasting
process of Ziziphus jujuba, and to provide criteria for discriminating the roasting degree of Z. jujuba. METHODS Samples were
prepared by dry stir-frying for different roasting times. The eight main components in raw Z. jujuba and the samples stir-fried for
different roasting times-namely adenosine, magnoflorine, jujuboside A, spinosin, 6 ″ ′ -feruloylspinosin, betulinic acid, oleic acid,
and linoleic acid-were quantitatively analyzed using ultra-performance liquid chromatography. The chromaticity values were
determined using a UV spectrophotometer. The correlation and differences between the chromaticity values of Z. jujuba at different
roasting times and their components content were analyzed by Pearson correlation analysis, linear regression analysis, principal
component analysis (PCA) , cluster heatmap analysis
