摘要: 考察不同干燥方式对三叶青Tetrastigma hemsleyanum叶片多酚类成分含量的影响,为其加工方法提供科学依据。采用超高液相色谱测定阴干、烘干(40、60、80 ℃)和冻干(–20 ℃)三种干燥方式提取物中新绿原酸、绿原酸、3-O-对香豆酰基奎宁酸、异荭草素、荭草素、异牡荆素、牡荆素含量,并结合熵权-TOPSIS对各干燥方式进行综合分析。结果表明,含量测定方法学验证结果良好,7种多酚类成分(新绿原酸、绿原酸、3-O-对香豆酰基奎宁酸、异荭草素、荭草素、异牡荆素、牡荆素)含量范围分别为0.67~5.39、1.05~8.12、0.22~0.63、0.60~1.38、0.93~1.37、0.38~0.66、0.56~1.21 mg·g–1;多酚类成分总量为4.47~18.15 mg·g1,酚酸类成分(新绿原酸、绿原酸、3-O-对香豆酰基奎宁酸)总量为1.94~14.14 mg·g–1,黄酮类成分(异荭草素、荭草素、异牡荆素、牡荆素)总量为2.53~4.41 mg·g–1。熵权-TOPSIS分析结果显示,80 ℃烘干较适合三叶青叶片干燥。该研究建立的方法准确、稳定、可靠;三种干燥方式对三叶青叶片多酚类成分含量影响显著,80 ℃烘干可能为最佳干燥方式,为后续三叶青叶片趁鲜加工工艺研究提供参考。

Abstract: The effects of different drying methods on the content of polyphenolic components in Tetrastigma hemsleyanum leaves were investigated using ultra-high performance liquid chromatography (UHPLC) to provide an experimental basis for its processing methods. The contents of neo-chlorogenic acid, chlorogenic acid, 3-O-p-coumaroylquinic acid, isoorientin, orientin, isovitexin, and vitexin were determined from the leaves with three drying methods: shade-drying, oven-drying (40, 60, 80 ℃), and freeze-drying (–20 ℃). The drying methods were then comprehensively analyzed using the entropy weight-TOPSIS method. The validation results of content determination methodology were good, and the content ranges of seven ployphenols components (neo-chlorogenic acid, chlorogenic acid, 3-O-p-coumaroylquinic acid, isoorientin, orientin, isovitexin, vitexin) in T. hemsleyanum were 0.67–5.39, 1.05–8.12, 0.22–0.63, 0.60–1.38, 0.93–1.37, 0.38–0.66, 0.56–1.21 mg·g–1, respectively. The total contents of ployphenol, phenolic acids (neo-chlorogenic acid, chlorogenic acid, 3-O-p-coumaroylquinic acid), and flavonoids (isoorientin, orientin, isovitexin, vitexin) ranged from 4.47 to 18.15 mg·g–1, 1.94 to 14.14 mg·g–1, and 2.53 to 4.41 mg·g–1, respectively. Entropy weight-TOPSIS analysis showed that drying at 80 ℃ was suitable for T. hemsleyanum leaf drying. The established method is accurate, stable, and reliable; the different drying methods significantly affect the ployphenol content in T. hemsleyanum leaves, with hot-air drying at 80 ℃ likely representing the optimal drying approach. This finding provides valuable reference for subsequent research on fresh-processing techniques of T. hemsleyanum leaves.
