This work aims to evaluate the quality of seven varieties of Zanthoxylum bungeanum peels based on phenolic compounds, bioactivity, and HPLC fingerprint combined with chemometrics analysis, and pick out the key chemical compounds. As a result, S2 (Fengxian Dahongpao) showed the highest content of total phenolic and rutin, as well as the strongest antioxidant activity, followed by S6 (Hancheng Shizitou). From HPLC fingerprint, eight common characteristic peaks were selected and proved to be effective in controlling the quality of Z. bungeanum peels with the total contribution of 92.775%. The similarity values of each sample ranged between 0.696 and 0.970. In addition, hyperoside was identified as another key chemical indicator for quality evaluation of Z. bungeanum peels by PCA. Accordingly, seven varieties of Z. bungeanum were classified into four groups, among which group 4 (Fengxian Dahongpao, S2) was considered as an outstanding variety, followed by group 1 (S5, S6, and S7) and group 3 (S3 and S4), and group 2 (Fugu late-maturing, S1) was the last one. These results will be helpful to establish an effective and comprehensive evaluation system of Z. bungeanum. PRACTICAL APPLICATION: This study not only provides another index for quality evaluation of Z. bungeanum peels, but it also expects to be a theoretical basis for high-quality germplasm cultivation and the development of Z. bungeanum peels as food additives, pharmaceutical, or health care products.

不同品种花椒品质评价[J]. 基于酚类特征、生物活性和 HPLC 指纹的果皮

【摘要】：目的基于酚类化合物、生物活性、HPLC指纹图谱结合化学计量学分析对7个花椒果皮进行质量评价,筛选出关键化合物。结果表明，S2（奉贤大红袍）的总酚和芦丁含量最高，抗氧化活性最强，其次是S6（韩城狮子头）。从 HPLC 指纹图谱中，选取了 8 个常见特征峰，证明其对花椒果皮品质控制有效，总贡献率为 92.775%。每个样本的相似度值介于 0.696 和 0.970 之间。此外，金丝桃苷被 PCA 确定为金缕梅果皮质量评价的另一个关键化学指标。因此，Z 的七个品种。文竹分为四组，其中第4组（奉贤大红袍，S2）被认为是优良品种，其次是第1组（S5、S6和S7）和第3组（S3和S4），以及第2组（府谷）晚熟，S1）是最后一个。这些结果将有助于建立一个有效的、综合性的金银花评价体系。实际应用：本研究不仅为紫荆果皮品质评价提供了又一指标，有望为紫荆果优质种质培育及作为食品添加剂、医药或保健品的发展提供理论依据。护理产品。S1) 是最后一个。这些结果将有助于建立一个有效的、综合性的金银花评价体系。实际应用：本研究不仅为紫荆果皮品质评价提供了又一指标，有望为紫荆花皮作为食品添加剂、医药或保健品的优质种质培育和发展提供理论依据。护理产品。S1) 是最后一个。这些结果将有助于建立一个有效的、综合性的金银花评价体系。实际应用：本研究不仅为紫荆果皮品质评价提供了又一指标，有望为紫荆花皮作为食品添加剂、医药或保健品的优质种质培育和发展提供理论依据。护理产品。
