This Comment critically addresses the article by Gao et al. (Gao, K., et al. J. Agric. Food Chem. 2015, 63, 1067−1075), providing the structural elucidation of three phenolamide dimers (neolignanamides) from the fruits of Lycium barbarum. A more recent article published by Chen et al. (Chen, H., et al. J. Agric. Food Chem. 2023, 71, 11080−11093) incorporates these structures into further research on the bioactivity of these compounds. Although the analytical techniques used by Gao et al. are adequate, in our opinion, the nuclear magnetic resonance (NMR) spectroscopic data have not been interpreted correctly, resulting in incorrect structures for three neolignanamides from the fruits of L. barbarum. In this Comment, an alternative interpretation of the NMR spectroscopic data and the corresponding structures are proposed. The proposed structures feature linkage types that are much more common for neolignanamides than the linkage types in the originally reported structures of these compounds.

评《枸杞子中酚酰胺的三种新二聚体和两种单体及其抗氧化活性》

此评论批评了高等人的文章。 （高K.，等人。J.阿格里克。食品化学。 2015 , 63 , 1067−1075)，提供了来自枸杞果实的三种酚酰胺二聚体（新木脂素酰胺）的结构阐明。 Chen等人最近发表的一篇文章。 （陈，H.，等人。J.阿格里克。食品化学。 2023 , 71 , 11080−11093）将这些结构纳入这些化合物生物活性的进一步研究中。尽管高等人使用的分析技术。我们认为，核磁共振（NMR）波谱数据没有被正确解释，导致来自L. barbarum果实的三种新木脂素酰胺的结构不正确。在本评论中，提出了核磁共振波谱数据的替代解释和相应的结构。所提出的结构的特征是新木脂酰胺类的连接类型比这些化合物最初报道的结构中的连接类型更常见。
