摘要

枸杞果实的植物化学研究。鉴定了8种未描述的苯丙苷，即荔枝苷A-H(1-8)，以及5种已知化合物（9-13）。通过详细的光谱数据分析（hresms， 1D和2D NMR）和酸水解实验对新化合物的结构进行了鉴定。化合物1、3 ~ 6、8 ~ 10、12、13在50 μM时能显著增加胰岛素抵抗HepG2细胞的葡萄糖消耗，化合物1、9能提高胰岛素抵抗HepG2细胞的葡萄糖摄取能力，提高己糖激酶和丙酮酸激酶活性。此外，化合物9对α-葡萄糖苷酶具有良好的抑制活性，IC50值为16.8 μM，与阳性对照阿卡波糖（300.0 μM）相当。

Phenylpropanoid glycosides from the fruits of Lycium chinense and their potential anti-diabetic activity

Phytochemical study of the fruits of Lycium chinense Mill. allowed the identification of eight undescribed phenylpropanoid glycosides, namely lychinosides A-H (1–8), along with five known compounds (9–13). The structures of the new compounds were elucidated through detailed analysis of spectroscopic data (HRESIMS, 1D and 2D NMR) and acid hydrolysis experiment. Compounds 1, 3–6, 8–10, 12, and 13 could significantly increase the glucose consumption in insulin-resistant HepG2 cells at 50 μM, and compounds 1 and 9 could improve the glucose uptake capacity of insulin-resistant HepG2 cells and enhance the hexokinase and pyruvate kinase activities. In addition, compound 9 exhibited excellent inhibitory activities against α-glucosidase with an IC₅₀ value of 16.8 μM, comparable to that of the positive control acarbose (300.0 μM).
