Five new α-tetralone glycosides, juglanbiosides A-E (1–5), together with an α-tetralone derivative (15) and nine known 1,4-naphthoquinones (6–14) were isolated from the 95% EtOH extract of green walnut husks of Juglans mandshurica Maxim. Their structures were elucidated by comprehensive spectroscopic methods (1H, 13C NMR, DEPT, HSQC, HMBC, CD, HR-ESI-MS). In vitro cytotoxicities of all the isolated
从95%的绿色核桃壳乙醇提取物中分离出5种新的α-四氢萘酮糖,ju兰糖苷AE(1-5),以及α-四氢萘酮衍生物(15)和9种已知的1,4-萘醌(6-14)。的胡桃楸马克西姆。通过全面的光谱方法(1 H,13 C NMR,DEPT,HSQC,HMBC,CD,HR-ESI-MS)阐明了它们的结构。在体外的所有分离的化合物的细胞毒性进行了针对BGC-823评估,HCT-15和K562癌细胞系。
