Two new glycosides suspensaside C (1) and 2,3,5,6-tetrahydro-jacaranone-4-O-β-d-glucopyranoside (2), together with four known compounds suspensaside A (3), rengynic acid-1′-O-β-d-glucopyranoside (4), forsythoside A (5), and rengynic acid (6), were isolated from the fruits of Forsythia suspense (Thunb.) Vahl. The structures of 1 and 2 were elucidated on the basis of chemical and spectral analysis, including
两种新的糖苷复方糖苷C(1)和2,3,5,6-四氢-car烷酮-4- O -β- d-吡喃葡萄糖苷(2),以及四种已知的化合物复方混悬剂糖苷A(3),肾酸1' - ø -β- d吡喃葡萄糖苷(4),连翘酯苷A(5),和rengynic酸(6),从果实中分离连翘(藤)干旱胁迫下连翘。1和2的结构在化学和光谱分析的基础上进行了阐明,包括1D,2D NMR分析和HR-ESI-MS。测试所有分离株对五种人类癌细胞系(A549,Colo-205,Hep-3B,HL60和KB)的细胞毒性。化合物3表现出对HL-60,Hep-3B和A549癌细胞系的细胞毒性。
