indole alkaloid diglycosides named isatigotindolediosides A-F (1–6), along with three known analogs (7–9), were isolated from an aqueous extract of the Isatis indigotica roots (ban lan gen). Their structures including the absolute configurations were determined by comprehensive spectroscopic data analysis, combined with enzyme or acid hydrolysis, and comparison of experimental circular dichroism (CD)
命名isatigotindolediosides六个新的吲哚生物碱diglycosides AF(1-6)中,用三个已知类似物(沿7-9),从该的含水提取物中分离菘蓝根(禁止LAN GEN)。通过全面的光谱数据分析,结合酶或酸水解以及比较实验圆二色性(CD)和计算出的电子圆二色性(ECD)光谱来确定其结构,包括绝对构型。在初步试验中,化合物3,5,和8显示针对手足口病毒B3的抗病毒活性。
