Aims: To isolate and characterize a new secondary metabolite, zygadenine-N-ribofuranoside derivative from the leaves of water lily (Nymphaeae alba L.). Methodology: The ethanol extract of the dried leaves was partitioned between chloroform and water (1:1), then the chloroform fraction was further partitioned between petroleum ether (60-80°C) and aqueous methanol (1:1). Column chromatography of the chloroform fraction over silica gel (200 mesh) by a gradient elution technique from petroleum ether to chloroform, followed by methanol was carried out. Results: A yellow solid 0.22 g was isolated which was characterized by employing IR, 1D and 2D Original Research Article Njoku et al.; ACSJ, 12(4): 1-5, 2016; Article no.ACSJ.19929 2 NMR techniques spanning H, C, H-H COSY, H-C COSY, HMBC and TOF ESI-mass spectrometry. Conclusion: Zygadenine-N-ribofuranoside derivative isolated, gave m/z 622.4631, corresponding to molecular formula C33H54O9N2.
目的:从睡莲叶中分离并鉴定一种新的次生代谢产物——zygadenine- n -核糖呋喃苷衍生物。方法:将干叶的乙醇提取物用氯仿和水(1:1)进行分馏，再用石油醚(60-80℃)和甲醇水溶液(1:1)进行分馏。采用石油醚-氯仿-甲醇梯度洗脱技术，在硅胶(200目)上对氯仿部分进行了柱层析。结果:分离得到一种0.22 g的黄色固体，通过IR、1D和2D对其进行了表征;学报，12(4):1-5,2016;文章no.ACSJ。199292核磁共振技术跨越氢，碳，H-H COSY, H-C COSY, HMBC和TOF esi质谱。结论:分离得到的zygadenin - n -核呋喃苷衍生物，得到m/z 622.4631，分子式为C33H54O9N2。
