摘要
目的对一叶萩的生物碱类成分进行研究。方法采用各种色谱技术对一叶萩的总生物碱部位进行分离,应用理化常数和波谱技术(NMR、MS等)鉴定化合物的结构。结果自一叶萩枝叶的总碱部位中分离得到2个新的生物碱类化合物,分别命名为叶下珠碱B(phyllanthidine B,4α-methoxy-phyllanthidine,Ⅰ)和一叶萩醇D(securi-nolD,14β-hydroxyviroallosecurinine,Ⅱ)。结论化合物和均为新化合物。
Objective To investigate the total alkaloids in chemical constituents from the tender leaves and twigs of Securinega suffruticosa. Methods Column chromatographies were used to separate the total alkaloids in the tender leaves and twigs of S. suffruticosa whose structures were elucidated by means of physicochemical properties and spectral data. Results Two new alkaloids named as phyllanthidine B, 4α- methoxy-phyllanthidine （ Ⅰ ） and securinol D, 14β-hydroxyviroallosecurinine （Ⅱ） were isolated and identi- fied. Conclusion The two alkaloids, compounds Ⅰ and Ⅱ , are new ones.
