Analysis of alkaloid content in different organs in Sophora flavescens

Journal of Dalian University (2006)

Xin Ren

[Objective] In order to right use Sophora flavescens plant resource,contents of matrine and oxymatrine of various organs of Sophora flavescens from Liaoning province were tested in the present paper.[Methods] TLC method.[Results] Matrine of seeds is the highest in content among all the tested organs,being up to 0.065% of dry weight,then stems (0.034%),roots(0.016%) and leaves(0.013%);The content of oxymatrine in roots is the highest,up to 3.847% of dry weight,and then seeds(1.982%) and stems(0.140%),no oxymatrine was detected in leaves.The alkaloid content is not significantly different between old rough roots more than 1.0cm in diameter and young thin ones of 0.5~1.0cm in diameter.[Conclusions] Contents of alkaloids in Sophora flavescens plants will keep stabilization in mature plants although the plants still grow;Oxymatrine is more than matrine in most organs of Sophora flavescens;Seeds and stems are appropriate organs for matrine extraction.

Isolation and synthesis of a new benzylated alkamide from the roots of Lepidium meyenii

Natural Product Research (2018)

Yanqing Ye Zu-Hong Ma Qiaofen Yang Yanqi Sun Ruiqi Zhang

A new benzylated alkamide, N-(3,4-dimethoxybenzyl)-9Z-oleamide (1), along with two known ones (2 and 3) were isolated from the roots of Lepidium meyenii collected from Lijiang, Yunnan Province of China. Their structures were elucidated by extensive spectroscopic analyses and the new compound further confirmed by a one-step synthesis. All the isolated alkamides were evaluated for their cytotoxicity against five human cancer cell lines. However, no significant activities were detected at concentrations up to 40 μM.
