Determination of quinolizidine alkaloids in Sophora tonkinensis by HPCE

Phytochemical Analysis, 2005
AbstractA simple, rapid and reliable high‐performance capillary electrophoresis method has been developed to determine quantitatively the alkaloid content of Sophora tonkinensis, a Chinese herb commonly known as shan‐dou‐gen. A total of seven quinolizidine alkaloids (cytisine, sophocarpine, matrine, lehmannine, sophoranol, oxymatrine and ...

Quinolizidine alkaloids from Sophora tonkinensis and their anti-inflammatory activities

Fitoterapia, 2019
Two new quinolizidine-based alkaloids (2 and 12), along with ten known ones (1, 3-11) were isolated from the roots of S. tonkinensis. Their structures were determined by spectroscopic data (including NMR, MS, IR, and UV), X-ray single crystal diffraction, electronic circular dichroism analyses (ECD), and comparing with related literatures. Compounds 1,

NMR spectral assignments of isoprenylated flavanones from Sophora tonkinensis

Magnetic Resonance in Chemistry, 2008
AbstractThe phytochemical investigation of extracts from the roots of Sophora tonkinensis yielded three new isoprenylated flavanones, the tonkinochromanes F (2), G (3), and H (5), along with four known compounds. Structural elucidation of the compounds were established on the basis of spectral data, particularly by the use of 1D NMR and several 2D ...

Anti-inflammatory quinolizidine alkaloids from the aerial parts of Sophora tonkinensis

Phytochemistry Letters, 2021
Abstract Seventeen quinolizidine alkaloids, including two new ones, 5-hydoxy-7,11-dehydromatrine (1) and 11-hydroxylupanine (2), were isolated from the aerial parts of Sophora tonkinensis. The structures of the isolates were elucidated using 1D and 2D NMR analyses, as well as HR-ESI-MS spectroscopic data.

Molecularly imprinted solid-phase extraction of matrine from radix Sophorae tonkinensis

The Analyst, 2011
In the study, molecularly imprinted polymers (MIPs) with special molecular recognition properties of matrine (MAT) were prepared in our lab, using melamine-urea-formaldehyde (MUF) as the functional monomer and matrine as the template. An equilibrium binding experiment was performed to investigate the binding ability of the MIPs, and indicated that the ...
