Five matrine-type alkaloids from Sophora tonkinensis

Journal of Natural Medicines, 2021
Five matrine-type alkaloids (1‒5) including two new compounds (1 and 3) and a new natural product (2) were isolated from the roots of Sophora tonkinesis. Their structures were identified by extensive spectroscopic analysis (UV, IR, HRESIMS and NMR). The absolute configurations of 2 and 3 were determined by X-ray diffraction.

Bioactive quinolizidine alkaloids from Sophora tonkinensis

China Journal of Chinese Materia Medica, 2016
Twelve quinolizidine alkaloids were isolated from Sophora tonkinensis by means of silica gel, preparative MPLC, and preparative HPLC. On analysis of NMR spectroscopic data, their structures were established as 3-(4-hydroxyphenyl)-4-(3-methoxy-4-hydroxyphenyl)-3,4-dehydroquinolizidine(1), lanatine A(2), cermizines C(3), senepodines G(4), senepodines H(5)

Pectic polysaccharides from Radix Sophorae Tonkinensis exhibit significant antioxidant effects

Carbohydrate Polymers, 2021
Two pectic polysaccharides (WRSP-A2b and WRSP-A3a) have been obtained from Radix Sophorae Tonkinensis and comparatively investigated in terms of their physical properties and antioxidant activities. Monosaccharide composition, FT-IR, NMR and enzymatic analyses indicate that both WRSP-A2b (13.6 kDa) and WRSP-A3a (44.6 kDa) consist of homogalacturonan ...

A new flavonol from Sophora tonkinensis

Journal of Asian Natural Products Research, 2007
A new flavonol, tonkinensisol, was isolated from the roots of Sophora tonkinensis, together with three known compounds named as bayin, vitexin and lupeol. Their structures were elucidated on the basis of spectroscopic evidence. Additionally, tonkinensisol showed moderate cytotoxicity suppressing the proliferation of HL-60 cells in vitro.

Three new alkaloids from the roots of Sophora tonkinensis

Journal of Natural Medicines, 2019
A new β-carboline alkaloid (1) and two new matrine-type alkaloids (2 and 3), together with two known alkaloids (4 and 5), were isolated from the roots of Sophora tonkinensis. The new structures were elucidated via extensive analyses of the spectroscopic data (IR, UV, HRESIMS, NMR) and X-ray crystallography.

Isoprenylated flavonoids from the roots of Sophora tonkinensis

Phytochemistry Letters, 2008
Abstract Two new isoprenylated flavanones, tonkinochromanes J ( 1 ) and K ( 2 ), and a new isoprenylated dihydrochalcone, tonkinochromane L ( 3 ), were isolated from the roots of Sophora tonkinensis along with four known compounds ( 4-7 ). Their structures were determined by means of spectroscopic analyses, including HRMS, IR, 1 H and 13 C NMR ...
