Tonkinensines A and B, two novel alkaloids from Sophora tonkinensis
Tetrahedron Letters, 2008Tonkinensines A (1) and B (2), two novel cytisine-type alkaloids that feature the skeleton with a linkage to pterocarpan, were isolated from the roots of Sophora tonkinensis. Their structures and absolute configurations were elucidated by spectroscopic methods, especially X-ray crystal diffraction and CD spectral analysis.

Flavonoids and phenolic acids from the roots of Sophora tonkinensis Gagnep
Biochemical Systematics and Ecology, 2020Abstract Phytochemical study on the roots of Sophora tonkinensis Gagnep. led to the isolation of fifteen compounds, including eleven flavonoids (1–11) and four phenolic acids (12–15). The structures of these compounds were elucidated based on NMR and HR-ESIMS analysis, further supported by comparison with previous literatures. Among them, compounds 2,

Carbohydrate Polymers, 2018
In current study we present two polysaccharides, STRP1 and STRP2, purified from Sophorae tonkinensis Radix via column chromatography. Structural analyses indicated that STRP1 and STRP2 were consisted of mannose, rhamnose, glucuronic acid, glucose, galactose and arabinose in a similar molar ratio with main backbones of (1 → 3)-linked-α-d-Gal and (1 → 4)-

A New Compound from the Endophytic Fungus Xylaria sp. from Sophora tonkinensis
Chemistry of Natural Compounds, 2018A new compound, 6-heptanoyl-4-methoxy-2H-pyran-2-one (1), was isolated from the endophytic fungus Xylaria sp. GDG-102 from the leaf of Sophora tonkinensis. The structure of the new compound was elucidated on the basis of 1D and 2D NMR spectra. Compound 1 showed antimicrobial activity against E. coli and S. aureus with MIC values 50 μg/mL.
