Three new isoflavone glucosides, kudonol A-C (-), two new ester derivatives of phenylpropanoid, kudolignan A and B (-) and five known compounds, (-)-maackiain (), neoliquiritin (), methyl 4-coumarate (), methyl ferulate () and (+)-wikstromol (), were isolated from an extract of dried seeds of the traditional Chinese medicinal plant L. Their structures were established by NMR and HRESIMS data analyses. The monosaccharide part's configuration of isoflavone glucosides was confirmed by acid hydrolysis and analyzed by a JAsco OR-4090 chiral detector, comparing it to standard substance D-glucose. The cytotoxicity effects against HeLa, Hep3B, MCF-7 and H1299 cells were tested by CCK-8 assay.

The first total syntheses of four isoflavone glucosides, tectoridin (), tectoridin A (), tectorigenin 7--β-d-glucopyranosyl-12--β-d-glucopyranoside (), and isotectroigenin 7--β-d-glucopyranoside (), have been accomplished. Key steps in our synthetic approach include a regioselective halogenation reaction, followed by methanolysis to introduce the -OCH group into isoflavone frameworks and a PTC-promoted stereoselective glycosidation to establish glycosidic bonds. The synthesized isoflavone glucosides (-) and their corresponding aglycones ( and ) were evaluated for anti-inflammatory activity against nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1 β (IL-1β) in lipopolysaccharide (LPS)-induced RAW264.

The traditional Chinese medicine (TCM) formula, gegen-huangqi (GH) decoction, has been employed for over 200 years, notably for its therapeutic effects in treating conditions such as atherosclerosis and diabetes mellitus. Despite its long-standing use, comprehensive studies on the chemical constituents of GH and their in vivo pharmacokinetics (PK) remain limited. This study aimed to profile the bioactive compounds present in GH decoction and to explore their PK characteristics using HPLC-Q-TOF-MS/MS.
