Tectoridin abandoned from the flowers of Pueraria thunbergiana is appear to accept beneath hepatoprotective, hypoglycemic, antiallergic and anaphylaxis inhibitory action than its aglycone anatomy tectorigenin. To access tectorigenin, tectoridin was anatomize in the accepted study. However, applied limitations of tectorigenin do abide due to its poor water-solubility.
To access its water-solubility, tectorigenin was sulfonated with sulfuric acerbic (98 wt.%) and alloyed with saturated alkali baptize to aftermath tectorigenin sodium sulfonate. Tectoridin and the two alteration articles were articular by UV, IR, HPLC–MS, 1H NMR and 13C NMR, and the solubility of tectorigenin sodium sulfonate was added about 9-fold than tectorigenin.
The after-effects adapted that the antioxidant action in all the beginning systems apparent the aforementioned adjustment as follows: tectorigenin sodium sulfonate > tectorigenin > tectoridin. Due to the top water-solubility and acceptable antioxidant backdrop with tectorigenin sodium sulfonate, adapted actinic modifications could abundantly advance the biological activities of the by itself occurring products.
