Objective:
To study the isoflavonoids of Iris tectorum.
Methods:
The compounds were isolated by columm chromatography on silica gel and purified by Sephadex LH-20. Structures of these compounds were elucidated by spectral analysis and phytochemical properties.
Results:
Six isoflavonoids were isolated from Iris tectorum, which were tectoridin (I), tectorigenin (II), iristectorin A (III), iristectorigenin A (IV), iristectorin B (V), 5,7,4'-trihydroxy-6,3'-dimethoxy isoflvone (VI).
Conclusion:
Compound VI is isolated from this plant for the first time.
