[Studies on chemical constituents of fructus broussonetiae].

OBJECTIVE

To study the chemical constituents of Fructus Broussonetiae.

METHODS

Column chromatography with silic gel was employed to isolate and purify the 80% alcohol extract of Fructus Broussonetia, and the constituents were identified by spectral methods.

RESULTS

Six compounds were isolated from 80% ethanol extract. Their structures were identified as Isoterihanine (1), Chelerythrine (2), Trillin (3), Sucrose (4), beta-sitosterol (5) and Fucosterol (6).

CONCLUSION

These compounds are isolated from Fructus Broussonetiae for the first time.
