[Studies on chemical constituents from bark of Morus nigra].
OBJECTIVE
To investigate the chemical constituents in the barks of Morus nigra.


METHODS
The nine compounds were isolated and purified by column chromatography over silica gel, LH -20 and preparative HPLC and their structures were identified by various spectroscopic methods.


RESULTS
The nine compounds were isolated and identified as olcancolic acid , apigenin, cyclocommunol, morusin, cyclomorusin, kuwanon C, daucosterol, ursolic acid, 63-sitosterol.


CONCLUSIONS
Olcancolic acid, apingenin, cyclocommunol, morusin, cyclomorusin, kuwanon C, daucosterol were firstly isolated from the M. nigra.
