[Study on the chemical constituents of mori cortex].

OBJECTIVE

To study the chemical constituents of Mori Cortex.

METHODS

The compounds from the dichloromethane-methanol extracts were isolated by the silica gel column chromatography, and their structures were identified by the spectral analysis and chemical evidence.

RESULTS

Eight compounds were obtained and their structures were identified as 3-acetyl-beta-amyranol (1), neotocopherol (2), alpha-amyrin (3), clionasterol (4), betulinic acid (5), moracin O (6), morusin (7) and morusignin L (8).

CONCLUSION

Componds 2 and 4 are obtained from this plant for the first time.
