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.

The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
