Objective:
To investigate the chemical constituents of Ipomoea batatas.
Methods:
Silica gel column chromatography and Sephadex LH-20 were used to separate and purify the compounds from the EtOAc and n-BuOH soluble fraction of ethanol extracts. The chemical structures were elucidated on the basis of physic-chemical properties and spectral data.
Results:
Four compounds were isolated and identify as citrusin C (1), caffeicacid (2), 3,4-di-O-caffeoylquinic acid (3), 1,2,3,4-tetrahydro-beta-carboline-3-carboylic acid (4).
Conclusion:
Compounds 1-4 are isolated for the first time from I. batatas.

Methods for Studying Drug Absorption: In situ
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,...
