Objective:
To study the chemical constituents of Buddleja davidii.
Methods:
The constituents were isolated and purified by silica gel column chromatography, polyamide column chromatography and macroporous adsorption resin and their structures were identified by spectroscopic analysis.
Results:
Eight compounds were elucidated as : Cranioside A (1), Eutigoside A (2), 1-O-4-Dimethoxyphenylethyl-4-O-3,4-dimethoxyphenylethy-beta-D-glucopyranoside (3), Isomartynoside (4'), 4"-O-Acetylmartynoside (5), Stigmasterol glueoside (6), beta-Sitosterol (7), Daucosterol (8).
Conclusion:
All these compounds 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,...
