25 compounds and their % Absorption values (humans) are given in the paper. These have been provided here.
3 tables with %FA values are given in this paper. One is from Palm et. al. (20 compounds, available on this web-page). Other is from Wessel et. al. (86 compounds, available on this web-page). The third dataset is from Kansy et. al. and is made available here.
A total of 24 drugs and their oral drug absorption in humans (FA) values taken from the 3rd table given in the paper.
Compound "acetylsalicylic acid" was retrieved as "aspirin" from ChemIDplus.

Quantitative Estimation of Drug Absorption in Humans for Passively Transported Compounds on the Basis of Their Physico-chemical Parameters, Quant. Struct.-Act. Relat. 2000, 19 (4), 366-374
Absorption Fraction (FA) values have been given for 32 compounds. These have been picked by the authors from Palm et. al. and Kansy et. al. averaging values for common compounds.
