& Dohme’s preparation is thought to be due to the presence of a 
relatively large amount of the glyceride of petroselinie acid, 
which is stated by von Gerichten to have a saponification value 
of 191.2. See under “'Chemistry of the drug and oleoresin.” 
Tables showing the saponification values of the preparations 
examined in the laboratory follow. For comparison with the 
foregoing data, the values obtained for the so-called liquid 
apiols have also been included in these tables.

Iodine value: The iodine values as found for the oleoresins 
prepared in the laboratory are given in the first of the tables 
which follow. It will be observed that there is a considerable 
difference in these values due to the nature of the solvent em¬ 
ployed in extracting the drug. The low iodine value observed 
for the preparation made by Sharp & Dohme is to be attributed 
to the partial oxidation of the unsaturated glycerides. For 
comparison, the iodine values of two samples of so-called 
“liquid apiols”( preparations made with alcohol) have been 
included in the tables which follow.
