Summary
1. On the basis of a study of the UV absorption spectra of pentacyclic triterpenoids in conc. sulfuric acid, a method has been developed for the quantitative determination of triterpenoids in the foliage of wild-growing species ofThymus and cultivated thyme.
2. The method is distinguished from existing ones by its rapidity and low consumption of reagents.
