From the stems and leaves ofRh. caucasicum Pall. campanullin, friedelin, and epifriedelinol have been isolated and identified, and from the stems and leaves ofRh. ledebourii Pojark campanullin, β-sito-sterol, and betulin.
The chromatographic mobility of 20 triterpenoids on the stationary phase SE-30 has been studied.
It has been shown that the GLC method permits some preliminary conclusions to be obtained concerning the triterpene composition of rhododendron extracts.
