In a number of as yet unpublished experiments it has been found that 2-CI4-acetate or -mevalonate presented to several Labiates in the manner de- scribed gave rise to C14-labeled sterol and triterpenes in all parts of the plants examined. Barring actual transport of sterol or triterpene during the experi- ments (which seems highly unlikely at this time), this information together with the present report gives strong evidence in favor of sterol and triter- pene synthesis in situ for ...
