Abstract
Rutolid, a product won from Ruta montana1, has been proved to be a mixture of two isomeres, C16H14O3. The main component (app. 75% of total amt., m.p. 119°C) was shown to be identical with chalepensin2 (from Ruta chalepensis). The isomere, m.p. 127°C, is also a derivative of psoralen; its NMR spectrum proves a cyclopropane ring as an unusual structure element of the side chain. This compound should retain the designation rutolid.
