โœฆ Synopsis

RECENT studies have demonstrated that mass spectrometry may be a powerful adjunct to the structure elucidation of polycyclic natural products such as alkaloids3'le and steroids.5 These developments have been made possible by improved inlet systems, which permitted the vaporization in an undecomposed state of relatively non-volatile substances. We should now like to report some of our results with pentacyclic triterpenes ? usual melting NO.7

A RECENT investigation2 of the leaves of Vinca difformis has led to an alkaloid mixture, which could be resolved upon chromatography. One of the new alkaloids, vincadifformine, forms the subject of the present communication since its biogenetically very interesting structure (I) was elucidated large
