Ι. ΜΕΛΕΤΗ ΤΩΝ ΧΗΜΙΚΩΝ ΣΥΣΤΑΤΙΚΩΝ ΤΟΥ ΦΥΤΟΥ CISTUS INCANUS SUBSP. CRETICUS (L.) HEYWOOD ΙΙ. ΑΠΟΜΟΝΩΣΗ-ΔΟΜΗ-ΣΥΝΘΕΣΗ ΝΕΟΥ ΦΛΑΒΟΝΟΕΙΔΟΥΣ ΤΟΥ ΦΥΤΟΥ KALANCHOE PROLIFERA R. HAMET

THE LEAVES OF CISTUS INCANUS SUBSP CRETICUS (L.) HEYWOOD COLLECTED IN CRETE ANDSTUDIED IN THE FIRST PART OF THIS THESIS. FROM THE PETROLERUM ETHER EXTRACT AND ETHER EXTRACT SEVEN LABDANE -TYPE DITERPENES HAVE BENEN ISOLATED AND IDENTIFIED. THE STRUCTURES OF ALL THE COMPOUNDS WERE DETERMINED BY MS (EI), (CID), H-NMR. FROM THE 95% ALCOHOL EXTRACT WERE ISOLATED SEVEN POLYPHENOLIC SUBSTANCES. INTHE SECOND PART OF THIS THESIS WERE STUDIED THE STRUCTURE AND THE SYNTHESIS OFA NEW FLAVONOID GLYCOSIDE (QUERCETIN-3[2-0-B-D-GLUCOPYRONOSIDE 1->2 B-D- XYLOPYRANOCIDE]. THE STEREOCHEMISTRY AND THE CONFORMATION OF THE XYLOSE ARE DESCRIBED PHASE TRANSFERT CATALYSIS APPEARS TO BE A SIMPLER AND EASIER METHOD FOR THE SYNTHESIS OF FLAVONOID GLYCOSIDE. THE YIELDS OBSERVED ARE GENERALLY HIGHER THAN THOSE REPORTED BY CLASSIC METHODS.
