The book in hand provides base-line information on the chemical constituents of Primula macrophylla D. Don like isolation and characterization of nine compounds namely ß-sitosterol, flavone, 2'-methoxy flavone, 3'-methoxy flavone, 3.3'-dihydroxy chalcone, ß-sitosterol glucoside, 2'-hydroxy 7-O- ß- D-glucoside "macrophylloside" and two triterpenoid saponins, PM-F and PM-F2 . Four compounds namely 3.3'-dihydroxy chalcone, macrophylloside, PM-F and PM-F2 were new while 2'-methoxy flavone and 3'- methoxy flavone are reported for the first time from the family Primulaceae and are very rare. ß- sitosterol, ß-sitosterol glucoside and flavone are reported for the first time from this plant in this part of the world. The book will certainly help the graduate, post-graduate students, pharmacologists and researchers as useful guideline in their respective fields.
