Abstract

Abstract Flavonoid glycosides are either lacking or comprise simple profiles in five species representing four genera of the mycotrophic, achlorophyllous Monotropoideae of the Ericaceae. Monotropa hypopitys and Pterospora andromedea afforded no flavonoids while the profiles of M. uniflora Hemitomes conjestum and Sarcodes sanguinea cornprise monoglycosides and digylcosides of kaempferol and quereetin, although not all taxa have all compounds. Hemitomes also possess isorhamnetin 3- O-rutinoside The red colour of Sarcodes arises from a pelargonidin xyloside. The observed flavonoid profiles are more similar to the simple profiles reported for members of the Pyroloideae than they are to those of the Ericaceae sens str.
