Table II. Unusual Glycosides from Xenoblotlcs In Plants...

L. densiflora produced methoxylated flavonoid glycosides that are quite unusual in the plant kingdom and often play an important role of protection from attacks by herbivores or pathogens, so that their biosynthesis could be related to local environmental factors [14]. 

Gentiobiose glycosides of (R)- and (S)-terosachrysone and anthraquinones have been isolated from toadstools,and a sophorose-containing flavanone has been found in the stem bark of Ochna calodendron An unusual disaccharide derivative, a tricyclic bisglycoside of p-D-glucopyranose and 2-C-hydro-methyl-D-threose has been isolated from a plant source. (See this chapter. Section 1.4.9).
