Abstract

Abstract The first complete flavonoid survey of a species of the fern subfamily Platycerioideae is reported. Pyrrosia serpens accumulates predominantly naringenin and eriodictyol 7-neohesperidosides. A range of apigenin and luteolin O-and C-glycosides are also accumulated together with the new flavonol glycoside, kaempferol-3-sophoroside-7-α-l- arabinofuranoside. High alkali-lability of the 7-O-arabinose linkage was observed in the ...
