Abstract: Needles from Pinus sylvestris L. were analyzed for their
flavonoid content.  Thirty five useful fractions obtained through
column chromatography and the analysis by two dimensional paper
chromatography allowed for the identification of seven types of
flavonoids  in  the  sample.    The  flavonoids  found  included:
flavones,  flavonols,  isoflavones, dihydroflavonols,  flavanones
chalcones  and  anthocyanidins.    The  differentiation  of  these
compounds depends on the position of sugars and hydroxyl groups
attached to the flavonoids present.   These substituents cause
colours detected by U.V.  light to shift wavelengths,  thereby
constituting different compounds.
