Present work. Freeze-dried needles were
extracted with acetone-water. Ether and
butanol fractions were separated by repeated
banding on paper. Nine major flavonoids were isolated
(in solution) and identified by chromatographic
and UV spectral data of both the original
and alkaline and/or acid hydrolysis/degradation products as: the 3-glucosides of kaempferol,
quercetin and isorhamnetin, the 3-rutinosides
of quercetin, isorhamnetin and
