Phenolics from Larix needles. XII. Seasonal variation of main flavonoids in leaves of L. leptolepis
Acta botanica neerlandica , Volume 25 - Issue 5 p. 349- 359
The metabolic fate of six flavonoids during development and growth of larch needles wai investigated. One flavonoid, dihydroquercetin, appeared to be a special bud-flavonoid. Four compounds were isolated both from buds and leaves, a maximum concentration was found in developing young leaves. A sixth flavonoid, kaempferol-3-(p-coumarylglucoside), was nearly absent in the buds, its highest concentration in the leaves occurred about two months later than that of the other compounds. Only one compound, naringenin-7-glucoside, tended to reaccumulate in late summer.
