Leaves of Larix leptolepis trees and seedlings were examined for flavonoids and for wax constituents by high-performance liquid chromatography or by gas chromatography. Within the species, due to differences in genotype, there is a great variability in the chemical composition of the flavonoids but less in that of the wax constituents of the needles.
