langbianensis were studied by GC-MS,it was found that the contents of β-pinene and limonene in fresh needles were significantly higher than those in weak needles.

Seven compounds,including three flavan-3-ols,(+)-catechin(1),(-)-epicatechin(2) and(+)-gallocatechin(3),three flavonoid glycosides,isorhamnetin-3-O-β-D-glucopyranoside(4),astragalin(5) and 2″-O-rhmnosylvitexin(6),and one lignan with the trivial name cedrusin(7),were isolated for the first time from the fresh needles of Larix kaempferi C.
