Further chemical study led to two new A-seco-rearranged lanostane triterpenoid derivatives (1-2) and one known compound Abiesanolide C (3) from the ethyl acetate (EtOAc) soluble fraction of the MeOH extract of Abies sachalinensis needles. The new compounds were identified as 3,4-seco-8-($14{ ightarrow}13R$)abeo-17, l3-friedo-$9{eta}$-lanosta-4(28), 7, 14, 24-tetraen- 26,23-olide-23-hydroxy-3-oic acid and methyl-3,4-seco-8-($14{ ightarrow}13R$) abeo-17,13-friedo-$9{eta}$-lanosta-4(28), 7, 14, 24-tetraen-26,23-olide-23-hydroxy-3-oate, respectively. Structural determination of these compounds were carried out by the spectral studies especially by the two digital (2D)-NMR and high-resolution (HR)-MS experiences.
