Systematical phytochemical investigations on Abies spectabilis afforded 72 chemical constituents. On the basis of physical and spectroscopic data, including 1D and 2D homo- and heteronuclear NMR experiments (heteronuclear single quantum coherence (HSQC), 1H–1H correlation spectroscopy (COSY), heteronuclear multiple bond connectivity (HMBC), and nuclear Overhauser effect spectroscopy (NOESY)), and by comparison with the literature references, they were identified as 3 triterpenoids, 23 diterpenoids, 1 sesquiterpenoid, 13 flavonoids, 12 lignans, and 20 other components. Among these compounds, three were identified as new including abieta-7,13-diene-12α-methoxy-18-oic acid (1), 7α-methoxy-dehydroabietic acid (2), and 5-hydroxy-6-methyl-7,4′-dimethoxyflavone-8-O-β-D-glucopyranoside (3). These three new compounds (13) and all the known terpenoids (428) were tested for cytotoxic activities against four tumor cell lines: A549, COLO-25, QGY-25, and THP-1. However, none of them showed a positive effect (IC50>100 μM).
