从杉木心材的 MeOH 提取物中分离出四种独特的双环[3.3.1]壬二烯甲醇木脂素，分别命名为 lanceolatanins A (1)、B (2)、C (3) 和 D (4)，以及一种先前已知的化合物异落叶松树脂醇 (isolariciresinol) (5)。通过应用各种光谱方法（包括 1D 和 2D-NMR 技术）对其乙酰化衍生物 1a、2a、3a 和 4a 阐明了它们的结构。还讨论了它们可能的生物合成形式。
Four unique bicyclo[3.3.1]nonadienemethanol lignans, designated lanceolatanins A (1), B (2), C (3), and D (4), along with one previously known compound, isolariciresinol (5), were isolated from the MeOH extracts of the heartwood of Cunninghamia lanceolata. Their structures were elucidated by application of various spectroscopic methods, including 1D- and 2D-NMR techniques, to their acetylated derivatives 1a, 2a, 3a, and 4a. Their possible biosynthetic formations are also discussed.
