A new flavanolignan and a new alkane from the Stem bark of Newtonia griffoniana

Two new compounds a flavanolignan (1), and an alkane (2) along with four known compounds including two fatty acid esters (3–4) and two isocoumarins (5–6) were isolated from the methanolic extract of the stem bark of Newtonia griffoniana. Their structures were elucidated using spectroscopic methods including extensive 1-D and 2-D NMR experiments.
