A new furfural derivative, pogoscafuran A ( 1 ), a new natural product, HMF levulinate ( 2 ), together with four known compounds ( 3 – 6 ) were isolated from an extract of the leaves and stems of  Pogostemon cablin  (Blanco) Benth. Their structures were elucidated on the basis of extensive spectroscopic analyses and single-crystal X-ray crystallography. Compound  1  was the first example of natural furfural derivative with a unique C5–C1′ linkage between a molecule of furfural and 3-methyl-2-cyclopentenone moiety. The plausible biogenetic pathway for the new compound  1  was proposed. All these isolated compounds were tested for their inhibitory effects on the nitric oxide (NO) production induced by lipopolysaccharide in RAW264.7 cells, and only compound  1  exhibited weak inhibitory activity.
