The essential oil from the underground parts of Selinum tenuifolium Wall. (Apiaceae) was extracted by hydrodistillation using a Clevenger ‐type apparatus, and analyzed by GC/FID and GC/MS. Nine constituents, representing 97.7% of the total oil, were identified, five of which belong to the class of polyacetylenes. The structures of the compounds 1 – 5 were elucidated by using IR, MS, and 1 H‐ and 13 C‐NMR data after purification by column chromatography. The major constituent detected was nona‐3,5‐diyne ( 1 ; 85.6% of the total volatiles), followed by nona‐3,5‐diyn‐2‐one ( 2 ), nona‐4,6‐diyn‐3‐one ( 3 ), nona‐3,5‐diyn‐2‐ol ( 4 ), and nona‐4,6‐diyn‐3‐ol ( 5 ), accounting for 3.0, 2.5, 2.2, and 3.1% of the total volatiles, respectively. The latter four polyacetylenes, 2 – 5 , were never reported in plants so far, and, therefore should be regarded as novel compounds.
