Forty compounds were isolated from the seeds of Benincasa hispida. Among them, twenty five known compounds were identified their structures as 1,3-dilinoleoyl-2-olein (18), squalene (25), β-sitosterol (26) & stigmasterol (27), β-sitosteryl laurate (28), Δ7-sitosteryl laurate (29), α-spinasteryl laurate (30), cussoracoside C (31), dehydrovomifoliol (32), cucumegastigmane I (33), (2E, 4E)-dihydrophaseic acid (34), (2Z, 4E)-dihydrophaseic acid (35), cyclo(Gly- L-Leu) (36), cyclo(Gly- L-Phe) (37), N5-(4-methoxyphenyl) methyl- L-glutamine (38), vanillin (39), 4-hydroxybenzyl alcohol (40), (E)-ferulic acid (41), trans-coniferyl aldehyde (42), erythro-guaiacylglycerol (43), dihydroconiferyl alcohol (44), trans-coniferyl alcohol (45), glabrol (46), (2S)-liquiritigenin-4'-methyl ether (47) and hyaloserin (48) by 1H-, 13C-, 2D-NMR, MS, UV and IR spectral analyses. The structures were identified by comparison of their physical and spectral data with those reported in the literature. In addition, fifteen unknown compounds have to further identify their structures by spectral and chemical methods.
