  Detailed gas phase fragmentation behavior of a furo-furan lactone 1 with a novel skeleton of three fused furan rings isolated from medicinally important Heliotropium eichwaldi plant was studied. Elucidation of the major fragmentation routes was performed using CID-MS/MS analysis, insource-MSn fragmentation, parent ion scan analysis and exact mass measurements using electrospray ionization quadropole time-of-flight mass spectrometry (ESI-QqTOF-MS/ MS) hybrid instrument in negative and positive ion modes. Analysis showed the presence of [M+H]+ and [M-H]- at m/z 275 and m/z 273, respectively. Low-energy collision induced dissociation tandem mass spectrometric analysis (CIDMS/ MS) in both ion modes showed several characteristics losses of carbon monoxide and water molecules along with characteristic losses of acetaldehyde, formaldehyde, formic acid and ca..
