Gilg (Thymelaeaceae), a plant occurring endemically on Socotra Island (Yemen), afforded six novel natural products: two compounds consisting of a flavone and a coumarin moiety connected by a C–C linkage, 7,7′-dihydroxy-3,8′-biscoumarin and three substances with the rare spiro-bis-γ-lactone structure. The structures were elucidated on the basis of their spectroscopic data.Two flavone-coumarin hybrids representing a new structural type of natural products as well as a biscoumarin and three spiro-bis-γ-lactones were isolated from leaves and twigs of Gnidia socotrana (Thymelaeaceae) and identified by spectroscopic data.} }
