BISABOLENE AND GUAIANE SESQUITERPENES FROM PULICARIA GLUTINOSA

Article abstract of DOI:10.1016/0031-9422(92)90041-N

Aerial parts of Pulicaria glutinosa yielded three bisabolene sesquiterpenes, puliglutol, puliglutal and puliglutone; structural assignments were based largely on their 2D NMR spectral data.A fourth sesquiterpene, the guaiane cyclo-epoxypuliglene, was also obtained, and its structure and relative stereochemistry were established by X-ray crystallographic analysis. Key words: Pulicaria glutinosa; Compositae; sesquiterpenes; bisabolene; guaiane; X-ray analysis; puliglutol; puliglutal; puliglutone; cyclo-epoxypuliglene; 2D NMR.
