ACYLATED 6-HYDROXYLUTEOLIN DIGLUCOSIDES FROM GLOBULARIA ELONGATA

Article abstract of DOI:10.1016/0031-9422(88)80626-5

Three flavonoid aglycones and three glycosides have been isolated from the aerial parts of Globularia elongata.The aglycones were identified as apigenin, luteolin and 6-hydroxyluteolin.Structural elucidation of the glycosides employing spectroscopic methods (UV, IR, ¹H NMR, ¹³C NMR, FDMS) revealed 6-hydroxyluteolin 7-sophoroside and two new acylated derivatives, 6-hydroxyluteolin 7-6'''-caffeoylsophoroside and its p-coumaroyl analogue.Key Word Index - Globularia elongata; Globulariaceae; 6-hydroxyluteolin 7-sophoroside; 6-hydroxyluteolin 7-6'''-caffeoylsophoroside; 6-hydroxyluteolin 7-6'''-p-coumaroylsophoroside; ¹H NMR; ¹³C NMR, FDMS.
