One novel dimeric coumarin analog, fatouapilosin (1), together with 18 known compounds, have been isolated from the whole plants of Fatoua pilosa. The structures of these isolates were elucidated by means of spectroscopic techniques (UV, IR, MS, 1H- and 13C-NMR, DEPT, COSY, NOESY, HSQC, HMBC, and MS
Six new prenylcoumarins, (+)-fatouain A (1), (-)-fatouain B (2), (+)-fatouain C (3), (-)-fatouain D (4), (+)-fatouain E (5), and (-)-fatouain F (6), along with two new bis-prenylcoumarins, (+)-fatouain G (7) and (+)-fatouain H (8), have been isolated from whole plants of Fatoua pilosa. The relative
Three new alkylated chalcones, villosins A - C (1 - 3), five known analogues, together with ten known coumarins, were isolated from Fatoua villosa. The structures of the new compounds were elucidated by extensive spectroscopic analysis, including 1D-, 2D-NMR, and MS data. Compounds 1 - 3 showed
