| Abstract: | Abstract Two compounds isolated from the aerial parts of Verbesina turbacensis H.B.K, are reported in this work. Both compounds crystallize in the orthorhombic system, space group P212121. Compound (1), 6β-cinnamoyloxy]-3β,4α-dihydroxyeudesmane, formula C24H34O4, has unit cell parameters a = 9.6234(2), b = 12.3137(3) and c = 18.6277(5) Å, V = 2207.38(9) Å3, Z = 4. On the other hand, 6β-cinnamoyloxy]-eudesman-15-oic acid (2), formula C24H32O4, has cell parameters a = 8.7035(3), b = 14.2020(4), c = 17.1590(5) Å, V = 2120.97(11) Å3, Z = 4. |
