RESUMEN
In the title compound, C(11)H(11)NO(3), the dihedral angle between the benzene ring and the cyclo-propane ring is 63.2â (1)°. In the crystal, mol-ecules are linked through classical cyclic carb-oxy-lic acid O-Hâ¯O hydrogen-bond inter-actions [graph set R(2) (2)(8)] giving centrosymmetric dimers which are extended along the b-axis direction through amide N-Hâ¯O hydrogen-bond inter-actions, giving one-dimensional ribbon structures. Weak C-Hâ¯O inter-actions are also present in the structure.
RESUMEN
Three new xanthones, garcinolic acid (1), 10α-ethoxy-9,10-dihydromorellic acid (2), and 10α-ethoxy-9,10-dihydrogambogenic acid (3), along with six known compounds were isolated from the resin of Garcinia hanburyi. These compounds were tested for their cytotoxicities against A549, HCT116, SK-BR-3 and HepG2, and showed high inhibitory effects on the cell lines.
