title: New depside from Citrus reticulata Blanco.
abstract: A new depside, named depcitrus A (1), and 31 known compounds were isolated from the peels, leaves and branch barks of Citrus reticulata Blanco. Methylation of the high polarity fractions from the branch barks and peels gave one new methylated compound named depcitrus B (14) and five known compounds. Their structures were established based on spectroscopic evidence. The antioxidant, antimicrobial and cytotoxic activities of some pure compounds were evaluated.
