Two new hydroxy chalcone derivatives from Thymus cilicicus

The aerial part of Thymus cilicicus Linn. (Labiatae) has afforded two new hydroxy chalcone derivatives, characterized as 4, 2', 4', 6', 7, 8-hexahydroxy-7 (8)-dihydro-chalcone (1), and 3, 4, 2', 4', 6', 7, 8-heptahydroxy-7 (8)-dihydro-chalcone (2). The structures of the isolated compounds have been elucidated based on various spectral studies.
