Abstract

Condensation of salicylic acid and C‐methylphloroglucinol gave the already known 1,3‐dihydroxy‐2‐methylxanthone (1) along with two new compounds: 1,3‐dihydroxy‐4‐methylxanthone (2) and a second one tentatively presented as being 1,3‐dihydroxy‐2‐methyl‐4‐(2‐hydroxybenzoyl)xanthone (3). The UV., IR., NMR, and mass spectra for the two first compounds are reported and their structures discussed on the basis of δ‐values for H(2), H(4), CH~3~(4) and CH~3~(2). The UV. and IR. spectra for the third compound are reported too.
