“…It should be noted that 5 is a fairly common compound in Gentianales and Cornales, but 6 and 7 have much more limited distributions, so far being recorded elsewhere only in a few species of Dipsacaceae (Jensen et al, 1975;Jensen, 1992). XANTHONES ) have a rather restricted occurrence among higher plants, being found almost exclusively in Guttiferae and Gentianaceae (Carpenter et al, 1969;Sultanbava, 1980;Mandal et al, 1992a). Xanthones are sometimes found as the parent polyhydroxylated compounds but more often with a varying degree of substitution at the oxygen atoms.…”

“…These are further subdivided into various categories such as mono, di, tri, tetra, penta, and hexa oxygenated depending on the level of oxygenation [21][22][23]. For example, 2-hydroxyxanthone (3), 2-hydroxy-1-methoxyxanthone (4).…”

Xanthones are one of the biggest classes of compounds in natural product chemistry. A number of xanthones have been isolated from natural sources of higher plants such as fungi, ferns, and lichens. Synthetic analogs of xanthones have shown a large number of pharmacological properties such as antioxidant, anti-inflammatory, antidiabetics, antihistamine, antitumoral, antiulcer, and algicidal. Moreover, they also find usages in photodynamic therapy, laser technology, and dyes. This review lays stress on various solvents, catalyst and synthetic route for synthesis of xanthones, benzoxanthones analogs. The review has also focused on the classifications of xanthone as well as extensively studied biological properties of the xanthones and benzoxanthones analogs.
