4], at least 68 distinct xanthones
have been identified in different parts of the G.
Several compounds in the pericarp of the mangosteen have recently been identified, mainly polyphenolic compounds including anthocyanins, xanthones
, garcinone E, 8-deoxygartanin, gartanin, prenylated xanthones
, and condensed tannin [1, 2].
Shan T et in their study concluded that Xanthones
from mangosteen extracts acts natural chemopreventive agents.
which contains a compound called xanthone
, which is thought to have antioxidant properties.
depressant activities of xanthones
from Calophyllum inophyllum and Mesua ferrea.
Globulixanthone F, a new polyoxygenated xanthone
with an isoprenoid group and two antimicrobial biflavonoids from the stem bark of Symphonia globulifera.
kola are biflavonoids, which are potent antioxidants and xanthones
and benezophenones .
The leaves contain good amount of xanthone
and glucoside, mango seed kernels contain a considerable amount of phenolic compounds, lipids, unsaponifiable matter, and a low amount of crude protein .
Mangosteen attenuated inflammation and insulin resistance in cultured human fat storage cells; and an isolated mangosteen xanthone
reduced oxidative damage in rat brains.
Analysis of AgroLabs' mangosteen supplement has revealed that it contains the most active organic compounds of xanthone
and alpha mangostin compared to competing supplements.
The radiation activatable groups R are the same or different and are selected from the group consisting of: a) acetophenone, benzophenone, anthraquinone, xanthone
, thioxanthone, camphorquinone, terephthalophenone benzil, fluorenone, -ketocoumarin and acetophenone-, benzophenone-, anthraquinone-, xanthone
-, thioxanthone-, camphorquinone-, terephthalophenone-, benzil-, fluorenone- and -ketocoumarin-derivatives.
The binding pattern via carbonyl oxygen is only typical for quinone, coumarin, chromone, xanthone
, and kojic acids.
