Mangosteen also has fiber and xanthones
, which can also control blood sugar level.
To perform the phytochemical screening stage was based on the methodology proposed by Matos (1997) which has been crafted with some adaptations in order to carry out prospecting the following allelochemicals: phenols, pyrogalic tannins, phlobaphene tannins, anthocyanin and anthocyanidin, flavones, flavonols, xanthones
, chalcones, aurones, flavononois, leucoantocianidinas, catechins, flavonones, flavonols, xanthones
, steroids and triterpenoids saponins.
Mangosteen contains a class of naturally occurring polyphenol compounds known as xanthones
that are an excellent remedy against various heart diseases.
Three compounds, xanthones
(1.5-dihydroxyxanthone, 5-hydroxy-1-methoxyxanthone, and 6-deoxyjacareubin), were identified by crystallography in 1994 as monoamine oxidase A and B inhibitors (MAO-A and B) (13).
terpenoids, polyketides and xanthones
which have antifungal, antibacterial and cytotoxic activities.8,9 The genus aspergillus contain more than 180 species which live in wide range of habitats.10 Polyketides isolated from an endophytic fungus i.e.
These are naphthodianthrones (hypericin, pseudohypercin), phloroglucinols (hyperforin, adipherforin), flavonoids (rutin, hyperoside, quercitrin) xanthones
from the roots of Hypericum obongifolium Wall.
However, for the ethanol extracts LEESC, BEESC, LEESP, BEESP, and FEESP, the presence of anthraquinones, flavonoids, triterpenes, tannins, and xanthones
Phytochemical analysis of salvilla extracts by ultrahigh-performance liquid chromatography coupled to a photodiode array-electrospray ionization-triple quadrupole showed three subclasses of phenolic acids identified at 280 nm (hydroxyphenolic acids) and 320 nm (hydroxycinnamic acids and phenylethanoids), four subclasses of flavonoids at 280 nm (flavanones), 320 nm (xanthones
and flavones), and 360 nm (flavonols) (Figure 2).
Blanco-Ayala and coworkers conducted an investigation suggesting that the xanthones
Tests were performed for the detection of phenols, flavones, flavonols, xanthones
, catechins, anthocyanins, anthocyanidins, triterpenoids, flavanones, saponins, alkaloids, and tannins.
