There have been several studies indicating the enzyme inhibitory activities of phenolic compounds and anthraquinones
. Sawabe et al.
Photodynamic activity of anthraquinones
isolated from Heterophyllaea pustulata Hook f.
In all the three studied species alkaloids, glycosides, starch grains, tannins, anthraquinone
, saponins were present whereas absence of fixed and volatile oils were reported in current study.
The most important are alkaloids, glycosides, saponins, flavonoids, steroids, anthraquinone
and tannic acid.
glycosides from plant parts of Cassia occidentalis.
Meanwhile, we examined the anti-inflammation and neuroprotective effects of CHR, a member of the anthraquinone
family , in the mice who underwent tMCAO.
were suspended in 100% ethanol so that the concentrations in the assays were as listed.
Different plant Tests constituents Test for alkaloids Mayer's test, Dragendroff's test, Wagner's test, and Hager's test Test for proteins and Millon's test, Biuret test, and amino acids ninhydrin test Test for anthraquinones
Modified Borntrager's test Test for flavonoids Ferric chloride test and lead acetate test Test for carbohydrates Molisch's test Test for reducing sugars Fehling's test and Benedict's test Test for saponins Foam formation test Test for tannins Ferric chloride test and lead acetate test Test for steroids, Liebermann-Burchard test, triterpenoids, and Salkowski test, Noller's test, cardiac glycosides Legal's test, Baljet test, and Keller Kiliani's test TABLE 2: Effect on electrolyte excretion in urine.
Saponins detected by all solvents, followed by tannin, reducing sugar (each 7), flavonoids (6), terpenoid (5), alkaloids, anthraquinone
(4 each), whereas, steroids detected by 3 and phlobatannin as well as glycoside isolated by 2 solvents.
Prencese of Anthraquinones
in the extracts are of great importance as Anthraquinones
are considered to be one of the most active agents in metastatic breast cancer.
Commercial aloe beverages that contain little or no latex anthraquinones
may have yielded different outcomes in the subchronic or chronic exposure tests.
