- W3044008979 abstract "Ugni molinae Turcz. Myrtaceae (Murtilla) is a plant native to Chile. There is evidence about the antiproliferative compounds present in fruits, but there is no evidence on the antiproliferative activity of the compounds in the leaves. These compounds have importance because they predominate in the popular form of ingestion of leaves. In the present study, the identification of water-soluble components of leaves of U. molinae and a fractionation were carried out to determine the effect on viability of gastric adenocarcinoma cells (AGS).A decoct of leaves was performed at 1%. For the separation of fractions, a countercurrent system (CPC) was used. Leaves were collected and identified by thinlayer chromatography and liquid chromatography-mass spectrometry (HPLC MS/MS). Samples were evaluated to determine the viability of AGS cells by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromidefor (MTT) assays. Three large fractions were identified. In the first one, the phenolic compounds of medium polarity and low molecular weight (phenolic acids) are found. In The second fraction shows low concentrations of phenolic compounds with greater molecular weight (glycosylated and gallolylated flavonoids); and the third, has a predominance of hydrolysable tannins, procianidins and other highly hydrophilic compounds. About cell viability, it was found that, the 1% extract is the one that presented the best effects on cell viability inhibition, in comparation to tannin and flavonoid fractions.In conclusion, there is synergy in the compounds present in the aqueous extract, which causes greater inhibition of cell viability, unlike the separated fractions." @default.
