Characterization of anthocyanin from red sorghum (Sorghum bicolor) bran by liquid chromatography-electron spray ionization mass spectrometry analysis.

In the present study, anthocyanin pigments from red sorghum (Sorghum bicolor) bran were identified and characterized by Liquid Chromatography-Electron Spray Ionization Mass Spectrometry. The individual anthocyanins were identified by comparing their mass spectrometric data and retention times, published data. 3-deoxyanthocyanidins and methyl 3-deoxyanthocyanidins were identified in red sorghum bran. This paper presents complete LCMS profile and MS spectrometric data of red sorghum bran.

The antiproliferative activity of 3-deoxyanthocyanins extracted from red sorghum (Sorghum bicolor) bran through P(53)-dependent and Bcl-2 gene expression in breast cancer cell line.

AIMS: The aim of this study was to investigate the anti proliferative activity of 3-deoxyanthocyanin extracted from red sorghum bran on human breast cancer cell line MCF 7. The confirmatory tests were carried out in vitro through the expression studies of p(53) and (bcl) 2 genes in MCF 7 cells. METHOD: The 3-deoxyanthocyanins were isolated from red sorghum bran and cytotoxic studies were performed in MCF 7 cell line by MTT assay. The mRNA expression levels of p(53) and (bcl) 2 genes were performed using semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) analysis in MCF 7 cells. KEY FINDINGS: On cytotoxic studies, the present data indicates sorghum anthocyanins, which showed 84.09% of inhibition in the proliferation of MCF 7 cells, and the CTC(50) value was 300 µg/ml. The sorghum 3-deoxyanthocyanins induced apoptosis in MCF 7 was mediated by stimulation of the p(53) gene and down regulation of the (bcl) 2 gene. SIGNIFICANCE: The significance of our work was the anthocyanin isolated from red sorghum bran inhibits the proliferation of human breast cancer cell line.
