Effects of Chrysin on radiation sensitization in human gastric cancer cells SGC7901

High speed counter-current chromatography (HSCCC) was successfully used for the isolation and purification of baicalein and chrysin from the extracts of Oroxylum indicum using stepwise elution with a pair of two-phase solvents systems composed of light petroleum-ethyl acetate-methanol-water (5∶5∶5∶5 and 5∶5∶7∶3,V/V).

leaves by solvent extraction and column chromatography,and identified as quercetin,chrysin,apigenin,kaempferol,and luteolin.

Objective To observe the effect of 5,7-dimethorychysin(dMChR) in inhibition of human acute myeloid leukemia cell (HL-60) proliferation and in induction of HL-60 cell apoptosis, and approached if activation of PPARγand regulation of PTEN-Akt signal transduction pathway were involved in the effect of dMChR on HL-60 cells.

Study on the Interaction between 5,7-Dihydroxyflavone and Bovine Serum Albumin;

5,7-dihydroxyflavone molecularly imprinted polymers(MIP) was prepared by precipitation polymerization,its absorption capability was detected by UV-spectrometry.

Synthesis and bactericidal activity of 5,7-dihydroxy-flavanone;
