According to a study published by "Frontiers in plant science", the R.d-60 fraction from ethyl acetate extracts of Rhamnus davuricica showed higher inhibitory rates against SGC-7901 and HT-29 compared with the R.d-30 fraction in vitro. Using a method based on bio-affinity ultrafiltration and HPLC-ESI-MS/MS, eight ligands were identified from this fraction. Among these, six ligands with higher enrichment factors showed more potential antitumor activity. Two representative candidates, apigenin and quercetin, were used in antiproliferative assays to determine IC50 values against SGC-7901, HT-29, and Hep G2 cells. Structure-activity relationships revealed that flavones containing a C2-C3 double bond of the C ring exhibited higher bio-affinities to Topo I.
