Abstract
Complexes of copper (II) with hesperetin, naringenin, and apigenin of general composition [CuL(2)(H(2)O)(2)] nH(2)O (1-3) have been synthesized and characterized by elemental analysis, UV-Vis, FT-IR, ESI-MS, and TG-DTG thermal analysis. The free ligands and the metal complexes have been tested in vitro against human cancer cell lines hepatocellular carcinoma (HepG-2), gastric carcinomas (SGC-7901), and cervical carcinoma (HeLa). Complexes 1 and 3 were found to exhibit growth inhibition of SGC-7901 and HepG2 cell lines with respect to the free ligands; the inhibitory rate of complex 1 is 43.2% and 43.8%, while complex 3 is 46% and 36%, respectively. The interactions of complex 1 and its ligand Hsp with calf thymus DNA were investigated by UV-Vis, fluorescence, and CD spectra. Both complex 1 and Hsp were found to bind DNA in intercalation modes, and the binding affinity of complex 1 was stronger than that of free ligand.

Abstract
Detailed chemical investigation of the herb Sarcopyramis bodinieri var. delicate resulted in the isolation of two new flavonol glycosides, namely, isorhamnetin-3-O-(6''-OE-feruloyl)-beta-D-glucopyranoside (1) and isorhamnetin-3-O-(6''-O-E-feruloyl)-beta-Dgalactopyranoside (2). In addition, four known compounds, quercetin-3-O-(6''-acetyl)-beta-Dglucopyranoside (3), isorhamnetin-3-O-(6''-acetyl)-beta-D-glucopyranoside (4), quercetin-3-O-(6''-O-E-p-coumaroyl)-beta-D-glucopyranoside (5), and isorhamnetin-3-O-(6''-O-E-pcoumaroyl)-beta-D-glucopyranoside (6) were obtained. The structures of the new isolates were determined by extensive spectroscopic analysis.
