Five isoflavones were isolated from the root of Caragana microphylla Lam. and the structures have been identified by means of chemical and physical methods. The isoflavones are 7-hydroxy-4'-methoxyisoflavone(formononetin), formononetin-7-O-β-glucoside(ononin), 7-hydroxy-3', 4'-methylenedioxyisoflavone(pseudobaptigenin), 7-O-β-glucuopyranosyloxy-3'-hydroxy-4'-methoxyi-soflavone(calycosin-7-O-β-gluc-oside) and maackiain.

A series of 2-substituted-1,4-bis(dimethylamino)-9,10-anthraquinone derivatives were synthesized and their in vitro antiproliferative activities against p388 mouse leukemic tumor cells were evaluated. In addition, the effect of substituents on the phenyl ring was investigated. Among the derivatives tested, seven showed a high antiproliferative effect and three showed a moderate effect. In addition, introduction of a series of substituted phenyl groups into 1,4-bis(dimethylamino)-9,10-anthraquinone at 2-position were shown to enhance its antiproliferative activity. The antiproliferative activity also increased upon substitution of the benzene ring by an electron donating group such as an amine or methoxyl group.

An ion-imprinted polymer (IIP) with monophosphonic groups was prepared by thermal copolymerization. Bis(2-methacryloxyethyl) phosphate (BMAOP) was used as functional monomer to react with Fe3+ in dimethyl sulfoxide (DMSO). Ethylene glycol dimethacrylate (EGDMA) was used as cross-linker during polymerization process. A suitable molar ratio of BMAOP to Fe3+ was investigated by UV/Vis/NIR Spectrometer and ICP-OES. The obtained results showed that the monophosphonic groups could be selectively combined with Fe3+ in solutions containing other coexisting ions, and the selectivity could be further enhanced by ion-imprinted process. The prepared IIP was used for removing trace Fe3+ from high concentration basic chromium sulfate solutions. After adsorption process, the concentration of Fe3+ could be reduced from 4.486mg L1 to 0.171mg L1, which was much lower than the concentration in the solution treated by non-imprinted polymer (NIP). Moreover, the IIP exhibited excellent recyclability after six adsorption-desorption cycles.
