Gas chromatographic analysis of a propanil plus oxadiazon formulated mixture;

Under the high pressure mercury lamp,the photodegradation of oxadiazon in different solvents was studied.

A method was introduced for the determination ofoxadiazon technical by gas chromatography on SE-30+OV-210 using triphenyl phosphate as internal standard.

Separating licorice flavonoids from glycyrrhiza by HP-20 macroporous resin is studied.

Licorice flavonoids mainly include flavonoids, isoflavones, flavonols, chalcones, flavanones, dihydrochalcones.

Objective To study the preventive effect of licorice flavonoids(LF)on hyperglycemia and hyperlipemia of experimental diabetic rats induced by feeding high-fat and high-sugar diet combined with low-dose streptozotocin(STZ) injection,and to elucidate its possible pharmacological mechanisms.

Determination of metamitron residue in cereal and oil using poly (3-thiophenemalonic acid) modified glassy carbon electrode

Herbicide metamitron (Ⅰ) was synthesized by three steps reaction.

This compound was an important intermediate to synthesize carfentrazone-ethyl, one super highly effective herbicide.

Interaction Between Metribuzin and Deoxyribonucleic Acid;

GC-MS analysis of metribuzin technical and its main impurities;

Voltammetric Behaviors of Metribuzin at a Glassy Carbon Electrode and Its Practical Application;

Results showed that acetamiprid as pesticide was extremely toxic to Daphnia magna,highly toxic to Brachydanio rerio and low toxic to Scenedesmus obliquus;pymetrozine as pesticide was low toxic to Daphnia magna and Brachydanio rerio,but moderately toxic to Scenedesmus obliquus;oxadiazon as herbicide is high.

An efficient method with microchemical method and solid phase extraction (SPE) technique for the determination of oxadiazon residues in cereals by gas chromatography-mass spectrometry (GC-MS) has been established.

The properties,uses and market demands of the oxadiazon products are reviewed in this paper.
