[Determination of the eliminating ratio of TCM polysaccharide to hydroxyl radical by kinetic fluorescent spectrophotometry].

Objective: To explore reaction dynamic of hydroxyl radical (*OH) and salicylic acid,and to determine the elimination ratios of TCM polysaccharide to *OH by kinetic fluorescent analysis.

Methods: The impact dynamics factors of this reaction were studied by fluorescent, such as the reaction of concentration, reaction time and temperature. The dynamical equation was built, a kinetic fluorescent spectrophotometry based on the reaction was developed to determine the elimination ratio.

[Analysis on the volatile oil of Xinhui Pericarpium Citri Reticulatae in different years by GC/MS].

Objective: To analyze the difference of the volatile oil of Xinhui Pericarpium Citri Reticulatae in different years.

Methods: The components and contents of the volatile oil of Xinhui Pericarpium Citri Reticulatae were analyzed in different years by GC/MS.

Results: The components and contents of the volatile oil of Xinhui Pericarpium Citri Reticulatae changed along with the years.

Dual fluorescence/contactless conductivity detection for microfluidic chip.

A new dual detection system for microchip is reported. Both fluorescence detector (FD) and contactless conductivity detector (CCD) were combined together and integrated on a microfluidic chip. They shared a common detection position and responded simultaneously.
