Abstract: In the paper, the best extraction technology of nasal mucosa dosing bromo gels is preferably selected. Orthogonal test is applied to screen the best technological condition for extracting nasal mucosa dosing bromo gels with content of ferulic acid and gastrodin as the indexes; it is figured out that the best technological condition is ethanol; the optimal technology is stable and feasible and can raise content of ferulic acid remarkably.

Abstract: Objective: The determination and ratio of ferulic acid and gastrodin in Xiongma Decoction extract by different extraction process were compared, to provide scientific research basis on creating new drugs, controlling the quality combination of modern Compound Chinese, determining the main effect and compatibility. Methods: Chuanxiong and Tianma were extracted by different extraction method such as the boiling method and ethanol extraction by different concentrations to make ​​Xiongma Decoction. The content of ferulic acid and gastrodin were determination by HPLC to make Xiongma Decoction and their ratio was calculated. Chromatographic conditions of ferulic acid: mobile phase: methanol-0.01 % acetic acid solution (30:70, V/V), the detection wavelength: 310nm; chromatographic conditions of Gastrodin: mobile phase: acetonitrile-0.05 % phosphoric acid (3:97, V/V), detection wavelength: 220nm. Results: The determination of ferulic acid was 0.976mg • ml-1, gastrodin was 1.586mg • ml-1, the ratio of ferulic acid and gastrodin was1:1.6 in boiling method; while the determination of ferulic acid was 6.08mg • ml-1, gastrodin was 3.57mg • ml-1, the ratio was 1.7:1 in ethanol extraction. Conclusion: There are different determination and ratio, when there is different extraction process in the same prescription. This may bring about changes the main effect in prescription. This suggests that the ratio of the main active ingredient should be included in the quality inspection, when preparation process of the traditional recipe was changed.

Abstract: High performance capillary zone electrophoresis (HPCE) was used in this text to determine the content of ferulic acid in a ready-made Chinese herbal medicine called AI-FUNUAN-GONG (in pills). Electrophoretic separation conditions: Uncoated fused silica capillary column (75um×49/58cm), injection height 7.5cm, 30mmolL-1 borax solution, separation voltage 20kV, injection time 10s, detection wavelength 315 nm, experimental temperature 20°C.Linearity was kept in the concentration ranging from 1~62.5 mg·L-1 of ferulic acid with correlation coefficient of 0.970. The average recovery was 97.541% and RSD value was 6.57%. Sample content of ferulic acid was 0.0715mg/g. This method has the advantages of strong specificity, simpleness, speediness, accurate results and good repeatability in separation and it is useful for determination of ferulic Acid in AI-FU-NUAN-GONG Pills.

Abstract: The effect of ferulic acid (FA) and oxidized ferulic acid (OFA) on performances of the soybean protein-isolate/chitosan composite films was evaluated. The FA and OFA showed an excellent compatibility and miscibility of in the composite films, and leaded the surface more compact and smooth. The FA and OFA also enhanced the thermal stability of the composite films. The FA and OFA enhanced the performance of the composite films by raising the band energy of the crosslinked molecules.

Abstract: The effect of modification with transglutaminase (TGase) and 4-hydroxy-3-methoxycinnamic acid (ferulic acid) on properties of tilapia skin gelatin film (TSGF) was researched. The results showed that the peroxide inhibition of modified TSGF increased from 14.7% to 62.0% and 52.1%, when concentrations of TGase and ferulic acid were 0.20 or 1.0 mg·mL-1. At the same time, the WVP coefficients were lower about 24.2% and 20.6%, respectively. The solubility of TSGF decreased with the increase in concentration of TGase and ferulic acid. As the formation of hydrogen bonds in the structure of the film, the amide A band was shifted towards higher wave numbers after modification.

Abstract: A kind of nonwoven containing ferulic acid is prepared by electrospinning method. It was observed that the diameter of the fiber was about 200 nm by SEM. The antibacterial activities against Escherichia coli and S. aureus were also investigated. The result showed the nonwoven prepared was effective against Escherichia coli, and S. aureus. Furthermore, Fabric UV transmittance test and air permeability were taken. It was found that the nonwoven achieved good UV protection and air permeability.

Abstract: The effect of FA and OFA on performances of the soybean protein-isolate/chitosan composite films was evaluated. The FA and OFA enhanced the tensile strength and thermal stability of the composite films significantly, while they reduced the water vapor permeability to 60.3 % and 72.8 % of the control respectively. Moreover, the OFA was more effective to enhance the tensile strength of the composite films than the FA.

Abstract: An Electrohydrodynamic atomization (EHDA) process was exploited to prepare ferulic acid (FA)-loaded shellac microparticles. SEM observations showed that all the particles were round and solid with their sizes gradually increased from 0.68 ± 0.21 to 2.75 ± 0.64 μm as the concentrations of shellac and FA in ethanol raised from 20% to 50% (w/v). Wide-angle X-ray diffraction analyses demonstrated that FA had been totally converted into an amorphous state in the shellac matrix microparticles. Attenuated total reflectance Fourier transform infrared analysis disclosed that the hydrogen bonding presented between FA and shellac molecules. In vitro dissolution tests verified that all the microparticles were able to provide a fine sustained drug release profile. The release time periods had a close relationship with the diameters of microparticles. All the microparticles released the loaded FA via a typical Fickian diffusion mechanism. The present study provides an easy way to develop novel drug delivery microparticles for providing sustained drug release profiles.

Abstract: Chuanxiong, as a medicinal plant, has been demonstrated useful for the treatment of cardio-cerebrovascular diseases in China. The physicochemical characterization of Chuanxiong particles was greatly influenced by ultrafine pulverization. To study the physicochemical characterization of Chuanxiong, the raw plant material of Chuanxiong was ground to 6 μm particles by HSCS (High Speed Centrifugal Sheering) pulverizer. The micron particles were characterized by optical microscope and SEM. Ferulic acid is one of active ingredients of Chuanxiong, and its extraction yield was determined to evaluate the chemical characterization of Chuanxiong powder. Ferulic acid was analyzed by HPLC (High Performance Liquid Chromatography). The results showed that after ultrafine pulverization, the plant cell walls were broken into pieces and the extraction yield of ferulic acid was increased by 7.739% compared with the normal particles.
