Rice hulls and bagasse waste agricultural products, China has rich resources. Bagasse, rice hulls, and contains a variety of active substances with physiological functions, including the high economic value of pharmaceutical active ingredients of ferulic acid, such as the depth of the development of its value greatly improved. However, due to the lack of rapid detection of rice hulls and bagasse means and ferulic acid extraction method, the rice hulls and bagasse can not be fully exploited. In order to better take advantage of these two waste from extraction and separation of ferulic acid effective method has great significance. This study is the following four aspects: 1. According to the nature of ferulic acid, for the determination of ferulic acid in bagasse High Performance Capillary Electrophoresis (HPCE) method. Of the buffer solution of pH and ionic strength and other factors were studied, and ferulic acid HPCE Analytical conditions: capillary column of uncoated fused silica capillary column (length 50cm, inner diameter of 75um, from the detection window: 40cm); buffer solution 50mmol · L-1 borax solution, pH value of 8.6; separation voltage 25kV; column temperature was 25 ℃. Under these conditions, ferulic acid concentration 0.08g · L-1-2.4g · L-1 range a good linear relationship, R = 0.9995, the method for sample handling easy. The recoveries of up to 98.6%. (2) using orthogonal design optimization rice hulls alkaline extraction of ferulic acid, determined by examining the concentration of NaOH, extraction temperature and extraction time of three factors, three levels of testing, analysis of variance obtained after extraction conditions are: temperature 55 ℃, 2% NaOH concentration, extraction time 6h, 100g rice hulls can be extracted from about 150mg ferulic acid. Established to detect rice hulls of ferulic acid by high performance liquid chromatography (HPLC) method with acetonitrile -1% acetic acid solution as the mobile phase gradient elution method, the column temperature 30 ℃, flow rate of 0.8mL · min- one of the conditions, the rice husk extract ferulic acid separation and determination of results are as follows: ferulic acid concentration in 1.760X10-3g · L-1-2.200 X10-2g · L-1 range a good linear relationship, R = 0.9976, recovery of 93.0%. 3 by ferulic acid in the molecular structure with the phenolic hydroxyl and carboxyl groups to form tri-n-octylamine molecular hydrogen bonding principle, a liquid membrane emulsion containing mobile carrier system, respectively, for separation and enrichment bagasse and rice husk extract ferulic acid. Studied Span-80 and the mass concentration of tri-n-octylamine, Foreign Minister HCl and sodium phosphate internal phase concentration on the rate of migration of ferulic acid, and the optimal conditions: the membrane phase consists of 5% TCA, 8 % Span-80 and the membrane solvent, kerosene, inner aqueous phase containing 0.16mol · L-1 sodium phosphate solution, the external phase containing 0.024 mol · L-1HCl solution, and the inner membrane phase compared to 1:1, the speed at 2500rpm Milk produced under the emulsion was 1.2:2 compared with the outer, low-speed stirring 10min. Under these conditions, the mobility of ferulic acid in water up to 99.0%. The emulsion liquid membrane system using sugarcane bagasse ferulic acid enrichment, enrichment factor 2.1, the separation factor 1.6. The emulsion liquid membrane system for rice hulls ferulic acid enrichment, enrichment factor 2.0, the separation factor 3.6. These parameters show that compared with ferulic acid enriched bagasse, rice hulls enrichment of the system of ferulic acid is better. 4 ferulic acid at different pH conditions, the formation of two kinds of ions and molecules shaped body. According to their solubility in water and organic phases of different sizes, to establish a non-liquid membrane emulsion carrier system to Span-80 is a surface-active agent, a film enhancer liquid paraffin, sodium phosphate as the internal phase. The effects of Span-80 and liquid paraffin concentration, the Foreign Secretary HCl and internal phase sodium concentration and other factors, resulting enrichment conditions: membrane phase containing 5% Span-80, 3% liquid paraffin and kerosene solvent membrane, inner phase of 0.08mol · L-1 sodium phosphate solution, the Foreign Secretary was 0.1mol · L-1HCl solution, and the inner membrane phase compared to 1:1.2, at a speed of 2000rpm prepared milk, lotions and outside compared to 1:2, stirring speed 20min. Under these conditions, the mobility of ferulic acid in water up to 99.0%. The emulsion liquid membrane system using bagasse enriched from ferulic acid, enrichment factor 2.5, the separation factor 6.6. The system for rice hulls ferulic acid enrichment, enrichment factor 3.2, the separation factor 10.4. These parameters indicate that the system is not only enriched rice hulls ability of ferulic acid in enriched bagasse of ferulic acid, and strong ability to eliminate interference.
