A biocomposite material (1) and methods of production thereof are described. The biocomposite material (1) exhibits a physical stiffness, strength and toughness comparable to known glass fibre composites while its composition makes it inherently impermeable to water. A general formulation for the biocomposite material (1) is given by the expression: Cel(1-x-y)HPIx HPOy where “Cel” represents cellulose fragments (2), “HPI” represents hydrophilic binders (4), “HPO” represents hydrophobic binders (5) and (x) and (y) quantify the percentage by weight of the hydrophilic (4) and hydrophobic binders (5) present within a material, respectively. The described properties of the biocomposite material (1) are achieved when (x) is within the range of from 0.05 to 0.55 and (y) is within the range of from 0.05 to 0.65.

The invention relates to a method for extracting CEL I nuclease in celery and discards measures adopting a plurality of high-speed or ultra-speed centrifugation and a plurality of gel filtration and ion exchange chromatography in the prior art. The method comprises the following steps: adding a small amount of sodium sulfite to extract so as to reduce and clear colored substances in the extract; adopting a thermal denaturation physical method to rapidly clear a great amount of foreign protein with poor temperature toleration; utilizing the characteristic that CEL I is the combination of glycoprotein and activated concanavalin to combine CEL I nuclease and concanavalin so as to remove the foreign protein and further purify the CEL I; and finally, selecting DEAE-Sepharose FF as a suitable medium for the CEL I by once chromatography purification. Accordingly, the extraction method replaces the time-consuming and expensive measures adopting a plurality of high-speed even ultra-speed refrigerated centrifugation, a plurality of gel filtration and ion exchange chromatography, and the like and achieves the aims that the CEL I nuclease is rapidly extracted from the celery and purified.

The invention discloses a method for detecting advanced glycation end products (AGEs) in main stream smoke of a cigarette. The method specifically comprises analysis and determination of carboxy methyl lysine (CML) and carboxyethyl lysine (CEL). The method comprises the following steps: trapping total particulate matter of cigarette smoke by virtue of a Cambridge filter; carrying out ultrasonic extraction on the filter with a hydrochloric acid solution; and carrying out analysis by combining a cation exchange solid-phase extraction column purification method with liquid chromatogram-tandem mass spectrometry (LC-MS / MS). The method has the characteristics that (1) a detection method for AGEs in the main stream smoke of the cigarette is built for the first time; (2) a sample pretreatment method is built according to the characteristics of cigarette smoke sample matrix, derivative reaction is not required, and the pretreatment is simple and efficient; and (3) the method is high in sensitivity, good in qualitative accuracy and suitable for analysis of large batches of samples.
