抽提

The present invention relates to a process for rapid solution synthesis of a peptide, the process comprising repetitive cycles of steps-: a coupling step, using an excess of an activated carboxylic component to acylate an amino component, a quenching step in which a scavenger is used to remove residual activated carboxylic functions, wherein the scavenger may also be used for deprotection of the growing peptide, one or more aqueous extractions and optionally, a separate deprotection step, followed by one or more aqueous extractions, characterised in that the process comprises at least one step, referred to as step, in which an amine or a thiol comprising a free anion or a latent anion is used as a scavenger of residual activated carboxylic functions.

Results showed that:there were significant differences in the carbon to oxygen ratioamong various positions and processingconditions;lignin and abstracts mainly made up the surface of bamboo;high temperature drying resulted in the decomposition of volatile abstracts in the surface,whichindicated some structure of cellulose and hemicellulose,while the effects of processing with boracic acid were not apparent;the bamboo processed in hightemperature and with boracic acid showed decreasedfree hydroxide and activity at the same time;the amount of active free hydroxide of inner layer was higher thanthat of the outer.

结果表明：不同部位和不同处理条件下竹材表面的碳氧比有很大差异；竹材表面主要以木素和各种抽提物为主；高温干燥导致竹材表面易挥发的抽提物分解，使部分纤维素和半纤维素的结构特征得以显露，而硼酸处理效果不明显；高温处理和硼酸处理后竹材表面的自由羟基减少，活性降低；竹黄表面的活性自由羟基的数量高于竹青表面。

It was difficult to extract corn pigments completely, for some of them were in a protein-bind state. It was better to use active carbon for the decolorization of GEON, the conditions were 40℃, stir time 6 hours, the ratio of carbon to hydrolyzate 1: 100 , but as to milk-like powder, it was better to extract pigments after spray drying.

最后，本文对玉米黄素的可抽提性也进行了初步研究，结果表明，部分色素与蛋白质结合而难以抽提，因而有机溶剂难以将色素抽提完全，对Gln活性肽营养液而言，可选用酶解后加活性炭进行脱色，脱色条件为40℃，搅拌6小时，炭液比为1∶100；而对黄粉蛋白乳粉而言，喷雾干燥后用乙酸乙酯脱色，可使酶解干燥后黄粉的异味减轻。

The genomic DNA of Nosema bombycis was isolated from it's spores, using two methods, ie, Alkaline-Germination and Liquid-nitrogen.

分别用碱发芽法及液氮法抽提了家蚕微孢子虫基因组DNA，其中碱发芽法抽提的DNA质量及数量上好于液氮法抽提的DNA。

In order to overcome the negative effects, the extractives of the fresh E. camaldulensis shavings, which were obtained by using the sorbitic-, freezing-, laser plasma- and supersonic-extracting approaches, were analyzed by ZETA and SIZER to find out the leaching rule of micro and nano particles in E.

采用单因素试验法，分析赤桉溶出粒子的特征，探索赤桉木材纳米粒子在索氏抽提、超声波抽提、冷冻抽提、激光等离子抽提中的溶出规律。

Their half lives were 27.29 and 69.16 days respectively. Monocrotophos degraded into both methanol extractable and unextractable residues in the submerged soil.The analysis of 14C-methanol extractable. residue by TLC and ARG indicated that degraded products of monocrotophos were triether phosphate,;N-de-methyl Azodrin, O, O-dimethyl-vinyl-phosphatc,O-demethyl Azodrin,and O, C-demethyl Azodrin.The principal degraded extratable product of monocrotophos was triether phosphate, which incresed from 5% of the parent solution of monocrotophos to a range of 28-83%, furthermore and its degradation process was much faster in the unterilized soil than in the sterilized soil.

久效磷在淹水土壤中降解为甲醇可抽提态和不可抽提态残留物，对甲醇可抽提态残留物经TLC和红外光谱分析表明，其降解物为磷酸三酯、N-去甲基久效磷、O，O-二甲基乙烯基磷酸酯，0-去甲基久效磷，以及O，C-去甲基久效磷，但主要为磷酸三酯，其含量由母液中的5％增加到28—83％，这种降解过程，在未灭菌土壤中比在灭菌土壤中快。

These yeast extracts may simply be labeled as 'Autolyzed Yeast Extracts' or as 'Yeast Extracts'.

这些酵母抽提物一般被简单标注为&自溶酵母抽提物&或&酵母抽提物&
