Methods The nereistoxin toxins were extraceted with ethyl acetate∶cyclohenane(1∶1),cleaned by the aluminite powder online and then by auto gel permeation chromatography.

方法取一定量的Al2O3放入萃取池中做吸附剂，通过快速溶剂萃取仪萃取血液中杀参毒素类农药，同时达到在线净化的效果，后运用凝胶色谱净化联用仪进一步净化浓缩到2ml，提取液经LC/MS/MS进行检验。

Take the mature evening primrose seed as raw material extraction evening primrose oil, through the optimized craft, the determination influence factor, returns to parents' home by the 510nm wave length extinction value determination oxidation inhibitor and the emulsifier sees the star anise oil the oxidation influence.

以成熟的月见草籽为原料提取月见草油，通过优化工艺、确定影响因素，以510nm波长的吸光度值测定抗氧化剂和乳化剂对月见草油的氧化的影响。

The main component consists of natural hamamelis extract, snow lotus, angelica, aconite, safflower, red peony root, Chinese waxgurd seed, gingko fluid, chamomile extract, lipin balance fluid, astrictive etc a variety of vegetal extracts.

主要成份天然金缕梅提取液、雪莲、白芷、白附子、红花、赤勺、冬瓜仁、银杏液、甘菊精华、油脂平衡液、收敛剂等多种植物萃取精华。

By identifying the obtained components by TLC, three alkaloids components were detected, among which one was nuciferine. The other two were N-Nornucirerine and O- Nornucirerine, identified by Nuclear Magnetic Resonance and Mass Spectrum.6、In order to exploit natural bacteriostat of lotus leaves, optimal extraction process and antibacterial characteristics were studied.

两者得到的化合物分别经TLC鉴别，得到3个生物碱成分，其中1个为荷叶碱，其余两个应用核磁共振和质谱等技术鉴定为N-去甲荷叶碱和0-去甲荷叶碱。6、从荷叶天然食品抑菌剂开发的角度，研究了荷叶抑菌有效成分的提取优化工艺及抑菌特性。

Antibacterial experiments results showed that extractions of bacteriostat of lotus leaves had significant antibacterial activities, and the antibacterial characteristics were stable, slightly affected by environment Conditions, such as pH value, temperature, concentration of cations. Also, the extractions exhibited strong antibacterial activities very soon.

抑菌试验结果表明，荷叶抑菌有效成分提取液具有较强的抑菌活性，且抑(来源：ABe064C论文网www.abclunwen.com)菌性能稳定，受环境条件，如pH值、温度、金属离子浓度等变化影响较小，且较短的作用时间就表现出较强的抑菌作用，因此，荷叶天然食品抑菌剂的开发具有很好的应用前景。

Examples of humectants include lactic acid, urea (the urea found in creams is synthetically produced by combining one molecule of carbon dioxide with two molecules of ammonia and not obtained from urine), hyaluronic acid (able to retain 1000 times its weight of water), propylene glycol, glycerin, sorbitol, gelatin, lecithin, sodium pyrrolidone carboxylic acid, and butylene glycol.

常见的湿润剂有乳酸，尿素（面霜里的尿素来自于二氧化碳和氨分子的合成而不是从尿中提取的），透明质酸（能保持自身成分1000倍的水分），丙二醇，丙三醇，山梨糖醇，明胶，卵磷脂，吡咯钠，羧基酸和丁二醇。

METHODS:The serum was added with VC as antioxidant and treated with ethyl acetate to extract rifampiein. The method employed C18 column,and CH3OH-0.025mol/L NaA c(adjust to pH 7.0 with HAc)as mobile phase,chlordiazepoxide as intra-standard,a nd the UV detection wave length was at 334nm.

血清加抗氧剂维生素C后，用乙酸乙酯提取浓集进样，采用C18柱(150×3.9mm 4μ)，以甲醇-0.025mol/L NaAc(用HAc调到pH 7.0)(62∶40)为流动相，氯氮( HT6"，5"K〗艹)/为内标，紫外检测波长为334nm。
