Herba ephedrae was saturated with 0 . 5 % hydrochloric acid , the extract was extracted with ether and chloroform respectively , from which ephedrine was separated and purified by column chromatography 以0 . 5 %盐酸浸泡麻黄草，分别用乙醚、氯仿萃取麻黄粗提物，通过柱色谱法分离提纯麻黄碱。
Housefly larvae had developed humoral immunus and chemical defensense system . antimicrobial substances were extracted from the skin of housefly larvae , pupae and the remains of the larvae feed 从家蝇幼虫体表中提取其分泌的具有抗菌活性物质，经洗脱、透析及脱色得粗提物，为白色粉末状物质。
The paper studied the stability of microencapsulated lycopene under different conditions , such as time , light , temperature , microwave , and compared stability with pure and coarse extraction of lycopene 摘要研究了番茄红素微胶囊在不同时间、光、热及微波条件的稳定性，并与番茄红素纯提物和粗提物进行稳定性对照实验。
Capsaicinoid was purified from the extracted capsicum by activated carbon , and the total amounts of three capsaicinoid components was quantitatively determined by rp - hplc . the purity of capsaicinoid is 97 . 2 % 摘要使用活性炭纯化辣椒碱粗提物， rp - hplc定量测定辣椒素样品中主要成分。在优化条件下得到辣椒素提取物纯度为97 . 2 % 。
The results showed that using the simple device , the reaction was finished in shorter time with higher rates and when it was used 95 % alcohol as picking up solvent , the percent of crude extractings from ginkgo biloba leaves was the highest 结果表明，简易装置所用时间较短、收率较高且操作简单方便；利用95 %乙醇作为提取剂在使用简易装置时，银杏叶粗提物得率最高。
Using agarose gel double diffusion method , the antiserum of pea ferritin can cross - react with the crude extraction of soybean seed ferritin . the result indicated that high specific antiserum had been acquired and could be used ~ in the detection of the expressi 5 、植物铁蛋白的免疫学检测琼脂糖免疫双相扩散法显示，制备的豌豆铁蛋白抗血清可与大豆铁蛋白粗提物发生免疫交叉反应。
The antimicrobial secretion could be divided into three sections , every section had antimicrobial activity . the first could be extracted by petroleum ether , the second could be extracted by ethyl alcohol , the third could dissove in water and could be separated by sephadex g - 50 , g200 gel filtration chromatography and carbornmethyl cellulose - 1 anion - exchange chromatography and detected by a256 , . the antimicrobial secretion had wide spectrum and had strong inhitory activity against germs and fungi , they could inhibit sixteen kinds of plant pathogenic germs , eight kinds of animal germs and eight kinds of plant pathogenic fungi 粗提物经石油醚萃取可得第一个活性部分，剩余部分经无水乙醇萃取可得第二个活性部分，剩余物质再经凝胶sephadexg - 50后有两个峰，第二峰有活性，再经凝胶sephadexg - 200后有三峰，第二峰有活性，将其经过阳离子交换柱cm - 1后有两峰，此两峰均有抑菌活性。
The xerocomus spadiceus lectin , xsl , was isolated from extracts of fruiting bodies of the mushroom xerocomus spadiceus using a procedure that involved ( nh4 ) 2so4 precipitation , anion exchange chromatography on deae - cellulose , affinity chromatography on affi - gel blue gel , cation exchange chromatography on cm - cellulose , and gel filtration by fast protein liquid chromatography on superdex 75 从砖红绒盖牛肝菌( xerocomusspadiceus )子实体粗提物中，经过deae -纤维素阴离子交换层析、 affi - gelbluegel亲和层析、 cm -纤维素阳离子交换层析和superdex75fplc凝胶过滤，纯化了砖红绒盖牛肝菌凝集素。
