使纯化

Take the 10~12ml single-valve capacity as the example, with flings turns the head to separate evenly, 36.000rpm 60 the hour, turns the head with the angle type to separate 45, OOOrpm 36 the hour, the former including adds the deceleration to use in common 130,000,000 revolution of actuation department lives, the latter must use 100,000,000 revolution of actuation department lives, this was 100 ~ 20,000,000,000 transfers to at that time the supercentrifuge total life looked, without doubt each time tests the expense to be excessively high, in addition the CsCl amount used are many, price expensive and so on factors, causes this kind of separation purification work to become the very expensive experiment.

以10~12ml单管容量为例，用甩平转头分离，36.000rpm 60小时，用角式转头分离45，OOOrpm 36小时，前者包括加减速在内共用去1.3亿转驱动部寿命，后者也要用去1亿转驱动部寿命，这对当时超速离心机总寿命为100~200亿转来看，无疑每次实验费用过高，加上CsCl用量多、价格贵等因素，使这类分离纯化工作成为非常昂贵的实验。

Essential oils from the dried rhizomes of zingiber officinale were extracted by supercritical-CO2 fluid(SFE-CO2 ),the flavonoids of essential oils were further extracted by solvent.

ResultsWith polyamide resin to absorb and purify, eluted with 40%,60%,70%,80% ethanol, good results were obtained.

结果通过聚酰胺树脂富集与纯化，并采用40%，60%，70%，80%乙醇梯度洗脱，可以使芦荟蒽醌衍生物得到较好的分离。

There is still no effective method on effectively curing this disease. In this paper, egg-yolk antibody against WSSV was prepared and its effectiveness on preventing and curing this disease was tested. In order to get adequate WSSV antigen, the differential-speed centrifugation and the sucrose gradient ultracentrifugation were used to isolate and purify WSSV from the foregut and gill tissues of shrimps affected with WSSV.

为了获得足量的WSSV抗原，本文以感染WSSV的对虾前肠和鳃等组织为材料，分别利用差速离心法和蔗糖密度梯度离心法进行了WSSV的分离纯化，结果表明：利用差速离心法虽然能够使所分离的WSSV的完好率达70﹪左右，但其中杂质较多，病毒粒子的收获量较少；利用蔗糖密度梯度离心法提取WSSV，虽然其完好率稍低于差速离心法，但也可以达到60%以上，并且，所得到的WSSV的量要大大高于差速离心法，适合于WSSV的大量分离。

It took several years to develop an industrial purification process that removed contaminants such as PCBs (polychlorinated bi-phenyls), pesticides, cholesterol, polyunsaturated fatty acids, and vitamins A and D from the shark liver oil, while at the same time concentrating the alkylglycerols without destroying them.
