Description

A kind of novel magnetic nano material and its application in An Naigelieting drug tests
Technical field
The invention belongs to material and Pharmaceutical Analysis field, and in particular to a kind of novel magnetic nano material and its in An Naige Arrange the application in the drug test of spit of fland.
Background technology
Because the drug concentration in the drug concentration in organism, especially serum is directly related to drug effect.Therefore, from facing For in terms of bed application and Drug safety assessment, it is necessary to set up a kind of simple, sensitive, accurate detection biological fluid and medicine The analysis method of An Naigelieting contents in thing.There are high performance liquid chromatography, thin layer with extensive Pharmaceutical Analysis method at present Chromatography, ion-exchange chromatography etc..Current few document reports on An Naigelieting content assaying methods, and use purple The report that outside-visible spectrophotometry determines An Naigelieting contents there is no.
In Pharmaceutical Analysis, the separation and concentration for sample is that the pre-treatment of sample plays critical effect.Separation is rich Collection is so that analysans is separated from its matrix, extracted, while reaching the purpose of concentration medicine, is carried so as to realize High accuracy, the effect of sensitivity.With the development and progress in epoch, current separation and concentration technology has obtained very big development. Conventional method for separating and concentrating has extraction, including liquid-liquid extraction (LLE), SPE (SPE), solid phase micro-extraction technique (SPME), liquid-phase micro extraction technique (LPME), dispersive liquid-liquid microextraction technology (DLLME) etc..Surveyed to biological fluid Regularly, because complicated component in body fluid, it is not readily separated to form interference, and medicament contg to be determined is general all very low, so sample The separation and concentration of product seems increasingly important.Take reasonable efficient separation and concentration technology by the medicine to be measured of low content from complicated Separation and Extraction comes out in biological substrate, for fast and accurately carrying out quantitative analysis, is the important content of internal Pharmaceutical Analysis. In view of the advantage and disadvantage of various isolation technics, have very big improvement, such as Magnetic solid phases extraction skill for solid phase extraction techniques at present Art.The solid phase extraction (SPE) grown up earliest is called Solid extraction column method, be from early 1970s grow up one Plant sample separation and concentration technology.And Magnetic solid phases extraction be based on SPE and grow up it is a kind of new, environment-friendly Sample pre-treatments analytical technology, utilizes the suction-operated more efficiently extractive analysis thing of magnetic Nano material.Magnetic Nano material Because combining the dual characteristicses of magnetic responsiveness and nano-particle, so the adsorbent that can be extracted as Magnetic solid phases.With it is traditional Sample Pretreatment Technique Used such as solid phase extraction, solvent extraction, ultrasonic extraction etc. compared, and Magnetic solid phases extraction is used in The process of sample pre-treatments is largely simplified, and easily realizes the separation of phase.
Magnetic carrier technology (MCT) is reported by Robinson et al. first.In 1973, micro- (or nanometer) magnetic carrier Synthesis has caused extensive interest.MCT unique and noticeable characteristic is that magnetic nanoparticle can be by applying Easily separated from sample solution external magnetic field.These particles are superparamagnetism, it means that they can be easy Ground is attracted to a magnet, but it is on the scene be removed after can not keep magnetic.The characteristic causes them to be particularly suitable for use in sample preparation, because For that compared with non magnetic adsorbent, need not centrifuge after the extraction or filtered sample.

In this experiment, An Naigelieting tablets are determined with working curve method, are as a result 101.5mg/ pieces, with There was no significant difference for labelled amount 100mg/ pieces.
The degree of accuracy and the rate of recovery
The method tested in this experiment using mark-on determines the rate of recovery, and have rated the degree of accuracy of method.Relative recovery It is calculated as follows:
C in formulareal、Cadded、CfoundIt is the An Naigelieting concentration determined in actual sample respectively, is added in sample An Naigelieting concentration of standard solution, An Naigelieting concentration in the sample determined after standard items is added.Measuring result As shown in table 2.The rate of recovery is 96.8%~102.3% in medicine, and the rate of recovery is 96.8%~100.9%, explanation in human serum The accuracy of method is preferable, the measure available for An Naigelieting contents in medicine.
The rate of recovery of table 2 is tested
It can be seen that, the method that the present invention detects An Naigelieting concentration in sample using ultraviolet-uisible spectrophotometer is accurate Degree is high, favorable reproducibility, and testing result is credible in embodiment 8.
