Embodiment 2
The preparation of standard liquid:
Prepared using methanol and contain campesterol, stigmasterol and cupreol hybrid standard storing solution, after nitrogen evaporator dries up, Prepared respectively with acetonitrile again containing the μ g/mL of campesterol 2.5,5,10,20,40,50, stigmasterol and cupreol 5,10,20,40, 80th, 100 μ g/mL standard serial solution.
High-efficient liquid phase chromatogram condition is:
Chromatographic column:WaterC18 posts (4.6mm × 250mm, 5 μm)
Detector:Waters2489 ultraviolet-visible detectors
Detection wavelength:208nm
Column temperature:30℃
Mobile phase:Acetonitrile:Water=94:6(v/v)
Flow phase velocity:1.0mL/min
Sample size is 20 μ L
The measure of the rate of recovery and precision:
Homogeneous campesterol sample is taken, is divided into 3 groups, it is molten to be separately added into the horizontal hybrid standard series of 3 various concentrations Liquid (campesterol:10、20、40μg/mL;Stigmasterol and cupreol:20th, 40,80 μ g/mL) form high, normal, basic 3 mark-on groups And 1 blank control group, replication 3 times, calculate the rate of recovery.
Fetch high, normal, basic 3 mark-on groups in yield experiment and repeat sample introduction 5 times interior on the same day, calculate withinday precision, Sample introduction is repeated in continuous 3d daily 3 times, calculate day to day precision, represented with RSD.
As can be seen here, embodiment 1 is better, and detection time is short, and precision is high, and the rate of recovery is high, and RSD values are relatively It is low.
It is noted that at this end during invention, due to campesterol on C-22 positions more than stigmasterol one it is double Key, campesterol polarity is slightly weaker than stigmasterol, therefore be more easy to be eluted out by non-polar solven, but because stigmasterol is in C-24 Position methyl more than campesterol, therefore both can polarization neutralizing effect.Due to less polarity between the two Difference, campesterol and stigmasterol often produce co-elute phenomenon, and the chromatographic condition of most of document report uses methanol Or first alcohol and water is simultaneously bad as mobile phase, its separating effect to both, it is difficult to reaches baseline separation.Due to molten in reversed-phase column The eluting power of agent weakens with the enhancing of sample polarity, and the polarity of methanol is better than acetonitrile, therefore uses the stronger second of eluting power Nitrile is more conducive to the separation of stigmasterol and campesterol.But use 100% acetonitrile its polarity is relative to methanol as mobile phase Decrease, make stigmasterol and campesterol can not be completely isolated when being separated in HPLC, so increase a certain proportion of water, increase Add the polarity of mobile phase, so that stigmasterol and campesterol can reach baseline separation.In addition, the ratio of addition water should be strict Control, if otherwise not under the proportioning, is just unable to reach the baseline separation of sterol monomer, stigmasterol and campesterol chromatographic peak meeting It is inseparable.Also, we invents is tested by Optimization of mobile phase, acetonitrile and the water isocratic elution under certain proportion proportioning are found, 3 kinds of sterol monomers is reached baseline separation, and retention time was substantially reduced to 35min from 2 hours, it is final to determine Optimal chromatographic condition is 1.0mL/min, Detection wavelength 208nm, 35 DEG C of column temperature, and this method precision and average recovery are equal It is higher, it disclosure satisfy that the testing requirements of 3 kinds of sterol content of monomer of accurate quantitative analysis.
As can be seen here, our invention not only makes 3 kinds of sterol monomers reach baseline separation, substantially reduces retention time, most It is 1.0mL/min, Detection wavelength 208nm, 35 DEG C of column temperature, and this method precision and sample-adding that optimal chromatographic condition is determined eventually The rate of recovery is higher, disclosure satisfy that the testing requirements of 3 kinds of sterol content of monomer of accurate quantitative analysis.
It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferable The present invention is described in detail embodiment, it will be understood by those within the art that, can be to the technology of the present invention Scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solution of the present invention, it all should cover in this hair Among bright right.
