Temat postu: UGG boots Italia Supercritical Fluid Extraction an
Supercritical Fluid Extraction and Determination of six should be pills in the content of borneol and eugenol
Spectrum of conditions to the above column temperature 90 ℃, other things being equal,

, this time to achieve the baseline separation of the two. The results were: isoborneol 43.52%. RsD = 0.67%, n = 3, borneol 54.85%, RSD = 0.39%. n = 3. 3.4 SFE extracted samples: fine, said after smashing through 100 mesh sieve set extract 100mg medicine pool, according to the best extraction conditions for operation, with the amount of ethyl acetate and absorbed,

, ultrasonic extraction 60rain, <military medicine) t999 No. 9 No. 3, after 33 cooling accurate internal standard solution 0.5ml, ethyl acetate volume to 10Hll volumetric flask (extract 2) . Soxhlet Extraction: Fine said, the above powder 0. 5g, 50ml Soxhlet extractor set, add ethyl acetate and 75ml, water bath extraction 6h, filtered in l00Hll volumetric flasks, washed with ethanol residue, precision check internal standard 5ml, ethyl acetate added to the scale backup (extract 3). Preparation of standard curve: standard solution aliquot in l0Hll 0.1,0.2,0.4,0.8,1.2 ml flask, internal standard solution into 0.5ml, diluted to the scale, the gas chromatography. The peak area ratio (Y) on the content (X) for the regression, the regression equation: Y = 2.115X borneol a 9.928 × 10. . , R = 0.9999. Eugenol Y = 2.153X +1.526 × 10 a, r = 0.9999 linear range of 52.2-626.4ng and 48.7-584.4ng. Determination: direct injection extract l l, extract 2, extract three more serious due to impurity, are purified alumina sample after sample 1, the results in Table 3. Table 3 the results of different extraction methods for determination of n = 3) SFE of sample recovery test: add the herbs in the quantitative standard solution 0.8ml, dry, measured in the same way, the measured recovery rate, borneol 101.93% ( RSD: 1.56%, / 1 = 3), eugenol 98.43% (RSD = 2.26%, n = 3). 3.5 Conclusion SFE borneol and eugenol in the extraction, the extraction efficiency was significantly higher than traditional solvent extraction, SFE is simple, quick, the whole process takes only ten minutes; co2 inexpensive, and non-toxic, non-flammable, chemically inert, volatile; In addition, SFE has a good selectivity, interference in the chromatographic process fewer impurities, the sample can be directly extracted without sample pretreatment, saving a lot of time and energy, SFE quality control of traditional Chinese medicine has a broad application.
