     2.2 The Process of inclusion volatile oil

     2.2.1 volatile oil β CD inclusion complex

    Preparation of saturated solution method [3], taking β CD

    plus saturated aqueous solution made from distilled water, and placing 250 ml triangular flask, in the specified temperature, in a certain mixing speed, precision dropping a certain amount of volatile oil: ethanol (1:1) solution, stirring inclusion specified time, take out, home refrigerator (4 ?) to place 24

    h, leaching, with a small amount of anhydrous ethanol wash three times, vacuum dried solids 60 ? to constant weight, was

    inclusion.

     2.2.2 Volatile oil inclusion Optimization of process conditions based on test results reported in the literature and pre-determined inclusion volatile oil of the main factors are: volatile oil β CD ratio of inclusion time,

    inclusion temperatures; 3 for each factor in determining the level of , using L9 (34) orthogonal to the yield of volatile oil revenues and the inclusion rate for the evaluation of indicators for inclusion technology of optimization, the

    weights were 0.4 and 0.6. Factors in Table 4. Orthogonal experimental results shown in Table 5, analysis of variance results in table 6. Table 4 Volatile Oil β CD inclusion

    factor level table (a little) Table 5 Volatile Oil β CD

    inclusion of the orthogonal experimental results (omitted)

     Table 6 volatile oil β CD inclusion analysis of

    variance (abbreviated)

     Actual results of the orthogonal direct analysis and variance analysis shows that volatile oil β CD and the

    inclusion of the proportion of time on the experimental results are very significant impact of inclusion temperature

    had no significant effect, affecting the degree of A> B> C. Optimum inclusion process is A2B2C1, the volatile oil and β

     CD of the feed ratio of 1:6, inclusion time was 3 h, inclusion temperature at room temperature. 3 copies of essential oil obtained by optimizing the best technology of a verification experiment, the results of inclusion volatile oil

    from an average rate of 86.1%, 75.6% yield of inclusion complex, indicating that this process is stable.

     2.3 β CD Identification of volatile oil inclusion

     2.3.1 TLC [4]

     Sample Preparation: Take volatile oil 0.15 g buy 100 ml

    flask, add petroleum ether to the scale, as a test product for the solution of A (positive control); taking β CD

    inclusion volatile oil finished 0.15 g, plus petroleum ether wash, filter Guo, petroleum ether filtrate added to the fixed volume 100 ml, as a solution for the test product B; taking β

     CD inclusion volatile oil plus 95% ethanol was extracted 30 min, filtration, the filtrate constant volume of ethanol added to 100 ml, as a test items for the solution C; taking β

     CD 1 g, plus 95% ethanol was extracted 30 min, filtration, the filtrate constant volume of ethanol added to 100 ml, as a solution for the test product D (negative control).

     TLC: lessons of the above-mentioned four kinds of

    solution, 5 μl, points in the same piece of silicon G CMC

     Na thin, and with petroleum ether ethyl acetate (17:3)

    as the agent, started out, dried spray dinitrophenylhydrazine test solution, view, test products for the solution in the A, C chromatography, in the corresponding position, substantially

    the same color of the spots shows that, after inclusion mention made of the volatile oil components has not changed, The test items for the B, D (negative sample) chromatography in the absence of such spots, indicating β CD volatile

    oil from the formation of inclusion complexes has been very good. The results shown in Figure 1.

     2.3.2 Identification of UV spectra [5] basically the same sample preparation TLC. Using UV spectrophotometry, scanning range of 200 ~ 400 nm, to absorb the absorption peak position

    of the curve to determine the formation of inclusion complexes, in the results shown in Figure 2 ~ 5. Figure 2

    shows UV spectra of volatile oil, 284 min are characteristic absorption peaks. Figure 3 for inclusion re-distilled volatile

    oil obtained UV spectrum, maintaining a characteristic absorption spectral features, indicating a result of volatile oil package and the ingredients do not change; Figure 4 UV spectrum for the inclusion, 284 min without the characteristic absorption peak Note the formation of inclusion complexes of molecular very good; Figure 5 for the β CD distillation of

    the negative control.

     3 Discussion

     By Cyperus rotundus and cinnamon essential oil extracted from the optimum study found that water increases the amount

    of volatile oil extraction had no significant effects, while the extraction time and soaking time has a significant impact. This may be due to the root bark of Cyperus rotundus and cinnamon is a class medicine, require a long soak, the moisture can soak into the dense organization of plant cells, so that slipped out of the volatile oil with the water vapor.

     By TLC and UV identification, we can see Cyperus rotundus, cinnamon essential oil inclusion complex of volatile oil no longer has the original and UV spectral characteristics of thin spots. Note the formation of inclusion complexes of molecular very good. Inclusion complex recovered by distillation of the volatile oil TLC and UV characteristics of the original volatile oil similar to prove that the process of

    inclusion volatile oil preserve quality.

     Compound consumption by the Central Plains pain capsule production process will be volatile oil spray before loading the capsule particles, volatile oil components poor stability, reduce the effect. After the process is made through the inclusion loaded capsules, so that the stability and efficacy of agents have increased.
