The building of 2.6 Chromatographic Fingerprints
2.6.1 the calculating of relative retention time α
Select appearance time it is relatively placed in the middle, in each sample existing component as reference peak (α=1).Find out sample institute
There is the relative retention time at peak are as follows: tRi/tRα, tR in formulaiFor the appearance time of each component, tRαFor the appearance time referring to peak.
2.6.2 referring to the selection at peak
Compared by chromatogram, choosing the 3rd strong peak (No. 3 peaks) in chromatogram is to calculate the opposite of each peak referring to peak
Retention time α.
2.6.3 the foundation and evaluation of characteristic spectrum
Take the dried immature fruit of citron orange of 10 batch different sources with Rhizoma Atractylodis Macrocephalae respectively by legal system available test sample solution below " 2.3 " item, then
By condition sample introduction under " 2.1 " item and record chromatogram.The characteristics of according to 10 batches of sample characteristic spectrums, can determine 5 peak conducts
Common characteristic peaks, and four peaks therein have been demarcated, No. 1 peak is aurantiamarin peak, and No. 2 peaks are synephrine peak, and No. 3 peaks are Rhizoma Atractylodis Macrocephalae
The peak lactone II I, No. 4 peaks are the peak atractylodes lactone I, these three peak separating degrees are preferable, and retention time is suitable for, therefore can be used as reference
Peak, chromatogram are shown in Fig. 1.The characteristic spectrum signal of each batch of Fructus Aurantii Immaturus is imported into " the Chinese medicine that exploitation is presided over by Chinese Pharmacopoeia Commission
Fingerprint similarity evaluation software (2009 editions) ", the common pattern of 10 batches of medicinal material characteristic spectrums is shown in Figure 11.Calculate comparative diagram
Similarity data between spectrum and 10 batches of sample maps, similarity calculation the results are shown in Table 4.Similarity thinks to meet 0.90 or more
It is required that.As a result, it has been found that the similarity of 10 batches of medicinal materials shows that this experimental method is reliably effective 0.90 or more.
The measurement of 2.7 test sample characteristic spectrums
The dried immature fruit of citron orange processed products of Rhizoma Atractylodis Macrocephalae for taking 10 batches to be prepared by the dried immature fruit of citron orange, the Rhizoma Atractylodis Macrocephalae of different sources, is prepared by test solution
Method operation, precision draw the measurement of 10 μ L sample introductions, obtain each sample HPLC characteristic spectrum.The dried immature fruit of citron orange Rhizoma Atractylodis Macrocephalae of 10 batch different sources
Medicine materical crude slice retention time and peak area and relative retention time the results are shown in Table 2, table 3, table 4.Chromatogram is shown in Figure 11.
2 10 batch different sources dried immature fruit of citron orange atractylodes slice characteristic spectrum retention time of table
