In this study， quantitative analysis of multi-components with single marker(QAMS) was established and validated to simultaneously determine four sesquiterpenoids(β-eudesmol， atractylon， atractylolideⅠ， atractylolide Ⅱ) in Atractylodis Rhizome based on the gas chromatographic method(GC). Using β-eudesmol as the contrast， the relative correctionfactors(RCF) of the other three sesquiterpenoids were determined by GC. Within the line arranges，the values of RCF of β-eudesmol to atractylon， atractylolideⅠand atractylolide Ⅱ were 0.823， 0.690 and 0.766， respectively. The RCF had a good reproducibility in various instruments， chromatographic columns. According to their RCF， we simultaneously determined four sesquiterpenoids in Atractylodis Rhizome only using one marker. The results of QAMS method were validated by comparing with that of internal standard method， and no obvious significant difference was found.

OBJECTIVETo establish an RP-HPLC method for determination of atractylodinol in Ateractylodes lancea and compare the contents of atractylodinol in the herbs of different origins.

METHODThe samples were separated on an Agilent TC-C18 (4.6 mm x 250 mm, 5 microm) column with the mobile phase of acetonitrile-water (49:51). Flow rate was 1.0 mL x min(-1). The detection wave length was set at 337 nm. Column temperature was 30 degrees C.

RESULTThe linear range of atractylodinol was 9.12 x 10(-2) -9.12 mg x L(-1) (r = 0.999 9), the average recovery was 97.15%, RSD was 1.5% (n = 5). The contents of atractylodinol were in the range of 0.268-1.213 mg x g(-1) in the samples from different orgins. The contents of atractylodinol in samples growing in Dabieshan mountain were higher than those in Jiangsu province (P < 0.001).

CONCLUSIONThe established method for determination of atractylodinol is accurate and reliable, which can be used to evaluate the quality of A. lancea, the contents of atractylodinol in the sample was related with its morphological characteristic and geographic orgin.

To establish a fingerprint spectrum for Atractylodis Macrocephalae Rhizoma stir-fried with wheat bran based on UFLC/Q-TOF-MS, and make a principal component analysis (PCA) with Markview software, in order to compare the changes of components between raw and processed Atractylodis Macrocephalae Rhizoma with raw wheat bran as the blank. The results showed that the changed in components raw Atractylodis Macrocephalae Rhizoma and Atractylodis Macrocephalae Rhizoma stir-fried with wheat bran were apparently observed by PCA. Six compounds were identified to have significant changes in mass fraction before and after being stir-fried, namely atractylenolide-I, atractylenolide-II, atractylenolide-III, atractylentrid, atractylon and an unknown compound. Among them, atractylenolide-I and atractylenolide-II generated from dehydration and dehydrogenation of atractylenolide-III may be the material base of Atractylodis Macrocephalae Rhizoma stir-fried with wheat bran for strengthening spleen.

Through study on the correlation between Atractylodis macrocephala lactones ingredient content and topographic factors, we researched regionalization from topography of five main producing provinces of the country, in order to provide a scientific basis for A. macrocephala reasonable cultivation. By sampling from 40 origins of five main producing provinces of the country, the variation of A. macrocephala lactones ingredient content in different conditions of topographic factors and the effect of altitude, slope and aspect was analyzed by SPSS. Then according to the relationship between A. macrocephala lactones ingredient content and topographic factors, the ecological suitability regionalization was conducted by using ArcGIS based on topographic factors. It is suitable for growth of A. macrocephala in the hilly and mountainous areas of southern whose A. macrocephala lactones ingredient content is in high levels. It is unsuitable for growth of A. macrocephala in Northern plain areas, but we can cultivate A. macrocephala in the hilly and mountainous areas of Northern. The most suitable topographic condition for cultivation of A. macrocephala : altitude 200 meters above, slope 3.00-4.99 degrees.

This study established the fingerprint and combined it with chemical pattern recognition to evaluate the quality of Atractylodes chinensis samples from different producing areas and then employed the quantitative analysis of multi-components by single marker(QAMS) method to verify the feasibility and applicability of the established method in the quality evaluation of A. chinensis. The fingerprints of A. chinensis samples were constructed via high performance liquid chromatography(HPLC) to evaluate the inter-batch consistency. With the quality control component atractylodin as the internal reference, the relative correction factors(RCFs) were established for atractylenolide Ⅰ, atractylenolide Ⅲ, and β-eudesmol and the content of the four components was calculated. The external standard method was used to verify the accuracy of QAMS method. The quality of A. chinensis was further evaluated by similarity analysis, clustering analysis, and principal component analysis. The fingerprints of 13 batches of samples were calibrated with 21 common peaks, and 4 common peaks were identified with the similarities all above 0.9. The RCFs established with atractylodin as the internal reference represented good reproducibility under different experimental conditions. Specifically, the RCFs of atractylenolide Ⅰ, atractylenolide Ⅲ, and β-eudesmol in A. chinensis were 2.091, 4.253, and 6.010, respectively. QAMS and ESM showed no significant difference in the results, indicating that the QAMS method established in this study was stable and reliable. Thus, HPLC fingerprint combined with QAMS can be used for the quality evaluation of A. chinensis, providing a basis for comprehensive and rapid quality evaluation of A. chinensis.

A method of comprehensive chemical pattern recognition of Atractylodis Rhizoma was established by GC-MS fingerprint, principal component analysis, cluster analysis and discriminant analysis. A DB-wax column (0.25 mm x 60 m, 0.25 microm) with El ion source and 70 V electron multiplier were used for GC-MS analysis. Using principal component analysis, cluster analysis, and discriminant analysis, 15 common peaks of sample fingerprints for chemical pattern recognition research were analysed. The same results were obtained from the fingerprint, principal component analysis and cluster analysis, which could use to distinguish genuine Atractylodes lancea, ungenuine A. lancea and A. chinensis. Thus, this method could be used for the quality control and comprehensive evaluation of Atractylodis Rhizoma.
