[ ABSTRACT] AIM:To investigate the effects of Chaihu Shugan powder ( CSP) on lipid metabolism and the pro-teins involved in adenosine 5’-monophosphate-activated protein kinase (AMPK)/sirtuin 1 (SIRT1) pathway in the liver tissues of the rats with non-alcoholic fatty liver disease (NAFLD).METHODS: Sprague-Dawley rats were randomly di-vided into normal control ( NC) group, with HFD ( HFD) group and CSP group.The NAFLD models were established by feeding with HFD for 16 weeks in the rats.The rats in CSP group were intragastrically administered with CSP extracts (9.6 g· kg-1 · d-1 ) , and blood and liver samples were collected 16 weeks later.Serum and liver levels of total cholesterol ( TC) and triglyceride ( TG) , and serum levels of alanine aminotransferase ( ALT) and aspartate aminotransferase ( AST) were measured using an automatic biochemical analyzer.The histological changes of liver tissues were observed with HE staining, while the lipid deposition was observed with Oil Red O staining.The ultrastructural changes of the liver tissues were observed under transmission electron microscope.Moreover, the protein levels of AMPK, phosphorylated AMPK (pAMPK), SIRT1 and uncoupling protein 2 (UCP2) in the liver were detected by Western blot.RESULTS:The results of HE staining, Oil Red O staining and electron microscopy demonstrated that NAFLD rat model was successfully estab-lished.Compared with NC group, the serum and liver levels of TC and TG, and serum level of AST in model group were markedly elevated ( P<0.01) .Moreover, the protein levels of pAMPK and SIRT1 in HFD group were markedly reduced (P<0.01), whereas UCP2 level was elevated (P<0.01).Furthermore, liver levels of TC and TG, and serum level of AST in GSP group were markedly reduced as compared with HFD group ( P<0.05 ) .The protein levels of pAMPK and SIRT1 were elevated ( P<0.05 ) , whereas the UCP2 level was reduced as compared with HFD group ( P<0.01 ) .The protein level of AMPK between the 3 groups had no significant difference.CONCLUSION: CSP attenuates hepatic lipid disorder and hepatic lipid deposition in NAFLD rats induced by feeding with HFD for 16 weeks, which is associated with the activation of AMPK/SIRT1 pathway.

OBJECTIVE：To analysis the correlation between chrom aticity value and quality index of Atractylodis chinensis decoction piece powder stir-fired with bran ，and to determine its processing time. METHODS ：The processed samples of 16 batches of A. chinensis decoction piece stir-fired with bran （S0-S15，S0 is the raw product of A. chinensis ）were prepared ，and chromaticity values of all samples were determined ，such as lightness value （L*），yellow blue value （b*），red green value （a*）. UPLC fingerprint of sample were analyzed ，and the contents of extract and volatile oil were also determined. Pearson correlation was used to analyze the correlation between the chromaticity value and quality index （relative peak area of each chromatographic peak in UPLC fingerprint ，water-soluble extract content ，alcohol-soluble extract content and volatile oil content ）. Multivariate statistical analysis （principal component analysis ，cluster analysis ，partial least squares discriminant analysis ）was carried out with chromaticity value and quality index ，and the processing time of A. chinensis decoction piece stir-fired with bran was determined by grey correlation method. RESULTS ：In the process of bran frying ，with the extension of processing time ，L* and b* of decoction pieces powder decreased ，and a* increased first and then decreased ；relative areas of peak 1 and peak 2 increased first and then decreased，while relative areas of peak 3（5-hydroxymethyl furfural ）increased，and the areas of the other peaks decreased. The content of the extract did not change significantly with time ，and the content of the volatile oil decreased. The results of correlation analysis showed that the relative peak area of peak 2-27，alcohol-soluble extract content and volatile oil content had a certain correlation with the chromaticity value ，while the relative peak area of peak 1 and water-soluble extract content had no linear correlation with the chromaticity value. Results of multivariate statistical analysis showed that the samples were divided into mild （S0-S5），excessive （S12-S15），moderate （S6-processing time of 18-33 min）. The results of grey correlation method showed that the processing time of A. chinensis decoction piece stir-fired w ith bran should be controlled in the range of 18-24 min，and the optimal processing time was 18 min. CONCLUSIONS ：There is a correlation between chromaticity value of A. chinensis decoction piece powder stir-fired with bran and the relative peak area of 27 chromatographic peaks ，and content of extract and volatile oil. It is suggested that the processing time should be 18 min.

OBJECTIVE：To establish the UPLC fingerprint of Polygonum cuspidatum ，and to determine the contents of four active ingredients and to provide reference for the quality evaluation of P. cuspidatum . METHODS ：The determination was performed on Waters BEH C 18 column（100 mm×2.1 mm，1.7 μm）with mobile phase consisted of acetonitrile- 0.2％ formic acid （gradient elution ）at flow rate of 0.4 mL/min. The column temperature was 40 ℃，and detection wavelength was 290 nm. The sample size was 1 μL. The fingerprints were evaluated by similarity calculation，cluster analysis and orthogonal partial least square discriminant analysis （OPLS-DA）. Using polydatin as internal standard ，relative calibration factors of resveratrol ，emodin-8-O- β-D-glucoside and emodin were determined to develop a method of QAMS. The contents of 4 above components in 15 batches of P. cuspidatum were calculated by relative calibration factors. The results of QAMS were compared with those of external standard. RESULTS：UPLC fingerprints of 15 batches of P. cuspidatum were established ，and 12 common peaks were confirmed. Five components were identified ，i.e. polydatin ，resveratrol，emodin-8-O-β-D-glucoside，emodin，emodin methyl ether. The fingerprint similarity of 15 batches of P. cuspidatum was in the range of 0.865-0.976. According to cluster analysis ，15 batches of P. cuspidatum were classified into 4 categories，showing certain regularity of origin. Seven markers were identified by OPLS-DA method. The order of difference significance was peak 7＞emodin-8-O-β-D-glucoside＞resveratrol＞peak 8＞polydatin＞peak 1＞ peak 10. The relative deviation among the contents of resveratrol ，emodin-8-O-β-D-glucoside and emodin in 15 batches of P. cuspidatum determined by QAMS and external standard method was less than 5.0％，indicating that there was no significant difference between the two methods. CONCLUSIONS ：UPLC fingerprint combined with QAMS method is convenient and reliable for the quality evaluation of P. cuspidatum ；the quality of P. cuspidatum produced in Chongqing and Anhui province is better.

OBJECTIVE：To compare the chemical components in Sinapis alba before and after stir-frying. METHODS ： UPLC-Q-Exactive Obitrap MS was adopted to analyze chemical constituents of S. alba before and after stir-frying. The determination was performed on Waters CORTECS T 3 column with mobile phase consisted of methanol- 0.1％ formic acid solution （gradient elution ）at the flow rate of 0.25 mL/min. The column temperature was 30 ℃ and the sample size was 2 μL. High resolution MS adopted heating electrospray electron source ，positive ion scanning mode ，scanning range m/z 120-1 000. The chemical constituents of S. alba before and after stir-frying were identified by Compound Discover 3.2 software combined with relevant database ，and the content changes of chemical constituents were analyzed by using peak area. Chemometrics analysis was performed for the content changes of chemical constituents using peak area as variable. RESULTS ：A total of 54 chemical components were identified in S. alba ，mainly fatty acids （represented by erucic acid ），alkaloids（represented by sinapine ）， flavonoids. After stir-frying ，the contents of 19 chemical components changed significantly ，of which the contents of 10 components decreased significantly and those of 9 components increased significantly （P＜0.05）. Principal component analysis and orthogonal partial least squares discriminant analysis could clearly distinguish S. alba from stir-fried S. alba . CONCLUSIONS ：The contents of some chemical components of S. alba change significantly after stir-frying ，which may be one of the important reasons for the change of efficacy after stir-frying.
