Objective:To establish the quality evaluation method of Perillae caulis formula granules based on the three kind of quality indexes of standard decoction. Methods:Eighteen batches of Perillae caulis were collected from different habitats according to different technical requirements, eighteen batches of standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The content of Caffeic acid and Rosmarinic acid were determined and calculated by Ultra High Performance Liquid Chromatography (UPLC). Then the fingerprints of standard decoction of and formula granules of Perillae caulis were established by UPLC . The similarity values of fingerprints between formula granules and standard decoction were calculated. Results:The average paste-forming rate of standard decoction was (7.16±1.97)%. The paste-forming rates of three batches of formula granules were 5.52%, 5.25% and 5.34%, respectively. The average content of Caffeic acid and Rosmarinic acid in standard decoction was (12.06±3.37)mg/g. The contents of three batches of formula granules were 5.52, 5.82, 5.77 mg/g, respectively. Seven common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, three of which were identified as Caffeic acid, N-Feruloyl Octopus amine and Rosmarinic acid by comparison of reference substance. The fingerprints similarity of Perillae caulis dispensing granules and standard decoction were 1.000, 0.995 and 0.997, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method can provide basis for the establishment of quality standard of Perillae caulis dispensing granules.

OBJECTIVE：To compare the c hemical components differences of Inula japonica before and after honey-frying. METHODS：UPLC-MS/MS method was adopted. The determination was performed on Waters ACQUITY UPLC BEH C 18 column with mobile phase consisted of 0.1％ formic acid-acetonitrile （gradient elution ）at the flow rate of 0.3 mL/min. The column temperature was set at 30 ℃，and sample size was 5 µL. The electrospray ion source was scanned by positive ion mode. The first order mass spectrometry scanning range was m/z 70-1 050，the second order mass spectrometry scanning range was m/z 50-1 050， and the normalized collision energy was 40，60 eV ；mass spectrum type was the peak figure ，the flow rate of sheath gas was 35 arb，the auxiliary airflow speed was 10 arb，the spray voltage was 3.80 kV，the S-lens voltage was 50 V，the heating temperature was 350 ℃，and the capillary temperature was 350 ℃. The components were identified by Qual Browser 4.1.39.1 software， referring to the online high-resolution database mzCloud and local database OTCML of high-resolution mass spectrometry of TCM ， and combined with relevant literature. The principal component analysis （PCA）and orthogonal partial least squared-discriminant analysis（OPLS-DA）of I. japonica before and after honey-fried were performed by using SIMCA 14.1 statistical software ，and variable importance projection （VIP）value greater than 1 was used as the standard to screen the differential components before and after honey-frying.

The results of PCA showed that I. japonica and honey-fried I. japonica were located on both sides of the score diagram respectively. The results of OPLS-DA showed that the VIP values of 7 components were greater than 1，which were peak 19（britanin），peak 6（quercetagitrin），peak 1（1-caffeoylquinic acid ），peak 21（vitexicarpin），peak 20（tomentosin）， peak 13（spinacetin）and peak 3（daphnetin）. CONCLUSIONS ：After honey-fried ，the content of chemical components of I. japonica changed and decreased to a certain extent. Britanin ，quercetagitrin，1-caffeoylquinic acid ，tomentosin，vitexicarpin， spinacetin and daphnetin may be the differential components of I. japonica and honey-fried I. japonica .

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.
