Objective: To establish an identification for Xingqizhitong Pills Methods: The microscopical identification and TLC were used. Results: Semen strychni, Radix aucklandiae, Flos carthami, Fructus chebulae, Lignum aquilariae resinatum could be detected out by TLC. Also Gypsum fibrosum and Resina liquidambaris were identified by physical and chemical identification. Conclusion:The experimental method is simple, reproducible and accurate.

This study was aimed to isolate and characterize of chemical constituents in a traditional Mongolian medicine HERBA CLEMATIS. Normal and reverse phase coloumn chromatography, gel filtration chromatography sephadex LH-20, and preparative HPLC were used for isolation and purification compounds from the water extraction of the arial part ofC. aethusaefoliaTurcz. The planar structures and spatial configurations of isolated compounds were identified by high resolution MS, 1D and 2D NMR, and other spectrographic methods. The chemical research on the Mongolian medicine results 6 compounds, dihydrodehydrodiconiferyl alcohol (1), syringaresinol (2), pinoresinol (3), epi-pinoresinol (4), lirioresinol B dimethyl ether (5) and loliolide (6). All the compounds were isolated from this plant for the first time.

OBJECTIVE To conduc t qualitative and quantitative analysis for the chemical compounds in 3 species of wild Veratrum（V. nigrum ，V. maackii ，V. dahuricum ）from Inner Mongolia. METHODS HPLC-Q-Exactive-MS/MS technology was used to identify the chemical components of V. nigrum ，V. maackii and V. dahuricum by consulting SciFinder ，ChemSpider database and related literatures and comparing with the reference substance. The contents of polydatin ，oxyresveratrol and resveratrol in 3 species of wild Veratrum were determined by HPLC. RESULTS A total of 31 compounds were identified ，including 13 stilbenes， 11 flavonoids，4 organic acids ，2 glycosides，1 brasilin. Most of the compounds were shared by 2 or 3 species of wild Veratrum， only 2 flavonoids kaempferol and luteolin were owned by V. dahuricum . The total contents of polydatin ，oxyresveratrol and resveratrol in 3 species of wild Veratrum were in the range of 6.618-11.292 mg/g，and the total contents of them in V. nigrum were the highest ，followed by V. maackii and V. dahuricum . The contents of polydatin and resveratrol in V. maackii were the highest ，and the content of oxyresveratrol in V. nigrum was highest. CONCLUSIONS Most of the components of 3 species of wild Veratrum are similar，only kaempferol and luteolin are unique to V. dahuricum . The contents of polydatin ，oxyresveratrol and resveratrol are significantly different among 3 species of wild Veratrum.

OBJECTIVE： To prepare Ganshen granules， formulate its quality standards primarily and establish its HPLC fingerprint. METHODS： Using feeding speed， roller speed， roller pressure and roller clearance as factor， grain forming rate as index， single factor test and orthogonal test were used to optimize the granulation technology of Ganshen granules. According to 2015 edition of Chinese Pharmacopeia （part Ⅳ） （shorted for pharmacopeia）， moisture， granulation and dissolution were determined. TLC was used for the qualitative identification of Lycium barbarum， Astragalus membranaceus， Codonopsis pilosula in the Ganshen granules. HPLC method was used to determine the contents of betaine， calycosin-7-glucoside and lobetyolin in Ganshen granules. Fingerprints of 10 batches of Ganshen granules were drawn. RESULTS： The optimal dry granulation technology of Ganshen granules included that 25 r/min feeding speed， 8 r/min roller speed， 7 MPa roller pressure and 1.1 mm roller clearance， The grain forming rate is 85.83％. The moisture， granulation and solubility of Ganshen granule were all in line with pharmacopeia standard. TLC of L. barbarum， A. membranaceus and C. pilosula showed the same color spots on the corresponding positions of the reference chromatogram. The linear range of sample mass of betaine is 4.32-8.64 μg， and the linear range of mass concentration of calycosin-7-glucoside and lobetyolin were 5-30 and 10-60 μg/mL， respectively. RSDs of precision， reproducibility and stability tests （24 h） were all lower than 2.0％ （n＝5）. Average recoveries were 97.02％， 99.25％ and 101.04％ （all RSD＜1.7％， n＝6 or n＝9）. The contents of them were 4.298、0.054、0.025 mg/g， respectively. The similarity of HPLC fingerprints of 10 batches of Ganshen granules to control fingerprint was higher than 0.95. CONCLUSIONS： The optimal granulation technology of Ganshen granule is stable and feasible， and established quality standard and HPLC fingerprint can provide reference for quality control of Ganshen granule.
