ABSTRACT
Objective: To study the chemical constituents in the barks and leaves of Cinnamomum cassia.Methods: The crude extracts of the barks and leaves of Cinnamomum cassia were extracted by ethanol, the chemical constituents of the crude extracts were separated and purified by chromatographic methods and identified by spectroscopic analysis.Results: Five lignans were separated from the barks and two lignans were separated from the leaves of Cinnamomum cassia as follows: (7S,8R)-dihydrodehydrodiconiferyl alcohol 9'-O-β-D-apiofuranosyl-(1→6)-O-β-D-glucopyranoside (1), 1,2,3-propanetriol,1--3-methoxyphenyl-(1R,2R) (2), (6R,7R,8R)-7a-lyoniresinol (3), (6S,7R,8R)-7a-lyoniresinol (4), (6R,7S,8S)-7a-lyoniresinol (5),(+)-lariciresinol(6), (-)-4-epi-lyoniresinol (7).Conclusion: All the lignans are isolated from Cinnamomum cassia for the first time.
ABSTRACT
Objective:To simultaneously separate 5 phenylpropanoids from Cinnamomum cassia by semi-preparative HPLC, and explore their immunosuppressive activity. Methods:After extracted by ethanol, the ethyl acetate part of Cinnamomum cassia was isola-ted by semi-preparative HPLC. The separation was conducted on an Ultimate XB-C18 (250 mm × 10 mm, 5μm) semi-preparative chro-matographic column and the mobile phase was acetonitrile-water with gradient elution. The detection wavelength was 330 nm, and the flow rate was 2. 5 ml·min-1 . The sample volume was 0. 3 ml. MS and NMR spectroscopic analysis were used to determine the config-urations. A CCK-8 method was used to detect the immunosuppressive activity of phenylpropanoids. Results: Totally 5 phenylpro-panoids were separated from Cinnamomum cassia by the semi-preparative HPLC, and identified as erythro-guaiacylglycerol, (7R,8S)-syringoylglycerol, (7S,8S)-syringoylglycerol, 3-methoxyphenyl-acrylaldehyde and O-methoxy cinnamaldehyde. The inhibitory rates of T cells and B cells of the compound 3 was more than 20% at the concentration of 800μmol·L-1 . Conclusion:The method is conven-ient with good separation effect, which can simultaneously separate 5 phenylpropanoids from Cinnamomum cassia, and among them, the compound 3 shows immunosuppressive effect to some extent.
ABSTRACT
To investigate the anti-inflammatory, analgesia and antipyretic effects of Chaige Qingre granules. Meth-ods:Kunming mice were used to make auricle swelling model by dimthylphenanthrene, and the auricle swelling degree was measured to test the anti-inflammatory effect of Chaige Qingre granules. Mice were used to make pain models by acetic acid, and the body twis-ting of the mice was counted to observe the analgesia effect of the granules. The fever model in rats was induced by yeast, and the body temperature of the rats was measured to investigate the antipyretic effects of the granules. Results:Chaige Qingre granules could relieve the auricle swelling degree significantly, and the inhibition rate was 46. 3% in the high dose group. High and middle dose groups could reduce the body twisting frequency with the inhibition rate of 51. 1% and 61. 8%, respectively. Every Chaige Qingre granules group could lower the body temperature after one hour of the administration, and the temperature could be reduced 0. 56 degrees Celsius in the high dose group. Conclusion:Chaige Qingre granules can effectively inhibit auricle swelling degree, relieve pain and reduce heat.
ABSTRACT
OBJECTIVE: To establish a HPLC method for the simultaneously determination of Vitamin D2, Vitamin A and Vitamin E in Cernevit-12 for injection. METHODS: An Inertsil(ODS-2) C18 column was selected as separation column at 30℃. The mobile phase consisted of acetonitrile-methanol-methylene chloride (80∶10∶10) at a flow rate of 1.0mL?min-1. The detection wavelength was set at 265nm and the injection volume was 10?L. RESULTS: The linear ranges of Vitamin D2, Vitamin E acetic ester and Vitamin A palmitate were 0.61～1.43?g?mL-1, 222.6～519.4?g?mL-1 and 1.21～2.82mg?mL-1 respectively. The average recoveries were 99.79%, 99.53% and 101.63%, with RSD of 1.66%, 0.184 6%, 0.113 4%. CONCLUSION: The method is simple, rapid and accurate, and suitable for the determination of Cernevit-12.
ABSTRACT
OBJECTIVE:To study the pharmacokinetics and serum fingerprints of Decoction for Puerperal Blood Stasis at different time.METHODS:The content of Ferulaic acid(FA) was determined by HPLC.The pharmacokinetic study was carried out.The active constituent in the Decoction for Puerperal Blood Stasis was analyzed based on the serum fingerprints of FA.RESULTS:The distribution and metabolism of FA in rabbits after oral administration of Decoction for Puerperal Blood Stasis assummed two compartment model.The fingerprints between serum at different time and blank serum showed significant differences.CONCLUSION:The content change of FA monitored with serum fingerprints was in line with the rule of pharmacokinetics of FA in Decoction for Puerperal Blood Stasis.The fingerprints can be applied to clarify the pharmacokinetic characteristics,the pharmacological action and the action mechanism of Decoction for Puerperal Blood Stasis.
