Studies on the chemical constituents in herbs of ethanolic extract from herbs of Dicliptera chinensis / 中国中药杂志

<p><b>OBJECTIVE</b>To study the chemical constituents of ethanolic extract from herbs of Dicliptera chinensis.</p><p><b>METHOD</b>The compounds were separated by silica gel column chromatography, preparation TLC and reverse phase HPLC, their structures were identified by the spectroscopic methods of UV, NMR and MS.</p><p><b>RESULT</b>Seven compounds were isolated from ethyl acetate extract. Their structure were identified as octasulphur (1), secoisolariciresinol dimethyl ether diacetate (2), 5-methoxy-4, 4'-di-O-methyl secolariciresinol (3), chinensinaphthol methyl ester (4), loliolide (5), beta-sitosterol 3-O-beta-D-glucopyranoside (6) and stigmasterol 3-O-beta-D-glucopyranoside (7).</p><p><b>CONCLUSION</b>All the compounds except 6 were obtained from the plants of Dicliptera for the first time.</p>

Studies on anti-inflammatory and immunologic enhancement of kangning granules / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the effect of Kangning granules on inflammatory and immunology.</p><p><b>METHOD</b>Pedal swelling induced by 1% agar in mice, dermal capillary hyper-permeability induced by histamine in rats were used to evaluate the anti-inflammatory of Kangning granules, and the clearance rate of intravenous charcoal particles was used to study its effect on non-specific immunologic functions. Serum haemolysin level and the number of antibody secretory cells in spleen were determined to assess its effects of specific immunologic functions. MTT colored method was used to determine the effect of Kangning granules on T- or B-Lymphocytes proliferation.</p><p><b>RESULT</b>5, 10, 20 g x kg(-1) of Kangning Granules significantly inhibited pedal swelling induced by agar in mice (P < 0.05, P < 0.01). 2.4, 4.8, 9.6 g x kg(-1) of Kangning Granules evidently decreased dermal capillary hyper-permeability induced by histamine in rats (P < 0.05, P < 0.01). 10, 20 g x kg(-1) of Kangning Granules enhanced the phagocytic function and phagocytosing velocity in mice (P < 0.05). 5, 10, 20 g x kg(-1) of Kangning Granules obviously increased serum haemolysin level and the number of antibody secretory cells in spleen (P < 0.05, P < 0.01). 20 g x kg(-1) of Kangning Granules promoted B-Lymphocytes proliferation (P < 0.05).</p><p><b>CONCLUSION</b>Kangning granules significantly inhibited inflammatory reaction and increase immune functions in animals.</p>

Determination of protopine and isocorydine in root of Dactylicapnos scandens by HPLC / 中国中药杂志

<p><b>OBJECTIVE</b>To establish a HPLC method for determination of protopine and isocorydine in root of Dactylicapnos scandens.</p><p><b>METHOD</b>The separation was performed in a PHENOMENEX-C18 column with a mobile phase of methanol-0.2% phosphoric acid (adjusted to pH 7.0 with triethylamine)(50:50), The detection wavelength was at 254 nm and the flow rate was 0.8 mL x min(-1).</p><p><b>RESULT</b>The average recovery of Protopine and Isocorydine was 97.9%, 98.6% respectively, and RSD 1.3%, 1.4%.</p><p><b>CONCLUSION</b>This method is accurate, simple and reliable. It can be used for quality control of D. scandens.</p>

Pharmacognostical studies on Dactylicapnos scandens / 中国中药杂志

<p><b>OBJECTIVE</b>To offer evidences for quality control of medicinal plant of Dactylicapnos scandens.</p><p><b>METHOD</b>Pharmacognostic studies were carried out through field collection, morphological and microscopic characteristics, and TLC.</p><p><b>RESULT</b>Observation and description of the experimentation were made.</p><p><b>CONCLUSION</b>Dactylicapnos scandens can be identified from Genus of Dactylicapnos which has the similar morphological characteristics. The morphological and microscopic characteristics and the results of TLC can be used as evidences for quality control of this medicinal plant.</p>

Lipid compounds from Echinacea purpurea / 中国中药杂志

<p><b>OBJECTIVE</b>To study the lipid constituents from Echinacea purpurea.</p><p><b>METHOD</b>The compounds were isolated by chromatography method and the structures were identified on the basis of spectral analyses.</p><p><b>RESULT</b>Five compounds were isolated and identified as, 1 beta, 6 alpha-dihydroxy-4(14)-eudesmene(1), (2E, 4E, 8Z, 10E)-N-isobutyl-2,4,8,10-dodecatetraenamide(2), (2E, 4E, 8Z, 10Z)-N-isobutyl-2,4,8,10-dodecatetraenamide(3), cerotic acid(4), hyxacosyl alcohol(5).</p><p><b>CONCLUSION</b>Compounds 1,4 and 5 were obtained from the plant for the first time.</p>

Studies on water-soluble constituents of Echinacea prupurea / 药学学报

<p><b>AIM</b>To study the water-soluble constituents of Echinacea purpurea.</p><p><b>METHODS</b>The compounds were isolated by chromatography method and their structures were identified on the basis of spectral analyses.</p><p><b>RESULTS</b>Five compounds were identified as 2-(4-hydroxylphenyl)-ethyl-O-alpha-L-rhamnopy-ranoasyl-(1-->6)-beta-D- glucopyranoside, named echipuroside A 1); (6S, 9R)-6-hydroxy-3-one-alpha-inonol-9-O-beta-D-glucopyranoside 2), ampelopsisionoside 3); phenylmethyl-6-O-beta-D-xylopyranosyl(1-->6)-beta-D-glucopyranoside 4) and phyenylmethyl-beta-D-glucopyranoside 5).</p><p><b>CONCLUSION</b>Compound 1 is a new compound, the others were isolated from this plant for the first time.</p>
