A new phenolic amide glycoside from Cimicifuga dahurica / 药学学报

A new phenolic amide glycoside, cimicifugamide A (1) along with four known compounds, trans-feruloyl tyramine 4-O-beta-D-glucopyranoside (2), (+)-isolariciresinol 3-O-beta-D-glucopyranoside (3), cimidahurine (4), and 24-epi-7, 8-didehydrocimigenol-3-O-beta-D-xylopyranoside (5) were isolated from the rhizomes of Cimicifuga dahurica. Compound 3 was identified as a lignan and has been obtained from Cimicifuga genus for the first time. The structure of compound 1 was elucidated by IR, UV, HR-MS and NMR spectroscopic methods.

HPLC determination of four active components in dengzhanxixin injection / 中国中药杂志

<p><b>OBJECTIVE</b>To establish a method for determination of chlorogenic acid, caffeic acid, caffeoylquinic acid and ScuteIlarin in Dengzhan Xixin injection.</p><p><b>METHOD</b>The HPLC method was carried out on Agilent Zorbax SB-C18 column (150 mm x 4. 6 mm, 5 pim) evaluated with acetonitrile-0.1% formic acid as mobile phase, gradient elution; the flow rate was 1.0 mL x min(-1); the temperatue of column was at 35 degrees C; the detection wavelength was at 335 nm for UV detection.</p><p><b>RESULT</b>The calibration curves were linear in the range of 0.025 to 0.800 microg (r = 0.9990) for chlorogenic acid, 0.027 to 0.850 microg (r = 0.9999) for caffeic acid, 0.062 to 1.978 microg (r = 0.9997) for caffeoylquinic acid and 0.118 to 3.770 microg (r = 0.9999) for scutellarin,respectilely. The average recoveries were 97.19% with RSD 1.16%; 100.45% with RSD 1.16%; 97.32% with RSD 1.43% and 103.81% with RSD 0.70%, respectively.</p><p><b>CONCLUSION</b>The assay demonstrated that the method was simple, it had adequate accuracy and selectivity to quantify the four active components in Dengzhan Xixin injection.</p>

Determination of danshensu in rat serum after oral administer compound Salvia recipe / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the absorption of the water soluble components of Salvia miltiorrhiza and establish methods to determine Danshensu in rat serum after ig compound Salvia recipe.</p><p><b>METHOD</b>Used liquid-liquid extraction to deal with the serum, then determined the sample by high-performance liquid chromatography. The conditions for HPLC were as the following: the mobile phase, CH3OH-CH3CN-0.5% CH3COOH (2.5:3.5:94) with a flow rate of 1.0 mL.min-1; detection wavelength, 281 nm; internal standard, 4-hydroxy-benzoic acid.</p><p><b>RESULT</b>Danshensu and an unknown compound whose reserved time was little shorter than protocatechuic aldehyde were found in the rat serum after ig compound Salvia recipe, while protocatechuic aldehyde weren't found in the serum.</p><p><b>CONCLUSION</b>Danshensu can be absorbed into blood after ig compound Salvia recipe.</p>
