Investigation of Species of Wild Chinese Medicinal Herbs for Treating Liver Diseases in Quanzhou City of Fujian Province / 中国中医药信息杂志

ObjectiveTo investigate the species of wild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province.Methods Based on the field investigation combined with literature reference, induction and analysis of the species of wild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province have been conducted.ResultsIt was found that there are 59 families, 112 genera, and 132 species of wild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province, most of which belong to angiosperm. 15 families, 21 genera, and 21 species are recorded in the Chinese Pharmacopoeia (2010 edition). Compositae has the largest number of genera and species (16 genera &19 species), followed by leguminosae (8 genera & 8 species) and labiatae (6 genera & 8 species). Chinese medicinal herbs for heat-clearing and promoting urination and leaching out damp amount to 69 and 20 species respectively. Over 88% of these wild medicinal herbs can be used to treat various liver diseases, and 46 species are used with high frequency. They are mainly taken by water decoction and oral administration.ConclusionWild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province are rich in species and resources, and are worth further development and utilization.

<p><b>OBJECTIVE</b>To study chemical constituents contained in Desmodium caudatum.</p><p><b>METHOD</b>The chemical compounds were separated by using such chromatographic methods as macroporous resin, Sephadex LH-20, ODS and normal phase silicagel column, and their structures were identified by spectroscopic data analysis.</p><p><b>RESULT</b>Fifteen compounds were separated and identified as stigmasterol (1), beta-sitosterol (2), citrusinol (3), hibiscone A (4), yukovanol (5), kenusanone I (6), neophellamuretin (7), desmodol (8), erythrotriol (9), hibiscone D (10), kaempferol (11), 8-prenylquercetin (12), leachianone G (13), 5,7,4'-trihydroxy-dihydroflavonol (14), and 4H-1-benzopyran-4-one, 2-(3,4-dihydroxyphenyl) -2, 3-dihydro-3,5,7-trihydroxy-8-( 3-methyl-2-butenyl) -, (2R-trans)-(9CI) (15).</p><p><b>CONCLUSION</b>All of the compounds were separated from D. caudatum for the first time except compound 8.</p>

Determination of protopine in Corydalis racemose by HPLC / 中国中药杂志

<p><b>OBJECTIVE</b>To develop a HPLC method for determining the content of protopine in Corydalis racemose.</p><p><b>METHOD</b>Analysis was performed on a Gemini C18 column (4.6 mm x 250 mm, 5 microm) eluted with acetonitrile-water containing 0.8% triethylamine and 3% acetic acid acetum (20:80) as the mobile phase. The flow rate was 1.0 mL x min(-1). The detection wavelength was 289 nm.</p><p><b>RESULT</b>The average content of protopine in Herb of Racemose Corydalis was 0.905%. The calibration curve of protopine was linear between 0.124-1.36 microg (r = 0.9999). The average recovery was 98.49% with RSD 1.9%.</p><p><b>CONCLUSION</b>This method is simple, reproducible and can be used to determine the content of protopine in C. racemose.</p>

Flavonoid constituents from herbs of Sarcopyramis bodinieri var. delicata / 中国中药杂志

Phytochemical studies of the the herb Sarcopyramis bodinieri var. delicate (Melastomataceae) have been carried out. The compounds were separated by repeated D101 macroporous adsorption resin column combined with Sephadex LH-20, ODS, and silica gel chromatgrophy. The structures were identified on the basis of extensive spectroscopic data analysis, and by comparison of their spectral data with those reported. Eight flavonoid compounds isolated from the ethyl acetate extract was identified as isorhamnetin (1), quercetin (2), isorhamnetin-3-O-beta-D-glucopyranoside (3), quercetin-3-O-beta-D-glucopyranoside (4), isorhamnetin-3-O-(6"-acetyl)-beta-D-glucopyranoside (5), isorhamnetin-3-O-(2"-acetyl)-beta-D-glucopyranoside (6), quercetin-3-O-(6"-acetyl)-beta-D-glucopyranoside (7), and quercetin- 3-O-(6"-O-E-p-coumaroyl)-beta-D-glucopyranoside (8). All of the compounds were separated from the genus of Sarcopyramis for the first time.
