Objective: To determine the residues of organochlorine pesticides and heavy metals in Radix Ophiopogonis and Ophiopogon japonicus. Method: The residues of 4 isomers of benzene hexa chloride (BHC) and 4 isomers of dichloro dipheny trichloroethane (DDT) were determined by gas chromatography. The contents of Pb, Cd, Cu, Cr, Hg and As were determined by ICP. Result: The residues of organochlorine pesticides in Radix Ophiopogonis were lower than the permissible maximum limits of the Chinese national standard except hexachloride (BHC) in Radix Ophiopogonis from Cixi as well as Cu in soil of Luojiang. Conclusion: The enrichment capacity of Radix Ophiopogonis for (BHC) and Hg is higher. It is suggested that we should try to select herbs-growing soil for O. japonicus with a particular emphasis on the pesticides residues in soil. Source

Objective: To investigate the quality of Schisandra chinensis, and thus provide the useful reference data for its quality standard establishment and standardized cultivation. Method: Base on the Chinese Pharmacopoeia and literature relating to S. chinensis, the appearance, water-soluble extractive, total ash, acid-insoluble ash and volatile oil of 10 S. chinensis sampes collected from different producing sites in northease China were studied or determined, and the contents of major active lingans were measured by HPLC. Result: The content of total ash and acid-insoluble ash in S. chinensis was less than 7.0%, 1.0%, respectively. The contents of water-soluble extractive were higher than 45.0%. HPLC analyses showed that the content of schisandrol A was higher than 0.40%. All these results in accordance with the requirements of Chinese Pharmacopoeia were published in 2010. Conclusion: The differences of the appearance and the internal quality are different for the samples collected from different areas. And the establishment of a scientific and comprehensive quality standard system will be very important role in ensuring the quality of S. chinensis. Source

Objective: To compare the quality of rust rot red ginseng and injured red ginseng, and thus provide the basis for ginseng cultivation and processing. Methods: Based on Chinese Pharmacopoeia and literature related to red ginseng, ten ginsenosides, total ash, acid-insoluble ash, ether extract, carbohydrate, and total protein of red ginseng in different transplanting systems were studied or determined. Results: The contents of total ash, acid-insoluble ash, volatile ether extract, and sucrose in rust rot red ginseng are significantly higher than those in normal red ginseng. The contents of ginsenoside Rg1, Rb1, Rc, Rb2, Re, Rf, Rb3, Rd, Rg2, and Rg3 in rust rot red ginseng and injured red gingseng are significantly lower than those in normal red ginseng. Conclusion: The raw materials of rust rot red ginseng and injured red ginseng have a significant effect on the quality of the processed red ginseng. ©, 2015, Editorial Office of Chinese Traditional and.

Objective: To investigate the contents of total ginsenosides and 10 sorts of monomer ginsenosides in the roots of Panax ginseng from different habitats of northeast China and its processed products, and thus to provide the useful reference data for its quality st andard establishment and st andardized cultivation. Methods: Based on the pharmacopoeia and literatures related to the roots of P. ginseng, the contents of total ginsenosides and 10 sorts of monomer ginsenosides in the roots of P. ginseng samples collected from 10 different habitats of northeast China and its processed product samples were studied and determined, and then these various indicators were analyzed by DTOPSIS method. Results: Ginseng from Changbai, Ji'an, and Fusong reached the st andard of Chinese Pharmacopoeia 2010 and Chinese National St andards in those different measurement indicators. Comprehensive evaluation of ginseng from Changbai, Ji'an, Fusong, and Jingyu by DTOPSIS method showed better results than others. Conclusion: The qualities of ginseng from different habitats of northeast China are different. Ginseng collected from those four habitats which result better quality of ginseng than that of ginseng from other place stems from Chinese GAP ginseng planting bases, and thus reflects the importance of GAP for ginseng cultivation.

Method: Based on the Chinese Pharmacopoeia and literature relating to red ginseng, the ten ginsenosides, total ash, acid-insoluble ash, volatile oil, ether extract and total protein of red ginseng in different transplanting systems were studied or determined. Result and Conclusion: The content of total ash and acid-insoluble ash in red ginseng was less than 5.0%, 0.3%, respectively. The content of three ginsenosides (Rg1, Re, Rb1) was in accordance with the requirements of Chinese Pharmacopoeia version 2010, and the content of ten ginsenosides was significant different. Source
