  1. C18-COOH Silica: Preparation, Characterisation and Its Application in Purification of Quaternary Ammonium Alkaloids from Coptis chinensis

    Qing Wang, Yao Long, Lin Yao, Mao Ye and Li Xu

    Version of Record online: 15 FEB 2017 | DOI: 10.1002/pca.2680

    The C18-COOH silica prepared by “thiol-ene” click chemistry was employed as the solid-phase extraction sorbent to purify quaternary ammonium alkaloids from Coptis chinensis. The developed method could provide a slightly higher purification efficiency (6.7%) than an alkaloid-salt precipitation protocol (5.3%) with satisfactory reproducibility.

  2. Immunoaffinity knockout of saponin glycosides from Asparagus racemosus to assess anti-lipid peroxidation

    Version of Record online: 15 FEB 2017 | DOI: 10.1002/pca.2678

    The developed immunoaffinity column coupled to monoclonal antibody recognizing shatavarin IV can isolate compounds with structures related to shatavarin IV (saponin component) from the rest (knockout component) of crude extracts of A. racemosus root. The results suggest that A. racemosus shatavarins do not inhibit carcinogenesis through preventing lipid peroxidation. The strategy described here demonstrates its utility for isolating a group of related compounds from the rest of the extract with selectivity and recovery rate.

    Prediction of Anti-Alzheimer's Activity of Flavonoids Targeting Acetylcholinesterase in silico

    Subrata Das, Monjur A. Laskar, Satyajit D. Sarker, Manabendra D. Choudhury, Prakash Roy Choudhury, Abhijit Mitra, Shajarahtunnur Jamil, Siti Mariam A. Lathiff, Siti Awanis Abdullah, Norazah Basar, Lutfun Nahar and Anupam D. Talukdar

    Version of Record online: 7 FEB 2017 | DOI: 10.1002/pca.2679

    The authors established protocols to predict the anti-Alzheimer's activity of flavonoids targeting acetylcholinesterase by the in silico approach. The key finding is that, the 5, 7 Dihydroxy-4'-methoxy-8-prenylflavanone a flavonoid could be an efficient inhibitor of AchE and thus, could be useful in the management of Alzheimer's disease.

  4. Integrated HPTLC-based Methodology for the Tracing of Bioactive Compounds in Herbal Extracts Employing Multivariate Chemometrics. A Case Study on Morus alba (pages 125–131)

    Eliza Chaita, Evagelos Gikas and Nektarios Aligiannis

    Version of Record online: 2 FEB 2017 | DOI: 10.1002/pca.2670

    Chemometric tools supported the development of a novel HPTLC-based methodology for the tracing of tyrosinase inhibitors in Morus alba extract wood. CPC fractions were assayed for tyrosinase inhibition and analyzed with HPTLC. PLS-R algorithm was performed in order to identify the compounds with the highest contribution to the biological response. Two methodologies were developed for the generation of the dataset; one based on manual peak picking and the second based on chromatogram binning.
