  • Identification and S-metolachlor-safening Effects of Compounds Extracted from Ligusticum Chuanxiong on Rice
    International Journal of Agriculture and Biology, 2016
    Co-Authors: Wei Zheng, Yan-hui Wang, Cai Hailin, Chenzhong Jin, Xiu Liu, Lian-yang Bai
    Abstract:

    In this study, the effects of Ligusticum Chuanxiong Extract as herbicide safeners were determined on glutathione-S-transferase (GST) activity of rice crop. Two main Extract compounds, Z-ligustilide and senkyunolide A, were identified by high performance liquid chromatography and liquid chromatography-mass spectrometry. In both bioassays conducted in agar and soil, the whole L. Chuanxiong Extract, as well as two active components individually were effective in safening the growth of rice seedlings against S-metolachlor toxicity. Z-Ligustilide was a better safener than senkyunolide A, and both compounds were more protective of shoots than roots. After herbicide-inhibited rice seedlings were treated with Z-ligustilide, GST activity significantly increased, suggesting the safening effect of this L. Chuanxiong Extract component involves GST. © 2016 Friends Science Publishers

  • Profiling of Permeable Compounds in Ligusticum Chuanxiong by Biopartitioning Micellar Chromatography
    Chromatographia, 2009
    Co-Authors: Wei-nong Zhang, Yu-qi Feng
    Abstract:

    The potential of biopartitioning micellar chromatography (BMC) for screening and analysis of traditional Chinese medicines (TCM) for permeable compounds has been investigated by chromatography of methanolic Extracts of Ligusticum Chuanxiong, as example. Six other ordinary TCM were also studied. Results showed that more than ten components of Ligusticum Chuanxiong Extract are significantly retained in BMC. According to relationships between retention in BMC and oral drug absorption, cell-membrane permeability, and blood–brain barrier permeability, the cell-membrane permeability and absorption properties of the permeable components of Ligusticum Chuanxiong Extract could be predicted from their retention in BMC. Effects on the chromatography of components of Ligusticum Chuanxiong methanolic Extracts of column temperature, mobile phase pH, and concentration of Brij 35 in the mobile phase are also discussed.
