    • Microwave-assisted extraction and identification of polysaccharide from Lycoris aurea 

      Ru, Q. M.; Zhang, L. R; 张连茹; Chen, J. D.; Pei, Z. M.; Zheng, H. L.; 郑海雷 (SPRINGER, 2009)
      Three polysaccharide fractions (LAP-1, LAP-2, and LAP-3) were separated from the extract of Lycoris aurea using DEAE-52 and Sephadex G-150 column chromatography. FT-IR spectroscopy revealed the typical characteristics of ...
    • Physiological and comparative proteomic analyses in response to nitrogen application in an Amaryllidaceae plant, Lycoris aurea 

      Ru, Q. M.; Wang, X.; Liu, T. W.; Zheng, H. L.; 郑海雷 (2013-01)
      Galanthamine is used as a strong reversible inhibitor of cholinesterase to increase acetylcholine sensitivity. Here, we sought to determine the effect of nitrogen (N) application on physiological and proteomic properties ...
    • 忽地笑愈伤组织培养条件对加兰他敏合成的影响 

      茹巧美; 裴真明; 郑海雷 (2010)
      研究了忽地笑次生代谢产物加兰他敏的合成以及各种理化因子对加兰他敏合成的影响。结果表明,蔗糖是忽地笑愈伤组织培养的最佳碳源,而且在90 g/l浓度培养下加兰他敏含量最高,达到0.068%;附加500 Mg/l苯丙氨酸前体物也可提高加兰他敏产量。酪氨酸和水杨酸不利于加兰他敏的积累。此外,2,4-d和浓度高于0.5 Mg/l的nAA、IbA抑制加兰他敏的合成,但高浓度的6-bA却对加兰他敏的合成起促进作用。
