摘 要 ：通过以不同用量（种子干重的2%，4%，6%和8%）的黄芪种衣剂包衣种子为处理组，以ND牌种衣剂（种子干重的8%）包衣和空白种子为双对照组，比较研究在不同种子处理条件下，膜荚黄芪植物中黄芪甲苷含量、总黄酮含量及农药残留量发生变化情况。研究结果表明，黄芪种衣剂包衣处理后，明显增加了黄芪中有效成分黄芪甲苷、总黄酮的含量，且包衣所产生的农药残留可随植物生长完全降解掉，研究结果表明黄芪种衣剂的使用可以提高中药材黄芪的品质。

Abstract:The quality of astragalus membranaceus was studied with the treatment of Astragalus membranaceus seed coating by different concentrations (2%, 4%, 6% and 8% of seed dry weight), ND general seed coating (8% of seed dry weight) and seed uncoated. The contents changes of astragaloside Ⅳ, total flavonoids and pesticide reside were analyzed.The results indicated that treated by astragalus membranaceus seed coating. It could both improve the main active component-astragaloside Ⅳ and total flavonoids in radix astragali, and the pesticide residue of seed coating could be fully degradationed with the grow of plants. Proved that seed coating can improve quality of A. membranceus(Fisch) Bge.
