目的对怀地黄脱毒后品质进行评价。方法以怀地黄“85-5”脱毒试管苗和未脱毒试管苗的块茎为材料,对其梓醇及营养成分的量进行分析。结果脱毒试管苗块茎的梓醇量高于未脱毒试管苗块茎,但不同的脱毒株系间梓醇量存在较大差异,其中梓醇量最高的株系可达6.43%,较对照增加33.13%;脱毒试管苗块茎中,粗脂肪、粗蛋白质的量均得到提高。结论怀地黄脱毒后品质得到显著改善。 Objective To evaluate the quality of detoxification of Rehmannia glutinosa. Methods The contents of sterols and nutrients were analyzed with tubers of virus-free and tuber-free seedlings of Huai Di Huang “85-5”. Results The amount of sterols in tubers of virus-free test tubes was higher than that of non-detoxified tubers, but there was a great difference in the amount of sterols among the different detoxified strains. Among them, the highest amount of sterols was 6.43%. An increase of 33.13%; the amount of crude fat and crude protein in tubers of virus-free test tubes was improved. Conclusion The quality of detoxified Huai Di Huang was significantly improved.
