目的采用红外指纹图谱方法,对目前医药市场上中药材柴胡的真伪进行鉴别.方法应用红外标准图谱的方法,将我们测得的红外标准图谱与全国10个城市购买的柴胡样品以及柴胡伪品的红外图谱进行相似度对比.结果柴胡红外标准图谱与样品图谱相似度极高,与伪品相似度较低.结论采用红外图谱的方法对柴胡进行质量控制是可行的. 相似文献

The protoplasts of Red Thorowax ( Bupleurum scorzonerifolium) irradiated by ultraviolet light (UV) at an intensity of 260μW/cm2 for 0, 1,2 and 3 min respectively were fused with that of grapevine ( Vitia vinifera). The regenerated 19 clones, every one derived from a single fused cell, were identified as hybrids by phenotype, isozyme, chromosome and 5S rDNA spacer region analysis. The results reveal that all of them are somatic hybrids. 11 hybrid calli including asymmetric and symmetric products regenerated somatic embryos and young leaves after 5 months of culture, of which 4 hybrid cell lines derived from asymmetric fusion regenerated plants with roots after 8-10 months of culture. Inspection of chromosome showed that regeneration of whole plant was related to the decrease of chromosome number. Identification of 5S rDNA spacer region of the plants confirmed that they were interfamilial hybrid plants. 相似文献

内蒙古柴胡属植物花粉形态及其分类 总被引:1,自引:0,他引:1
本文首次用扫描电镜观察了内蒙古柴胡属7种11株植物的花粉形态。该属植物花粉形态相对一致,但在花粉粒形状、纹饰细微结构和孔膜等方面有差异。根据形状和孔膜特点本属花粉可分为近菱形,卵形和近长方形等三类;以外壁纹饰特征又可分为皱波状纹饰较明显和不明显两类,后两类与以小总苞片特征所得的类群基本吻合。柴胡属某些种花粉形态在种内有变异现象。 相似文献
