银柴胡与党参为常见中药材,它们的栽培品外形酷似,易混淆。最近在南宁市发现将家种银柴胡掺杂在家种党参中的情况。关于家种党参、家种银柴胡的性状、显微鉴别及泡沫试验的方法已有报道。为此,笔者对两者进行了一阶导数光谱法鉴别。 1 实验材料及仪器 家种党参为桔梗科植物党参Codonopsis pilosula(Franch.)Nannf.的干燥根,A、B、C分别产于甘肃、湖北、山东。家种银柴胡为
Silver Bupleurum and Codonopsis pilosula are common Chinese herbal medicines. Their cultivars are very similar in shape and confusing. Recently in Nanning City, it was discovered that the native species of silver and Bupleurum was doped in Dendrobium species. The traits, microscopic identification, and foam test methods of the species of Codonopsis pilosula and home-grown Silver Bupleurum have been reported. To this end, the author conducted a first-order derivative spectroscopy to identify the two. 1 Experimental materials and instruments The species of Codonopsis pilosula is the dried root of Codonopsis pilosula (Franch.) Nannf., which is produced in Gansu, Hubei and Shandong provinces. Homegrown Silver Bupleurum
