摘要
[目的]比较研究宁夏人工种植黄芩与野生黄芩的性状特征、显微特征及主要黄酮类化学成分含量的特性。[方法]从形态学角度观察药材的形状、大小、颜色、质地、断面特征、气味等来比较人工种植黄芩药材与野生黄芩的性状特征的异同;从细胞学角度观察人工种植黄芩的组织构造、细胞特征、细胞后含物等显微特征来比较人工种植黄芩药材与野生黄芩之间的差异;用RP-HPLC法对人工种植黄芩和野生黄芩中黄芩苷含量进行检测。[结果]宁夏种植黄芩的性状、显微特征与野生黄芩有细微的变化,但基本符合《中国药典》2010版的描述;3个不同栽培基地的栽培品中黄芩苷含量分别为16.90%、15.26%和15.47%,均高于野生黄芩中黄芩苷的含量(9.84%),均大于《中国药典》2010版中要求的9.0%的最低限度。[结论]宁夏六盘山人工种植黄芩的质量符合《中国药典》2010年版的规定,可以大力推广规范化种植和实现产业化发展,为缓解黄芩市场需求作出贡献。
[Objective] The aim was to study on the pharmacognostic characteristics,microscopic characteristics,and the main content of flavonoids in cultivated and wild SCUTELLARIAE RADIX in Ningixia,China.[Method] From the aspect of morphology,the shape,size,color,texture,cross-section characteristics,odor of herbs were compared,so as to find out the differences in pharmacognostic characteristics between cultivated and wild SCUTELLARIAE RADIX.Besides,from the cytological point of view,the histological structure,cell characteristics,cell ergastic substance and other microscopic characteristics of cultivated SCUTELLARIAE RADIX were studied and compared with the wild SCUTELLARIAE RADIX.RP-HPLC method was used to detect the baicalin contents in cultivated and wild SCUTELLARIAE RADIX.[Result] The properties and microscopic characteristics of cultivated SCUTELLARIAE RADIX in Ningxia,China had slight differences with those of wild SCUTELLARIAE RADIX,but basically accorded with the description in 2010 Chinese Pharmacopoeia.Baicalin contents in cultivated SCUTELLARIAE RADIX in 3 different cultivation bases were 16.90%,15.26%,and 15.47%,which were all higher than the content of wild SCUTELLARIAE RADIX（9.84%） and exceeded the lowest limit in 2010 Chinese Pharmacopoeia（9.0%）.[Conclusion] The cultivated SCUTELLARIAE RADIX in Liupan Mountain of Ningxia met the quality requirements in 2010 Chinese Pharmacopoeia.Therefore,the normalized cultivation could be widely popularized,in order to realize the industrialized development and to relief the market demand for baicalin.
