火炭母的显微和光谱鉴别

Macroscopic and UV-Vis Spectrum Identification Research on Polygonum chinense L.

[目的]研究火炭母的生药学特征。[方法]分别对火炭母药材进行性状鉴别和显微鉴别,然后采用紫外-可见分光光度法对火炭母进行生药鉴别研究。[结果]火炭母根横切面皮层狭窄,韧皮部成环;茎中柱鞘纤维波浪状排列成带状;叶主脉维管束2～6个排列成环,2侧均有木化纤维束;叶上表皮具类圆形分泌细胞与多细胞腺毛;下表皮具多细胞腺毛,不等式或不定式气孔多见;粉末中腺毛、分泌细胞、花粉粒、晶鞘纤维、棕色条块和淀粉粒各异;紫外-可见光谱在200～800 nm扫描,发现5种不同的提取液都有吸收峰。[结论]试验研究了火炭母生药学特征,为鉴定、开发利用和制定其质量标准提供参考依据。

[Objective] The aim was to study the pharmacognosy of Polygonum chinense L.[Method] Through microscopic identification and UV-Vis Spectrum,the pharmacognosy of Polygonum chinense L.was studied.[Result] Cortex of Polygonum chinense L.was narrow and phloem into ring in the root;The pericycle fibers were arranged in strips in stem.The 2-6 main vein vascular bundled,which both sides of fiber bundle were arranged in a ring,The round secretory cells and multicellular glandular hairs on the Leaf epidermis,the multicellular glandular hairs,and unequal or infinitive hole saw under the skin;palisade tissue of leaf through primary vein.There were many glandular,secreting cell,pollen grains,crystal fiber sheaths,brown compartmentalization,starch grains in the powder.Five kinds of solvent of crude drug had absorption peaks in 200-800 nm,respectively.[Conclusion] The test studied the characteristics of Polygonum chinense L.and it provided reference for the identification,application and formulation of its quality standard.
