板蓝根和南板蓝根的显微结构比较(英文)

A Comparative Study on Microstructure between Isatis indigotica Fort.and Baphicacanthus cusia(Nees) Bremek.

[目的]对板蓝根和南板蓝根进行显微结构的研究。[方法]应用数码显微技术对市售不同来源的板蓝根和南板蓝根进行了显微结构的比较与分析。[结果]在两者的显微结构上,板蓝根中多见网纹导管、单粒淀粉、复粒淀粉、石细胞;南板蓝根中多见孔纹导管、具细小纹孔的薄壁细胞、单粒淀粉、钟乳体,这表明板蓝根和南板蓝根的显微结构差异显著。[结论]该研究所建立的板蓝根和南板蓝根显微结构特征可用于2种中药材的质量评价,同时也为全面研究板蓝根和南板蓝根的质量标准提供了科学依据及方法学的保障。

[Objective] This study aimed to compare the microstructure between I. in- digotica Fort. and B. cusia （Nees） Bremek. [Method] Microstructure of I. indigotica Fort. and B. cusia （Nees） Bremek. with different sources were compared and analyzed by using digital microscopy. [Result] Comparison result of the microstructure shows that reticulate vessels, single starch granules, multiple starch granules and stone cells are mostly observed in I. indigotica Fort.; pitted vessels, parenchyma cells with small pits, single starch granules and cystolith are mostly observed in B. cusia （Nees） Bremek., which indicated that microstructure of L indigotica Fort. and B. cusia （Nees） Bremek. are significantly different. [Conclusion] Microstructure char- acteristics of I. indigotica Fort. and B. cusia （Nees） Bremek. established in this study can be used to evaluate the quality of these two kinds of Chinese herbal medicines, which also provide scientific basis and methods for comprehensively studying the quality standard of /. indigotica Fort. and B. cusia （Nees） Bremek. Key words Isatis indigotica Fort.; Baphicacanthus cusia （Nees） Bremek.; Microstruc- ture; Quality
