摘要 目的:探讨维药芜菁子性状、显微和化学成分的特征,为制定其质量标准提供依据。方法:对不同产地10批药材,采用显微照相技术观察显微特征,根据《中国药典》标准方法检测水分、灰分、杂质、酸不溶物、浸出物含量,利用气相色谱-质谱联用分析油脂的化学组成。结果:可以作为显微鉴定的特征有子叶、栅状细胞、非腺毛和内胚乳,粉末特征有栅状细胞、子叶细胞和非腺毛;提出了药材水分不得多于6%、杂质不得多于4.5%、总灰分不得多于6%、酸不溶性灰分不得多于0.7%、水溶性浸出物不得少于11%的参考范围;油脂成分主要含芥酸、油酸、γ-谷甾醇。结论:实验方法准确可靠,以上检测指标和参数可以作为制定芜菁子质量标准的依据。 Objective : To explore the physical and behavioral, microscopic and chemical characteristic traits of Brassica rapa, and supply scientific bases for establishing its quality control standard. Method: Microscopic identification method was adopted to observe the microscopic characters of ten batches crude drugs, the contents of water, impurity, total ash, insoluble acid ash and extrac- tives were detected based on Chinese Pharmacopoeia (2010) , and the oil constituents were analyzed by gas chromatography-mass spectrometry (GC-MS). Result: The microscopic traits were cotyledon, palisade cells, non-glandular hairs and inner endosperm, while the palisade cells, cotyledon cells and non-glandular hairs existed in its powders. The results confirmed the contents of water, impurity, total ash and insoluble acid ash should be fewer than 6% , 4. 5%, 6% ,0. 7% , while the content of extractives should exceed 11%. The main oil compounds in it were erucic acid, oleic acid and T-sitosterol through the GC-MS analysis. Conclusion: The experimental methods were accurate and reliable, and the indexes and parameters may be thought as the quality standards for B. rapa.
