报道从贝母属植物中分离出的65个生物碱的13CNMR化学位移数据，并将其进行分类、归纳。指出文献中生物碱的13CNMR化学位移归属存在的错误，阐述生物碱结构不断被修正的必然性，以及用13CNMR谱确定生物碱的结构。
The 13C NMR chemical shift data of 65 alkaloids isolated from Fritillaria are reported and classified and summarized. It points out the errors in the 13C NMR chemical shift attribution of alkaloids in the literature, explains the inevitability of alkaloid structure being constantly corrected, and uses 13C NMR spectroscopy to determine the structure of alkaloids.
