Pachysandra型生物碱^（13）CNMR谱的研究

STUDY ON ^(13)C NMR SPECTROSCOPY OF PACHYSANDRA ALKALOIDS

文献中未报道过Ｐａｃｈｙｓａｎｄｒａ型生物碱的￣（１３）ＣＮＭＲ数据，在研究这类化合物的化学结构的基础上，本文系统地研究了Ｐａｃｈｙｓａｎｄｒａ型生物碱的￣（１３）ＣＮＭＫ谱，完整归属了化学位移数据，探讨了￣（１３）ＣＮＭＲ规律和特征。

Natural abundance^(13)C NMR spectra of more than thirty natural Pachysandraalkaloids and their derivatives were recorded． The assignments were made with the helpof DEPT technique， based on chemical shifts arguments and comparison with values re-ported for other related steroidal alkaloids．The application of^(13)C NMR spectral ana-lysis for the structure elucidation of Pachysandra alkaloids is discussed.
