抄録
Two new steroidal alkaloids, paxillarines A (1) and B (2), were isolated from Pachysandra axillaris. Their structures were determined by means of spectrometric methods as 3α-N-methylbenzoylamino-4β-acetoxy-16β-hydroxy-20α-dimethylamino-5α-pregnane and 3α-N-methylbenzoylamino-4β-acetoxy-12β-hydroxy-20α-dimethyl-amino-5α-pregnane, respectively. Some of the expected characteristic 1H-NMR signals were not observed due to hindered rotation when the spectra were measured on a 400 MHz spectrometer, although all of the signals appeared clearly on a 90 MHz machine. The conformation of the ring A moiety of these alkaloids is discussed.
