Three new alkaloids were isolated from the root-wood of Brucea mollis var. tonkinensis collected in China. Their structures were determined to be 11-O-beta-D-glucopyranosyl-(1-->6)-beta- D-glucopyranosylcanthin-6-one, 5-O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosylcanthin-6-o ne and 11-hydroxycanthin-6-one-N-oxide, by chemical and spectral methods. In addition, two known alkaloids, canthin-6-one and canthin-6-one-N-oxide, were isolated.
从采自中国的东京鸦胆子软叶变种的根木中分离出三种新生物碱。通过化学和光谱方法确定它们的结构分别为11 - O - β - D - 吡喃葡萄糖基 - (1→6) - β - D - 吡喃葡萄糖基铁屎米 - 6 - 酮、5 - O - β - D - 吡喃葡萄糖基 - (1→6) - β - D - 吡喃葡萄糖基铁屎米 - 6 - 酮和11 - 羟基铁屎米 - 6 - 酮 - N - 氧化物。此外，还分离出两种已知生物碱，铁屎米 - 6 - 酮和铁屎米 - 6 - 酮 - N - 氧化物。
