作者前曾由中药木通中提出一种酸性含氮化合物,经元素分析及分子量测定结果,暂定其分子式为 C_(12)H_(11)NO_+,熔点281—282°。其化学及物理性质与作者前研究国产木防已甲素,熔点280—281°,C_(32)H_(24)N_2O_(12(13))(或 C_(16)H_(12)NO_(6(7))),及土青木香丙素,熔点278—280°,C_(33)H_(23)NO_(14),有些相似。当时因原植物不明,所得金黄色棒状结晶,暂名木通甲素。前精制甲素时仅用甲醇及丙酮交互重结晶,未用硷、酸及二甲基甲酰胺处理,含不纯物,所以有更正及补充必要,并进行铿定之。
The author had previously proposed an acidic nitrogen-containing compound from the traditional Chinese medicine Mutong. The molecular formula was tentatively determined by elemental analysis and molecular weight determination as C_(12)H_(11)NO_+, melting point 281–282°. Its chemical and physical properties were compared with those of the authors before the study of domestic wood defense A, the melting point of 280-281°, C 32 H 24 N 2 O 12(13) (or C 16 H 12 NO 6 ) (7))), and AQM, melting point 278-280°, C_(33)H_(23)NO_(14), somewhat similar. At that time, because of the original plant is unknown, the gold rod-shaped crystals obtained, temporary name Mutong A. When pre-purified A is only recrystallized with methanol and acetone, it is not treated with hydrazine, acid and dimethylformamide, and contains impurities, so it is necessary to make corrections and supplements.
