十年来吲哚生物碱的成就构成了生物碱化学中最为特出的一部分,这些成就的取得,一方面由于生物碱本身独特的生理作用和复杂的结构,因而具有广泛的医疗价值,并引起天然有机工作者的浓厚兴趣;另一方面客观上又因分离提纯技术的进步,紫外、红外吸收光谱、核磁共振、X射线分析、质谱、旋光色散、气体层析等物理方法的广泛应用,反应机理和立体化学理论的发展,为吲哚生物碱的研究提供了技术基础.按专业参考书的记载,吲哚生物碱结构的解决,1955年约为50种,1960年达200种,至1963年6月已超过300种.这些生物碱中约3/4具有色胺-预苯酸甲醛(tryptamine prephanic formaldehyde)基本
The achievement of alkaloids in the past decade has constituted the most outstanding part of alkaloid chemistry. The achievement of these achievements is due to the unique physiological effects and complex structures of alkaloids, which have extensive medical value and cause natural The organic interest of organic workers; objectively, due to advances in separation and purification technology, UV, infrared absorption spectroscopy, nuclear magnetic resonance, X-ray analysis, mass spectrometry, optical dispersion, gas chromatography and other physical methods are widely used, and the reaction mechanism The development of stereochemistry theory provides the technical basis for the study of indole alkaloids. According to the records of professional reference books, the resolution of indole alkaloid structure was about 50 species in 1955 and 200 species in 1960 to 1963. Over 300 species in June. About 3/4 of these alkaloids have tryptamine prephanic formaldehyde
