- 中文摘要:
The absorption maxima of the fluorescence spectra of the berberine series alkaloids are broadly distributed between 360 and 560 mμ.
The fluorescence spectra of most substances of this series are very monotonous one having a single peak, the spectra of tetrahydro-coptisine and tetrahydroepiberberine are quite exceptional and consist of two wavy bands.
The introduction of the auxochrome group into the molecule of “proto” compounds causes the decreasing of the fluorescence intensity and this effect is strongest in case of transition from protoberberine to berberine.
That, tetrahydropalmatine does not show the distinct fluorescence spectrum band is the only incomprehensible fact. - 英文摘要: --
