Abstract: In order to investigate the effect of physical and chemical factors on anthocyanin stability in Hyacinthus, the petals of hyacinthus ‘Woodstock' was used to study the effects of temperature, light, pH and metal ions on the changing patterns of the color of anthocyanin extraction and spectral characteristics by experiments in vitro. The results showed that the anthocyanidin from hyacinthus petals was not tolerant to high temperature and strong light, and pH exerted remarkable effects on anthocyanins since there was a bathochromic shift of the maximwm absorption warelengte as the increase of pH value. Fe3+, Fe2+, Al3+ and Cu2+ changed the color of anthocyanins, but the influence of Mg2+ was not significant. High concentration of Ca2+ and Zn2+ produced the hyperchromicity effect, while Pb2+ created white precipitation in anthocyanin solution. High concentration of Fe2+ and Pb2+ caused the maximum wavelength blue shift, yet the other metal ions showed bathochromic shift effect with the increase concentration to various degrees. These results could provide some scientific basis to explore the mechanism of flower color formation in hyacinthus, identifying the structure of the hyacinthus anthocyanin and further utilizing the hyacinthus pigment.
