苋色藜细胞培养产生的天然红色素性质及其稳定性

从苋色藜 (ChenopodiumAmaranticolor)的愈伤组织中提取天然红色素 .此色素对热较敏感 ,对紫外线不敏感 ,在 pH 5～ 1 0稳定 ,Fe3 、Cu2 和氧化剂对其有破坏作用 ,Fe2 、Al3 和还原剂有一定的保护作用 .比较MS和B5 培养基 ,前者对苋色藜愈伤组织产色素有利 .

The Natural Red Pigment Produced by Plant Cells

The natural red pigment was extracted from callus of Chenopodium amaranticolor. The effects of physical and chemical factors (such as light, temperature, pH, metal ions, oxidants and reductants) on the stability of the pigment were discussed.The action of mediums (MS and B 5) on the yield of the pigment was compared. The pigment has the maximum absorbing wavelength at 540 nm. Some chemicals, such as Fe 2 , Al 3 , showed protective action at the pigment.And the medium MS adapted to the cells to produce the pigment.
