Medium- and light-induced formation of serpentine and anthocyanins in cell suspension cultures of Catharanthus roseus

摘要: Abstract By irradiation with fluorescent light, medium-induced cell cultures of Catharanthus roseus accumulated anthocyanins and the indole alkaloid serpentine. The formation both compounds was inhibited by phosphate nitrogen-containing mineral salts stimulated high sucrose concentrations. accumulation serpentine preceded an increase subsequent decrease its biogenetic precursor ajmalicine, which predominant in dark. High concentrations or were observed only a small proportion all cells present culture. aglycones identified as petunidin, malvidin hirsutidin.
