Webb28 apr. 2015 · Wiesner reagent (phloroglucinol in HCl) has been used as a standard stain for qualitatively assessing the presence of lignin in plant material. Phloroglucinol is a phenol derivative, which, under acidic conditions, has been shown to stain O-4-linked coniferyl and sinapyl aldehydes in lignifying cell walls (Pomar et al., 2002). WebbToluidine blue solution is used in testing for lignin, a complex organic molecule that bonds to cellulose fibres and strengthens and hardens the cell walls in plants. A positive toluidine blue test causes the solution to turn from blue to pink. A similar test can be performed with phloroglucinol - HCl solution, which turns red. bitlife unlocked pc
