The analytical and toxicological profiles of the red dye from the heart wood of Caesalpinia sappan

Authors and affiliation (s):


Three phenolic red pigments were observed in combination from the heart wood of Caesalpinia sappan (F: Caesalpiniaceae). Preliminary cytotoxic and acute toxicity studies indicated that these natural colour pigments were safe compared to the FDC grade coal tar dyes. The isolated colour extract (CSWC) was highly soluble in water and analysed by spectrophotometric and HPTLC methods.
