Crude Extracts From Allium Cepa Skin And Sorghum Bicolor Seed Can Provide As Non-Toxic And Eco-Friendly Cytoplasmic Stains

Introduction: Staining is an important histological process; however, the use of non-toxic and environmentally friendly products is generally required. We explored the staining quality of two natural plants, Allium cepa skin and Sorghum bicolor seed extract on the cytoplasm.Materials and methods: Distilled water at 37 degrees C and 1% acid-ethanol were respectively used to extract the dyes from Allium cepa skin and Sorghum bicolor seed.Result: The application of these two dyes on rodent tissue showed an excellent cytoplasmic histomorphology.Conclusion: Allium cepa skin and Sorghum bicolor seed extracts are good cytoplasmic dyes when used as counterstain for haematoxylin.
