Determination of β-carotene in jute leaves by spectrophotometry and thin layer chromatography

β-carotene is a carotenoid pigment that converts to vitamin A in human body and plays crucial role visual functions, reproductive performance immune system. Jute leaves contain but amounts different varieties of jute are not known. The study was undertaken estimate the content fresh cultivated species Corchorus olitorius L. capsularis by spectrophotometry thin layer chromatography. varies two species. Leaves some C. variety showed higher amount than variety. Some similarity with capsularis. Variety Robi-1 C .olitorius highest 39.93mg/100g.
