Various cell wall polysaccharides such as ionically associated pectin (IAP), covalently bounded pectin (CBP), 4N potassium hydroxide soluble hemicellilosic fraction (HF1) and 0-3N soluble hemicellulosic fraction (HF2) were fractionated from crude cell wall of the fresh and soft persimmon by chemical method. The changes in cell wall polysaccharides were studied by gel filtration chromatography. The content of crude cell wall remarkably decreased in the soft persimmon. The decreasing rates of IAP, CBP and HF2 were 59, 60 and 74% respectively, while HF1, and cellulose changed only a little during softening
