Abstract:
Taking Dendrobium candidum as material,wet u1trafine grinding technology was used to extract Dendrobium candidum polysaccharide.The effect of gap of mill teeth,ratio of solid to liquid,extraction temperature and extraction time on yield of polysaccharide were studied by single factor test, and orthogonal test was used to optimum extraction conditions.The results showed that optimum conditions were gap of mill teeth 30 μm,ratio of solid to liquid 1∶14 g/mL,extraction temperature 70℃ and extraction time 31 min.The yield of Dendrobium candidum polysaccharide was 16.48%.Wet u1trafine grinding extraction was a suitable method for extraction of Dendrobium candidum  polysaccharide.
