Abstract:
To establish the suspension culture system of Silybum marianum cell and study the effects of different factors on silybin content. Orthogonal test was adopted to determine S. marianum cell suspension culture system and HPLC to silybin content.. The best growth cycle of cell suspension culture was defined when cultured in liquid MS medium with 6-BA 1.5 mg/L + NAA 1.0 mg/L + ZT 1.5 mg/L, light 12 h/d, pH value = 7, revolution = 110 r/min. The effects of salicylic acid, chitosan, and sodium nitroprusside on cell suspension culture were investigated. When the concentration of three impact factors were 0.05, 3, and 1 μ g/L, respectively, the growth amount of S. marianum cell reached the maximum, i. e. At the same time, the silybin content also reached the maximum. The established cell suspension culture system is suitable to use for the rapid propagation of S. marianum. Chitosan and sodium nitroprusside at proper concentration are benifit to the growth of suspensious cells and accumulation of silybin.
