    • Disclosed are methods for obtaining a natural product preparation with reduced glucosinolate contamination from a plant of Brassicaceae. The methods can include cultivating a plant callus from a plant capable of producing a desired natural product, selecting a callus with reduced glucosinolate production, and cultivating the selected callus in a liquid medium. The method can also include recovering the natural product from the culture. Also disclosed are methods for obtaining cabbage anthocyanin with reduced glucosinolate contamination. The methods can include cultivating a red cabbage plant callus with reduced glucosinolate production in a liquid medium to obtain a suspension culture and cultivating the suspension culture in a medium lacking a nitrogen source. The method can also include recovering the anthocyanin with reduced glucosinolate contamination from the culture. Finally, several specific low-glucosinolate cell lines are described.
    • 公开了用于从十字花科植物获得具有降低的硫代葡萄糖苷酸污染的天然产物制剂的方法。 所述方法可以包括从能够生产期望的天然产物的植物中培养植物愈伤组织,选择具有降低的硫代葡萄糖苷产生的愈伤组织并且在液体培养基中培养所选择的愈伤组织。 该方法还可以包括从培养物中回收天然产物。 还公开了获得具有降低的硫代葡萄糖苷酸污染的卷心菜花青素的方法。 所述方法可包括在液体培养基中培养具有减少的硫代葡萄糖苷产生的红球甘蓝植物愈伤组织以获得悬浮培养物,并在不含氮源的培养基中培养悬浮培养物。 该方法还可以包括从培养物中回收具有减少的硫代葡萄糖苷酸污染的花青素。 最后,描述了几种特定的低芥子油苷细胞系。
