During callus culture, the content of Berberine that is main component of the alkaloids in intact plant was lower than that in intact plant ( except for stationary phase), whereas jatrorrhizine that was negligible quantity in intact plant to be main alkaloid in cultural cell. 在培养细胞中是主要的生物碱,而原植物中为主要成分的小檗碱,在培养细胞中的含量(除静止期外)低于原植物。
The product contains more than 93% TiO_2, keeps the original grain size and has a negligible quantity of fines. 产品含TiO293%以上,保持原矿粒度,没有细粉。
But compared to the theoretical value of the added mass gained by the theory of potential flow, the increment is a negligible quantity. 但是这个增量与附加质量势流解的理论值相比很小,可以忽略不计。
