Abstract

Hydrogel negatively charged (–13.5 ± 5.0 mV) calcium pectinate nano- and submicroparticles (50–150 nm) were obtained. A technique for entrapment of a plant growth regulator (trans-cinnamic acid) in the particles up to 40 wt. % has been developed. It has been established that the complete release of trans-cinnamic acid in the Murashige–Skoog medium takes 2.5 hours. The obtained particles of calcium pectinate do not affect the growth processes of cells in suspension culture and can be used as neutral carriers for growth regulators.

反式肉桂酸果胶酸钙水凝胶纳米颗粒的制备及性能研究
获得了带负电荷(- 13.5±5.0 mV)的水凝胶果酸钙纳米和亚微粒(50-150 nm)。已经开发了一种将植物生长调节剂(反式肉桂酸)包裹在高达40 wt. %的颗粒中的技术。经测定,反式肉桂酸在Murashige-Skoog培养基中完全释放需要2.5小时。所获得的果酸钙颗粒在悬浮培养中不影响细胞的生长过程,可以作为生长调节剂的中性载体。
