Antitumor Effects of Microencapsulated Extract on Breast Carcinoma and Human Cervical Cancer Cells In Vitro.

Flavonoid-containing extract has been studied in relation to breast carcinoma and human cervical cancer cells in encapsulated and native form. Encapsulation was realized in polymer shells, which were formed by the layer-by-layer method using sequential adsorption of poly(allylamine hydrochloride) and poly(sodium 4-styrenesulfonate) on the destructible cores. The extract was prepared by the author's method and characterized using high performance liquid chromatography.
