The advantages of new method - extraction of natural alkaloids with diluent gas

摘要

Alkaloids are the natural compounds which mostly contain basic nitrogen atoms. They are characterized by multilateral pharmacological activity, broad spectrum of therapeutic action and hypo toxicity. Receipt of herbal alkaloids is difficult technological process connected with heavy financial expenses. Together with it, there are used organic solvents polluting environment and finished product. The purpose of our research was to develop of alternative and safe technologies of herbal alkaloids receipt. Extraction of alkaloids from medicinal herbal raw material was realized by two methods: with organic solvent and with diluents gas - recirculation of the latter in closed system. The results were justified by HPLC method.
