Extraction and Isolation of Natural Organic Compounds from Plant Leaves Using Ionic Liquids.

Extraction and Isolation of Natural Organic Compounds from Plant Leaves Using Ionic Liquids. Adv Biochem Eng Biotechnol. 2018 Nov 16;: Authors: Usuki T, Yoshizawa-Fujita M Abstract Plants contain many kinds of natural organic compounds, and their compounds possess many useful properties. Natural organic compounds are important for the development of medicines, pesticides, fragrances, cosmetics, and synthetic chemicals. In this chapter, we introduce efficient methods for extraction and isolation of valuable natural organic compounds from various plant leaves by using cellulose-dissolving ionic liquids. High-polarity ionic liquids, which can dissolve cellulose, contribute to the extraction of natural organic compounds from plant leaves probably by breaking down plant cell walls, which are composed of cellulose, hemicellulose, and lignin. Extraction and isolation of shikimic acid from ginkgo leaves, caffeoylquinic acids from sweet potato leaves, and neral and geranial (which combine to form citral) from lemon myrtle leaves were performed. Ionic liquids can achieve extraction rates greater than those achieved with water and other organic solvents. Graphical Abstract. PMID: 30443731 [PubMed - as supplied by publisher]
