The accurate structure determination of strigolactones (SLs) that are produced by plants leads to the precise understanding of the biosynthesis and functions of their molecules. SLs need to be isolated and purified from the plant roots or root exudates in a hydroponic solution using appropriate methods in order to determine the structures. In this chapter, we describe a small-scale extraction method for chromatographic analysis of known SLs and a large-scale purification method for isolation of unknown SLs, together with methods for the hydroponic culture of plants and collection of root exudates. Finally, we present spectroscopic data that are helpful in identifying SLs.
