Latest Development of Matrix Solid Phase Dispersion Extraction and Microextraction for Natural Products from 2015-2021

Matrix solid phase dispersion (MSPD) is a rapid and flexible sample pretreatment method that accomplishes sample disruption, extraction, filtering and purification in one step and is especially suitable for solid, semisolid and viscous samples. More than 30 years have elapsed since it was first proposed, and there are many published reviews. However, there is no review on the use of MSPD to extract active compounds from natural products. In this review, the latest developments from 2015–2021 in MSPD microextraction techniques, including sorbents, elution solvents and assisted MSPD extraction, along with their applications in natural products, are systematically discussed and classified according to the structure of the active constituents, which mainly refer to phenolic acids, flavonoids, alkaloids, anthraquinones and terpenes.
