In a supercritical fluid workflow, CO2 with or without the addition of an organic
modifier, is used to extract (SFE) and purify (SFC) target compounds. The CO2 used
as a solvent is safe and the extracts produced by this process are free from biological
contaminants, have longer shelf life, high potency, and address major international
concerns regarding residual solvent concentration.2 In this study, a complete SFE-SFC
workflow will be demonstrated using the MV-10 ASFE system (MV-10) for extraction and
the Prep 80a SFC System (SFC 80) for purification of two compounds; vanillin from
vanilla planifolia and cinnamic acid from Cinnamomum Verum. This workflow includes
SFE method development, analytical method development, scale-up, purification, and
fraction analysis. The process can be adapted to purify target compounds from a variety
of natural products and matrices.
