Pressurized liquid extraction of medicinal plants

The suitability of pressurized liquid extraction (PLE) in medicinal plant analysis was investigated. PLE extracts from a selection of representative herbs were compared with extracts obtained according to Pharmacopoeia monographs with respect to yield of relevant plant constituents, extraction time...

Summary:The suitability of pressurized liquid extraction (PLE) in medicinal plant analysis was investigated. PLE extracts from a selection of representative herbs were compared with extracts obtained according to Pharmacopoeia monographs with respect to yield of relevant plant constituents, extraction time and solvent consumption. In all cases a significant economy in time and solvents was realized, while extraction yields of the analytes were equivalent or higher.
