Veronica longifolia
(NCBI TaxID 165317,
species name lookup)
Taxonomic group: plant / Streptophyta
(Phylum: Streptophyta)
Organ / tissue: leaf
NCBI PubMed ID: 10677081Publication DOI: 10.1016/s0021-9673(99)01170-xJournal NLM ID: 9318488Publisher: Amsterdam; New York: Elsevier

Several methods for the extraction of two iridoid glycosides, catalpol and aucubin, from the plant matrix (Veronica longifolia leaves) were compared. Pressurized hot water extraction and hot water extraction were the most efficient isolation techniques for both. Pressurized liquid extraction and maceration with various organic solvents were also tested. Relative to the amounts extracted with hot water, ethanol extracted only 22% of catalpol and 25% of aucubin and pressurized hot water extracted 83% of catalpol and 92% of aucubin. The lowest relative standard deviations, 22% for catalpol and 8% for aucubin, were achieved with hot water extraction (13 repetitions), and the highest relative standard deviations, 76% for catalpol and 73% for aucubin, with pressurized liquid extraction (five repetitions). A fast capillary electrophoretic method was developed for the quantitative determination of catalpol and aucubin.
