The content of the two marker constituents in rhizomes and leaves of P. kurroa growing in different locations was also analysed, demonstrating that all of these phytochemicals in the target plant are interestingly dependent of the locality.
However, in some instances we observed associations with sources but not with their marker constituents.
Analysis with PMF may detect associations for sources when marker constituents do not, or vice versa (Ito et al. 2004).
To analyze terpene lactones as pharmacokinetic marker constituents of EGb 761®, the supernatant plasma was transferred into two polypropylene tubes, acidified with hydrochloric acid (to stabilize terpene lactones), and stored <−20°C until analysis.
If nerve fibres in skin retract or 'degenerate' to the depth at which mitochondrial function was preserved, it is expected that markers for any constituent of those fibres will show reductions.
Based on chemical profiles, and isolation and identification of major marker compounds (new propolis constituents), new plant sources of propolis were found: Azadiracta indica (neem tree) and Acacia spp. (most probably A. nilotica).
If not all the active compounds are known or pharmacological activity of the product is caused by synergistic effect of all its constituents, some marker compounds must be used for standardization purposes.
50 Enhanced liver fibrosis (ELF) panel employs automated immunoassay of three serum markers of matrix constituents and mediators of matrix remodeling (hyaluronic acid, amino-terminal propeptide of type III collagen, and tissue inhibitor of matrix metalloproteinase 1).
Usually, it is a result of considering the parameters of head constituent, dependent daughter, role marker, and phrasal/sentential pattern.
The outcome of this study was that a constituent of the surgical marker pen causes cell and tissue death in culture, implying the same would occur in vivo.
