  • Estimated concentrations of monoterpene metabolites within glandular cells (bottom row) derived from the monoterpene content of isolated peppermint gland cell clusters (from McCaskill et al., 1992; top row) and an estimated volume of 4.5 × 10−5 μm for an eight-celled disk of secretory cells (gland cell cluster) from a typical peppermint peltate trichome. n.d., Not detectable.
