The contents of iridoid glycosides penstemide and serrulatoloside were determined with HPLC method in callus and cell cultures, plants regenerated with tissue culture method and in the intact plants of Penstemon serrulatus Menz.
A plating method is described for cultured cells of Penstemon serrulatus Menz. which allows effective cloning of aggregates consisting of less than 10 cells, on a simple synthetic medium. The obtained clones snowed high diversity with respect to their ability to produce penstemide, an ester iridoid
From leaves of PENSTEMON CONFERTUS Dougl. a valeriana-type ester iridoid has been isolated and structurally elucidated as dihydropenstemide by spectroscopic methods. Catalytic hydrogenation of penstemide provides a new compound, identified as 8- EPI-dihydropenstemide.
Penstemide and serrulatoloside as well as penstemide aglycone and serrulatoloside aglycone were isolated and identified in the calli and suspension cultures of Penstemon serrulatus. The influence of serrulatoloside, penstemide, and its aglycone on the spontaneous proliferation of mouse spleen
BACKGROUND
Penstemon gentianoides (Kunth) Poir. and Penstemon campanulatus (Cav.) Willd. (Plantaginaceae) are important medicinal plants in Mexico used by indigenous people for their anti-inflammatory effects and to also reduce rheumatic pains.
OBJECTIVE
In addition to radical scavenging activity,
