    Abstract:

    In addition to aucubin, 6beta-hydroxyboschnaloside, and 6-O-(8"-hydroxy-2",6"-dimethyl-2"(E), 6"(E)-octadienoyl)-6beta-hydroxyboschnaloside, the new iridoid glucoside ovatuside has been isolated from the aerial parts of Penstemon ovatus. This iridoid was shown to be 6-O-(8"-hydroxy-2",6"-dimethyl-2"(E),6"(Z)-octadienoyl)-6beta-hydroxyboschnaloside.

    Red Algae

    Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
