Sarracenin is an iridoid found in several plant species in the carnivorous family Sarraceniaceae.[1] It also occurs in other non-carnivorous plants such as Strychnos spinosa (Loganiaceae)[2] and Patrinia heterophylla (Caprifoliaceae).[3]
History
Sarracenin was first isolated from the roots of Sarracenia flava in 1976. Analysis of S. flava extracts was prompted by their use as a folk remedy by people of the Okefenokee swamp region[4]
Biosynthesis
Sarracenin is believed to be derived from loganin, with either morronoside or secologanin serving as intermediates in the biosynthetic process.[4]
Uses
Sarracenin displays antimicrobial activity against several pathogens including Staphylococcus aureus, Streptococcus pyogenes, Shigella dysenteriae, Klebsiella pneumonia, Candida albicans, Candida tropicalis, Candida thrusei, and Candida stellatoidea[2]. It has also demonstrated cytotoxicity against three tumor cell lines: A375 (human melanoma cell), SGC-7901 (human gastric cancer cell), and HeLa.[3]
Ecology
Sarracenin is the primary volatile present in the insect-attracting spoons of Heliamphora species. When Heliamphora plants were grown in a laboratory setting, sarracenin was rarely present in these spoons. Plants that did produce sarracenin generally attracted more insects than those without, suggesting a role in prey attraction or capture.[5] Sarracenin is also present in the pitchers and lids of Darlingtonia californica and many Sarracenia species, likely serving the same purpose as in Heliamphora.[1]
