Duroia saccifera: in vitro germination, friable calli and identification of β-sitosterol and stigmasterol from the active extract against Mycobacterium tuberculosis
Abstract:Duroia saccifera (Rubiaceae) occurs in the Amazon rainforest and their extracts showed antibacterial properties. To obtain greater quantities of active substances, leaf segments from in vitro D. saccifera seedlings were used as explants for calli induction; calli were multiplied via multiple subcultures, dried and extracted with hexane followed by ethyl acetate (EtOAc) and methanol (MeOH). As D. macrophylla had been reported to produce antimycobacterial substances, we assayed calli extracts against Mycobacteri… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
