Molluscicidal and Piscicidal activities of Venezuelan Chrysobalanaceae Plants
No full textExtracts of increasing polarity of 6 Venezuelan plants belonging to the Chrysobalanaceae family were tested for possible letal:toxicity against Biomphalaria glabrata Say, a snail intermediate hosts of Schistosoma mansoni Sambon. The piscicidal toxicity of the active extracts was also evaluated with the aim of findings compounds without toxicity in nontarget organisms, principally fishes and humans
Myricetin glycosides from Licania densiflora
No full textDried leaves of Licania densiflora yielded five myricetin glycosides: myricetin 3′-methylether-3-O-glucoside (1), myricetin 3′-methylether-3-O-galactoside (2), myricetin 4′-methylether-3-O-rhamnoside (3), myricetin 3′,5′-dimethylether-3-O-glucoside (4), and myricetin 3′,5′-dimethylether-3-O-rhamnoside (5). Their structures were elucidated by spectroscopic methods including mono- and bi-dimensional NMR techniques
