Methods: The powdered material was extracted with methanol a soxhlet extractor compounds Evaluation determined zone inhibition disc diffusion method. Results: Three were isolated from chromatography, namely...

Achillea tenuifolia Lam. (Asteraceae) afforded a methanolic extract from which after fractionation in solvents with different polarities, two known flavones 3', 5- dihydroxy- 4', 6, 7- trimethoxy flavone (eupatorine, compound 3), 5- hydroxy- 3',4', 6, 7- tetramethoxyflavone (compound 4), besides stearic acid (compound 1), lupeol (compound 2), daucosterol (β- sitosterol 3-O- β- D- glucopyranosid...

The effect of four sub-extracts prepared from the lyophilized hydroalcoholic bark of Dipteryx alata (Leguminosae-Papilionoideae) dissolved in a methanol-water (80:20) mixture through a liquid-liquid partition procedure has been investigated against the neuromuscular blockade of the venom of the snake Bothrops jararacussu. The active CH₂Cl₂ sub-extract has been extensively analyzed for its chemi...

New clerodane diterpenes, 12-epi-megalocarpodolide D (2) and an epimeric mixture of crotonolins A (3) and B (4), were isolated from the bark of Croton oligandrus following a bioassay-guided isolation protocol. Known compounds, megalocarpodolide D (1), 12-epi-crotocorylifuran (5), cluytyl-ferulate (6), hexacosanoyl- ferulate (7), vanillin (8), acetyl-aleuritolic acid (9) and lupeol (10), were al...

Bioassay-guided fractionation of an EtOAc extract of the stem wood of Euphorbia quinquecostata using a phorbol dibutyrate receptor-binding assay system as a monitor yielded four inhibitory isolates (1-4), inclusive of one new compound, 17-hydroxyingenol 20-hexadecanoate (1), and three previously known compounds, ingenol 20-hexadecanoate (2), ent-16 alpha,17-dihydroxyatisan-3-one (3), and ent-3 ...
