goniothalamus tenuifolius/fever

Goniotetracin and a mixture of (2,4-cis and trans)-gonioneninone, new, bioactive, mono-tetrahydrofuran (THF) gamma-lactone and ketolactone acetogenins, were isolated from the bark of Goniothalamus giganteus (Annonaceae) by activity-directed fractionation using the brine shrimp lethality test (BST).

Goniotricin (1) and a mixture of (2,4-cis and -trans)-xylomaticinones (2), new bioactive annonaceous acetogenins, were isolated from the bark of Goniothalamus giganteus (Annonaceae) by activity-directed fractionation using the brine shrimp lethality test. Compound 1 is the first nonadjacent

Two new acetogenins, (2,4-cis and trans)-gigantecinone (1), isolated as a mixture, and 4-deoxygigantecin (2), a known acetogenin whose absolute stereochemistry has not been determined previously, were isolated using activity-directed fractionation, from the bark of Goniothalamus giganteus. A key

4-Deoxyannomontacin (1) and a mixture of (2,4-cis and trans)-annomontacinone (2), new bioactive mono-tetrahydrofuran (THF) gamma-lactone and keto-lactone acetogenins, respectively, as well as five known mono-THF acetogenins [xylomaticin, longifolicin, longicoricin, (2,4-cis and

Seven Malaysian medicinal plants were screened for their antiplasmodial activities in vitro. These plants were selected based on their traditional claims for treatment or to relieve fever. The plant extracts were obtained from Forest Research Institute Malaysia (FRIM). The antiplasmodial activities
