    Antibacterial activity and cytotoxicity of extractives from Uvaria hamiltonii stem bark.[Pubmed: 12628415]

    METHODS AND RESULTS:
    The extracts as well as piperolactum C, goniopedaline, 6beta-hydroxystigmasta-4,22-dien-3-one(6-Hydroxystigmasta-4,22-dien-3-one ) and a mixture of cis- and trans-4-hydroxymelleins obtained from Uvaria hamiltonii stem bark exhibited mild to moderate in vitro antibacterial activity.
    CONCLUSIONS:
    The results obtained were compared with a standard antibiotic, kanamycin. In a brine shrimp lethality bioassay the pet-ether, dichloromethane, methanol extracts and a major alkaloid, piperolactum C were found to exhibit mild to moderate cytotoxicity.

    Radical scavenging activity of triterpene steroids from stem of Polygonum pulchrum Bl[Reference: WebLink]

    METHODS AND RESULTS:
    Four triterpene steroids; namely, (1) 6Î2-hydroxystigmasta-4,22-dien-3-one(6-Hydroxystigmasta-4,22-dien-3-one ), (2) stigmasterol,(3) stigmasta-4,22-dien-3-one, and (4) ergosterol peroxide, were isolated and identified from stems of P. pulchrum Bl. The antioxidant activities of all compounds were indicated by IC50 value of the compounds. The values of IC50 (μM) of6 Î2-hydroxystigmasta-4,22-dien-3-one, stigmasterol, Stigmasta-4,22-dien-3-on,ergosterol peroxide, and vitamine C (standard) toward DPPH were obtained at 233.4 ± 0.28; 372.3 ± 0.33; 144.80 ± 0.24; 1083.1 ± 0.38; and 68.9 ± 0.12, respectively.
    CONCLUSIONS:
    We found that Stigmasta-4,22-dien-3-onewas the most active compound toward DPPH.

    Chemical constituents from Hedyotis diffusa.[Pubmed: 19624011]

    METHODS AND RESULTS:
    The compounds were isolated and purified by various chromatographic techniques and identified by their physicochemical properties and spectral data. Eight compounds had been reported in last paper, and this time eight more compounds were isolated and identified as 6-Hydroxystigmasta-4,22-dien-3-one (1), 3-hydroxystigmasta-4,22-dien-7-one (2), 2-hydroxy-3-methylanthraquinone (3), 2,6-dihydroxy-3-methyl-4-methoxyanthraquinone (4), iso-scutellarein (5), isoetin (6), aesculetin (7), gypsogenic acid (8).
    CONCLUSIONS:
    Compounds 1-3, 5-8 were obtained from the genus Hedyotis for the first time.
