    Identification of minor secondary metabolites from the latex of Croton lechleri (Muell-Arg) and evaluation of their antioxidant activity.[Pubmed: 18596648]
    Dragon's blood (Sangre de drago), a viscous red sap derived from Croton lechleri Muell-Arg (Euphorbiaceae), is extensively used by indigenous cultures of the Amazonian basin for its wound healing properties. The aim of this study was to identify the minor secondary metabolites and test the antioxidant activity of this sustance. A bioguided fractionation of the n-hexane, chloroform, n-butanol, and aqueous extracts led to the isolation of 15 compounds: three megastigmanes, four flavan-3-ols, three phenylpropanoids, three lignans, a clerodane, and the alkaloid taspine. In addition to these known molecules, six compounds were isolated and identified for the first time in the latex: blumenol B, blumenol C, 4,5-Dihydroblumenol A, erythro-guaiacyl-glyceryl-beta-O-4'- dihydroconiferyl ether, 2-[4-(3-hydroxypropyl)-2-methoxyphenoxy]-propane-1,3-diol and floribundic acid glucoside. Combinations of spectroscopic methods ((1)H-, (13)C- NMR and 2D-NMR experiments), ESI-MS, and literature comparisons were used for compound identification. In vitro antioxidant activities were assessed by DPPH, total antioxidant capacity and lipid peroxidation assays. Flavan-3-ols derivatives (as major phenolic compounds in the latex) exhibited the highest antioxidant activity.

    [Chemical constituents from stems of Brucea mollis and their cytotoxic activity].[Pubmed: 24199564]
    Ten compounds were isolated from the stems of Brucea mollis by various chromatographic techniques such as column chromatography on silica gel and Sephadex LH-20, and preparative HPLC, and their structures were elucidated as deacetylated isobrucein B (1), indaquassin X (2), cleomiscosin A (3), cleomiscosin B (4), (+)-lyoniresinol (5), (+)-epipinoresinol(6), (+)-pinoresinol (7), (+)-syringaresinol (8), 4,5-Dihydroblumenol A (9) and adenosine (10) on the basis of spectroscopic data analysiS. All compounds were obtained from this plant for the first time, moreover, compound 1 was a new natural product. Compound 2 showed significant cytotoxic activities against the human cell lines HT-29, HepG2, BGC-823 and SKOV3 with IC50 values of 0.84-3.97 micromol x L(-1).

    Antivirus constituents from Alternanthera philoxeroides.[Reference: WebLink]
    To investigate the anti-HBV constituents from Alternanthera philoxeroides.Methods The constituents were isolated with silica gel and gel permeation chromatography,and purified by HPLC.Their structures were elucidated by spectroscopy.The antivirus effects of the isolated compounds were tested by ELISA method in vitro.Results Ten compounds were isolated and elucidated as followings:oleanolic acid(Ⅰ),oleanolic acid 3-O-β-D-glucuronopyranoside(Ⅱ),oleanolic acid 28-O-β-D-glucopyranoside(Ⅲ),chikusetsusaponin Ⅳ a methyl ester(Ⅳ),4,5-dihydroblumenol(Ⅴ),N-trans-feruloyl 3-methyldopamine(Ⅵ),N-trans-feruloyl tyramine(Ⅶ),3β-hydroxystigmast-5-en-7-one(Ⅷ),24-methylenecycloartanol(Ⅸ),and cycloeucalenol(Ⅹ).The values of inhibition percent of compounds Ⅰ-Ⅲ,Ⅴ-Ⅶ revealed a significant distinction compared to the control group.Compounds Ⅱ and Ⅴ showed significant inhibition against HepG2 cells transected with cloned hepatitis B virus DNA,their inhibitive ratios were 85.38% and 87.37% at 50 μg/mL,respectively.Conclusion Compounds Ⅳ-Ⅶ are isolated from this plant for the first time and phenolic amides have been determined as the new structure type from the plants of Alternanthera Forsk.Compounds Ⅱ and Ⅴ from A.philoxeroides show the more significant anti-HBV activities.
