  1. Chemical components of the roots of Noni (Morinda citrifolia) and their cytotoxic effects.

    Fitoterapia 82(4):704 (2011) PMID 21356281

    Roots of Morinda citrifolia (Noni or Yor in Thai) have been used traditionally for thousands of years to treat chronic diseases such as cancer and heart disease. In this study, three new anthraquinones together with 15 known compounds were isolated from the roots of M. citrifolia (Rubiaceae). Their s...
  2. Protective effect of Spirulina fusiformis on chemical-induced genotoxicity in mice.

    Fitoterapia 75(1):24 (2004) PMID 14693216

    Spirulina fusiformis given by oral route to mice at doses of 250, 500 and 1000 mg kg(-1) significantly inhibit the genotoxicity induced by cisplatin and urethane. In addition, a significant reduction in the extent of lipid peroxidation with concomitant increase in the liver enzymatic (GPx, GST, SOD,...
  3. Antimicrobial activity of Psychotria microlabastra.

    Fitoterapia 72(7):818 (2001) PMID 11677022

    The methanol extracts of leaves, root and stem barks of Psychotria microlabastra showed a broad spectrum of antibacterial activity, that was increased on fractionation (petrol, dichloromethane, ethyl acetate), particularly in the ethyl acetate fractions. None of the extractives showed activity again...
  4. Constituents from Salvia triloba.

    Fitoterapia 72(7):850 (2001) PMID 11677033

    Twelve hydrocarbons, four sterols, three triterpenes, nineteen fatty acids, two phenolic acids, and five flavonoids have been detected and identified in Salvia triloba. Among the isolated flavonoids, 8-methoxygenistein 7-O-alpha-L-rhamnoside 4'-O-beta-D-glucoside (1), is reported for the first time....
  5. Barbarea verna as a source of 2-phenylethyl glucosinolate, precursor of cancer chemopreventive phenylethyl isothiocyanate.

    Fitoterapia 72(7):760 (2001) PMID 11677014

    The isolation of gram-amounts of 2-phenylethyl glucosinolate (gluconasturtiin, GST) from Barbarea verna seeds is reported for the first time. This vegetable source was of crucial importance to isolate GST with a high purity grade and in high yield. Indeed, B. verna seeds contain GST as the only gluc...
  6. A new norneohopane caffeate from Filicium decipiens.

    Fitoterapia 72(7):737 (2001) PMID 11677010

    Investigation of the dichloromethane extract of the stem of Filicium decipiens yielded a new natural product, 24-norneohopa-4(23),22(29)-diene-3beta,6beta,7beta-triol 7-caffeate (1).
  7. A xanthone from Shultesia guianensis.

    Fitoterapia 72(6):715 (2001) PMID 11543979

    The isolation of 1-hydroxy-3,7-dimethoxyxanthone (1) from Shultesia guianensis is reported along with relevant NMR spectra, including new data by two-dimensional NMR experiments (HMQC and HMBC).
  8. Cyclopeptide alkaloids from Zizyphus jujuba.

    Fitoterapia 72(5):507 (2001) PMID 11429244

    A new cyclopeptide alkaloid, jubanine-C (1), together with known alkaloids scutianine-C (4) and zizyphine-A (5), have been isolated from the stem bark of Zizyphus jujuba and identified by spectral analysis.
  9. Antifungal compounds from turmeric and nutmeg with activity against plant pathogens.

    Fitoterapia 99:341 (2014) PMID 25173461

    The antifungal activity of twenty-two common spices was evaluated against plant pathogens using direct-bioautography coupled Colletotrichum bioassays. Turmeric, nutmeg, ginger, clove, oregano, cinnamon, anise, fennel, basil, black cumin, and black pepper showed antifungal activity against the plant...
  10. Synthesis and antimycobacterial evaluation of natural oridonin and its enmein-type derivatives.

    Fitoterapia 99:300 (2014) PMID 25316557

    A series of enmein-type derivatives were synthesized and assayed for their antimycobacterial effects. The structures of the synthesized compounds were established by (1)H NMR, (13)C NMR and mass spectral analysis. All the compounds were screened for their antimycobacterial properties against Mycobac...
