Abstract Peroxides are an interesting group among biological active natural compounds. These metabolites contain a peroxide group (-O-O-) in which each oxygen atom is bonded to the other oxygen and to another atom. β-Oxygen in hydroperoxide group is considered as more active. Present review describes research on more than 230 natural peroxides isolated from plants, algae, and fungi. Intensive searches for new classes of biologically active metabolites produced by terrestrial and marine origin have resulted in the discovery of dozens of compounds possessing high antimalarial, antibacterial, cytotoxic, and other pharmacological activities as an important source of leads for drug discovery.

Hypericum also displays an ample variety of other biological actions, such as hypotensive, analgesic, anti-infective, anti-oxidant, and spasmolytic abilities. However, recent investigations highlighted that this species could be advantageous for the cure of other pathological situations, such as trigeminal neuralgia, as well as in the treatment of cancer. This review focuses on the in vitro and in vivo antitumor effects of St. John’s Wort (Hypericum perforatum), its derivatives, and other Hypericum species in hematologic malignancies.

  • Hypericum Scruglii Bacchetta, Brullo & Salmeri, Is It a Possible Natural
    Hypericum scruglii Bacchetta, Brullo & Salmeri, is it a possible natural resource against Fibromyalgia? Mauro Giovanni Carta, Maria Manconi, Gianluigi Bacchetta, Germano Orrù, Maria Cristina Deiddda, Mario Musu, Gabriele Finco, Abstract Background Fibromyalgia (FM) is today a serious public health issue. Tested treatments have shown limited efficacy. Oxidative stress probably interacting with the glutamatergic / gamma - Aminobutyric acid balance may play a role. Antidepressants improve sleep and mood especially those with double action on serotonin and norepinephrine, but these are also those with a greater risk of manic switch considering the high frequency of comorbidity with bipolar disorders. Methods This narrative review tries to evaluate, on the basis of in vitro and animal studies, the potential utility in fibromyalgia of Hypericum Scruglii, an endemic species peculiar to the island of Sardinia. Results The studies that have verified the antidepressant efficacy of Hypericum Perforatum and the first attempts of its use in fibromyalgia are reported as well as the studies that found the phloroglucinol derivatives from Hypericum longistylum (well-known in traditonal Chinese medicine) that facilitate the differentiation of neural progenitor cells, and increase the efficiency of differentiation into serotonergic neurons. Conclusions The advantage of Hypericum Scruglii may be represented by the anti-oxidant potential revealed to be greater than in other species of the same genus. The paper also describes new approaches to improving the oral bioavailability of very poor water-soluble molecules of hypericum extracts. Introduction Fibromyalgia (FM) is a central sensitization syndrome with around 3% of prevalence in western societies, especially frequent in women [1]. The best-known symptom is chronic widespread pain; other syndromes such as fatigue, anxiety, mood disorders, and dysregulation of biological rhythms with sleep disturbances frequently accompanied by pain [2].

    International Journal of Food Science and Technology 2009, 44, 2249–2255 2249 Original article Antioxidants in aerial parts of Hypericum sampsonii, Hypericum japonicum and Hypericum perforatum Chung Li Chen, Chien Hsiu Huang & Jih Min Sung* Department of Agronomy, National Chung Hsing University, Taichung, Taiwan, 40227, ROC & Department of Biotechnology, Hung Kuang University, Taichung County, Taiwan, 43302 (Received 19 March 2009; Accepted in revised form 14 August 2009) Summary Antioxidants contents and antioxidative enzymes and their activities in fresh aerial tissues of Hypericum sampsonii (Sampson’s St John’s Wort), Hypericum japonicum (Japanese St John’s Wort) and Hypericum perforatum were investigated. Hypericum sampsonii contained more total ascorbate [34.33 lmol g)1 fresh weight (FW)] than H. perforatum (57% less) and H. japonicum (82% less). It also contained more thiol and phenolics than two other species. Hypericum japonicum had highest superoxide dismutase (SOD) activity (8.74 mmol min)1 g)1 FW), followed by H. sampsonii (2% less) and H. perforatum (37% less). Hot-air dried H. perforatum materials contained more thiol [208.7 lmol g)1 dry weight (DW)] and phenolics (352.82 mg g)1 DW) than freeze-dried and fresh materials. Both drying treatments decreased the activities of antioxidative enzymes in aerial tissues of H. perforatum. However, freeze-dried H. perforatum contained the highest SOD activity (5.42 mmol min)1 g)1 DW) among the antioxidative enzymes measured from both freeze-dried and hot-air dried tissues (ranged from 0.02 to 2.65 lmol min)1 g)1 DW). Keywords Antioxidant, drying, Hypericum japonicum, Hypericum perforatum, Hypericum sampsonii.

  • Linnaeus' Philosophia Botanica
    linnaeus’ Philosophia Botanica STEPHEN FREER Stephen Freer, born at Little Compton in1920, was a classical scholar at Eton and Trinity College Cambridge. In 1940, he was approached by the Foreign Office and worked at Bletchley Park and in London. Later, Stephen was employed by the Historical Manuscripts Commission, retiring in 1962 due to ill health. He has continued to work since then, first as a volunteer for the MSS department of the Bodleian Library with Dr William Hassall, and then on a part-time basis at the Oxfordshire County Record. In 1988, he was admitted as a lay reader in the Diocese of Oxford. His previous book was a translation of Wharton’s Adenographia, published by OUP in 1996. A fellow of the Linneau Society of London, Stephen lives with his wife Frederica in Gloucestershire. They have a daughter, Isabel. COVER ILLUSTRATION Rosemary Wise, who designed and painted the garland of flowers on the book cover, is the botanical illustrator in the Department of Plant Sciences in the University of Oxford, associate staff at the Royal Botanic Gardens, Kew, and a fellow of the Linneau Society of London. In1932 Carl Linnaeus made an epic journey to Lapland, the vast area across arctic Norway, Sweden, and Finland. In 1988, to mark the bicentenary of the Linneau Society of London, a group from Great Britain and Sweden retraced his route. Rosemary, was the official artist and the flowers featured here are taken from ones painted at that time, plants with which Linnaeus would have been familiar. The garland of flowers surrounds an image of the medallion portrait of Linnaeus by C.
