H. perforatum finds huge applications in herbal medicine to treat depression, skin injuries, burns, and neuralgia since antiquity (Grigson, 1958, p. 83; Coffey, 1993, p. 64). Commonly known as St John's Wort, Hypericum perforatum L. is a member of the Hypericaceae family. Joachim SchrÃ¶der, in Comprehensive Natural Products Chemistry, 1999, Xanthones are a group of natural products with interesting pharmaceutical properties,97â101 and the majority occur in two plant families (Gentianaceae and Hypericaceae).97,102,103 Feeding experiments indicated that the xanthone ring system was synthesized from shikimate-derived pre-cursors and via the acetate/malonate route (see Sultanbawa102 for review). Hyperici herba, as used in pharmacopeias, refers to the dried aerial parts, generally in the flowering stage, of H. perforatum (WHO, 2002). The stings are frequently a short-term irritant, but contact with some species can cause pain or numbness that lasts for several days. The translucent glands and surrounding tissues contain the phytochemical hyperforin (Soelberg et al., 2007). The generation of ROS leads to lipid peroxidation and membrane damage and therefore hypericin and similar sensitizers of 1O2 are highly phototoxic.133â135 Other examples of phototoxic polyphenols, whose toxicity may be related to the production of ROS, are the naphthodianthrone fagopyrin (105) from buckwheat (Fagopyrum spp. Meaning: The family is an intimate domestic group made up of people related to one another by bonds of blood, sexual mating or legal ties.

The androecium in composed of ten to many polydelphous stamens. The implication of St John's Wort therapy in diabetic patients suffering from depressive moods, sleeping disturbances, and cognitive deficits also came from comparative studies on experimental animals treated with either insulin or the extract (125 and 250Â mg/kg, for 7 days) for seven days (Can et al., 2011). 26.31. It has been documented that the great Greek physician Hippocrates, known as the Father of Modern Medicine had prescribed the plant to his patients (Adams, 1891). Genera in Hypericaceae. Its common medicinal application for centuries was, however, related to the claimed benefit of the tincture or teas to treat anxiety, depression, and insomnia-related disorders.

Ovary cross-section, showing 3 carpels with parietal placentation, the placentae appressed in the center. Hyperforin, a phloroglucinoid, is now believed to be responsible for the plant's action due to its ability to inhibit serotonin, noradrenaline, and dopamine reuptake, thus increasing their concentration in the synaptic cleft. Se extiende desde las regiones templadas hasta los trÃ³picos. Fig. Name . Robert W. Coppock, Margitta Dziwenka, in Nutraceuticals, 2016. 29.17. The hypericum IL-160 (Lichtwer Pharma, Germany) is manufactured with 80% methanol in a solvent-to-herb ratios of 4:1 to 7:1 and standardized on 0.3% (wt/wt) content of hypericin (Castor et al., 2001). FIGURE 8.36. 12.2) produces (+)-hyperforin, possibly as its major nonnitrogenous secondary metabolite (Erdelmeier, 1998, p. 2). The dark glands in the leaf and other parts of the plant contain hypericin and pseudohypericin (Zobayed et al., 2006). Then, 2,3â²,4,6-tetrahydroxybenzophenone metabolite is further converted into prenylated xanthones such as rubraxanthone (90) and psorospermin (91), which exhibit significant antibacterial and antitumor activities, respectively, and glycosylated derivatives such as acetylcholinesterase inhibitors swertianolin (94) and its precursor bellidifolin (95).79â81. The most prevalent application of St John's Wort extract today in traditional and as over the counter medicine is for the treatment of patients with mild to moderate depression. G. Stamen fascicle removed from flower. B. Vegetative shoot, showing simple, entire, opposite leaves. For example, BPS from H. androsaemum catalyzes the biosynthesis of 2,4,6-trihydroxybenzophenone (12) by condensation of benzoyl-CoA (11) starter with three molecules of malonyl-CoA (1). Rica en aceites y resinas de color amarillo intenso, usadas como colorantes (gutagamba). Hypericaceae Juss. H. perforatum Linn.

(Hypericaceae). Hypericaceae were treated as Guttiferae-Hypericoideae in my , to which the reader is referred for references of work published before 1965. The stamens are [5â] â, centrifugal, often fasciculate in 3â5 bundles. Beyond these CNS effects, recent studies also showed antidiabetic and antiobesity properties suggesting that the extract may be employed to treat metabolic disorders. Hypericaceae, Hypericum canariense illustrated. The reaction to the benzophenone (10) was confirmed in vitro with a partially purified protein preparation incubated with 3-hydroxybenzoyl-CoA (9) and malonyl-CoA;106 the second ring closure to the xanthone (11) apparently requires an additional enzyme. numerous, centrifugal stamens often fasciculate, and a superior, syncarpous, 3–5 carpellate ovary, the fruit a capsule (usually), berry, or drupe.
