Ranarivelo, 2017 1 ABSTRACT Psorospermum belongs to the tribe Vismieae (Hypericaceae). Morphologically, Psorospermum is very similar to Harungana, which also belongs to Vismieae along with another genus, Vismia. Interestingly, Harungana occurs in both Madagascar and mainland Africa, as does Psorospermum; Vismia occurs in both Africa and the New World. However, the phylogeny of the tribe and the relationship between the three genera are uncertain.
  • Variability of Hypericins and Hyperforin in Hypericum Species from the Sicilian Flora

    Variability of Hypericins and Hyperforin in Hypericum Species from the Sicilian Flora

    Chemistry & Biodiversity, Volume17, Issue1, January 2020, e1900596 Variability of Hypericins and Hyperforin in Hypericum Species from the Sicilian Flora Silvia Lazzara, Alessandra Carrubba, Edoardo Napoli Abstract Within Sicilian flora, the genus Hypericum (Guttiferae) includes 10 native species, the most popular of which is H. perforatum. Hypericum’s most investigated active compounds belong to naphtodianthrones (hypericin, pseudohypericin) and phloroglucinols (hyperforin, adhyperforin), and the commercial value of the drug is graded according to its total hypericin content. Ethnobotanical sources attribute the therapeutic properties recognized for H. perforatum, also to other Hypericum species. However, their smaller distribution inside the territory suggests that an industrial use of such species, when collected from the wild, would result in an unacceptable depletion of their natural stands. This study investigated about the potential pharmacological properties of 48 accessions from six native species of Hypericum, including H. perforatum and five ‘minor’ species, also comparing, when possible, wild and cultivated sources. The variability in the content of active metabolites was remarkably high, and the differences within the species were often comparable to the differences among species. No difference was enlightened between wild and cultivated plants. A carefully planned cultivation of Hypericum seems the best option to achieve high and steady biomass yields, but there is a need for phytochemical studies, aimed to identify for multiplication the genotypes with the highest content of the active metabolites. Introduction According to the available literature, 10 Hypericum species have been identified in Sicily: H. aegypticum L., H. androsaemum L., H. australe TEN., H. hircinum L., H. perfoliatum L., H. perforatum L., H. pubescens BOISS., H.

Article History: Received: 04 December 2016 /Accepted in revised form: 15 March 2017 © 2013 Iranian Society of Medicinal Plants. All rights reserve Abstract Hypericum perforatum L. (St. Johns’ wort) is the most commercially important species of the genus Hypericum and contains a wide range of components including naphthodianthrones, phloroglucinols, tannins, xanthones, phenolic acids and essential oil. In order to establish an efficient protocol for regeneration, the effects of explant type and plant growth regulators on direct and indirect shoot regeneration in H. perforatum were evaluated. According to obtained results the media supplemented with 0.1 mg l-1 Benzyl Adenine (BA) was effective for shoot proliferation from shoot tip explants of H. perforatum that showed the highest shoots number (15.5 shoots per explant) and shoot height (2.07 cm). In second experiment a method for rapid micro propagation of H. perforatum through indirect plant regeneration from calli has been developed. The results demonstrated that a combination of auxin and cytokinin was needed for optimum callus induction and leaf segments were suitable explant for callus induction in H. perforatum. Callus induction was observed in most studied treatments but the highest callus volume (1.43 cm3) was obtained by leaf segments in media supplemented with 0.25 mg l-1 2,4- Dichlorophenoxyacetic acid (2,4-D)+1 mg l-1 Kinetin.

The larvae, pupae and adult stages of T. molitor were exposed to different doses of H. perforatum essential oil for 24 h. After exposure, mortality rate, LC50, LC90 and LC99 values, antioxidant enzyme activities [superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST) and glutathione peroxidase (GPx)], acetylcholinesterase (AChE) activity and malondialdehyde (MDA) levels were measured in the insects. Tenebrio molitor was cultured at Gazi University Department of biology and all analyses were done in Yozgat bozok University in 2017 and 2018. The results indicated that the pupae of T. molitor were the most tolerant and adults were the most sensitive. Mortality increased with the increasing concentration of essential oil. Also, increasing doses of essential oil caused decreasing in SOD, CAT, GST GPx and AChE activities and increasing in MDA level. These results indicate that essential oil of H. perforatum can be used against T. molitor in a pest control program. Keywords: Antioxidant enzymes, GC-MS, Hypericum, insecticidal activity, meal worm, pesticide Öz Bu çalışmada, Hypericum perforatum L., 1753 (Malpighiales: Hypericaceae) distilasyonundan elde edilen uçucu yağın, Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae)’ün farklı gelişme dönemleri üzerindeki etkisi test edilmiştir.
