Euchroma gigantea (Linnaeus, 1758) o “Barrenador gigante metálico de la Ceiba”, es una especie Buprestidae (Insecta: Coleoptera) distribuida en gran parte América. El presente trabajo se realiza con finalidad ampliar el conocimiento distribución geográfica E. Venezuela. Con información recopilada aumenta número estados registrados para país, además incrementan los datos local y a nivel del cont...

Lithospermum erythrorhizon cell cultures have been used to produce plant secondary metabolites, as well as in biosynthetic studies. Shikonin, a representative secondary metabolite of L. erythrorhizon, was first produced industrially by dedifferentiated cell cultures in the 1980s. This culture system has since been used in research on various plant secondary metabolites. Other boraginaceaeous pl...

A phytochemical investigation of the least polar organic extracts of Arnebia hispidissima (Lehm.) DC. roots has led to the isolation of two unique polycyclic geranylhydroquinone-derived metabolites, arnebacene (1) and arnebidin (2), along with some known phenolic metabolites viz., arnebin-7 (3) and vanillic acid (4). The chemical identification of the new isolated compounds, including their rel...

background: iran is a land of great heritage of ancient medical scholars. herbal medicines, as a basement of treatment of diseases have been clearly described in the medical texts of these scholars including rhazes, avicenna, and others. numerous plants are introduced in these texts to treat those diseases likely to be infective ones. few attempts have been made to evaluate ethnopharmacological...

Cell culture in shake flask and air-lift bioreactor was carried out to exploit the potential of Arnebia sp. for napthoquinone metabolite production. Cell suspension cultures of Arnebia were established from friable callus in liquid MS medium supplemented with 6-benzylaminopurine (BAP) (10 μM) and indole-3-butyric acid (IBA) (5 μM). Growth kinetic studies were done by using settled cell volume a...
