Juniperus sabina L. is normally low shrub with procumbent or obliquely ascending branches, or rarely a small tree to about 4 m, monoecious or dioecious. Juniperus sabina L. is a medicinal plant used in folk medicine as an abortive. Its lignanes  have antineoplastic and antiviral activity, and also essential oil of Juniperus sabina L. has shown antibacterial a...

The genus Juniperus (Cupressaceae) consists of approximately GO species distributed in the orthern Hemisphere, except for J.yrocera Hocll. which extends into the Southern Hemisphere in Africa (Florin, 1963). The delimitation of the species of Juniperus is difficult in all of the world; few taxonomic studies have encompassed any large geographical or natural province. Gaussen (1968) lists 99 spe...

The quassinoids are a group of complex, highly oxygenated, degraded triterpene mostly found in Simaroubaceae family. Two quassinoids (degraded triterpenes), 1 and 2 were isolated first time from the stem bark of Ailanthus excelsa. Compound 1 is C19 quassinoid. C19 quassinoid derived biogenetically from a C20 quassinoid, via a 1,2 – dioxo derivative. The structural elucidation is based on the an...

Cyperus rotundus, Caesalpinia bonducella, Tinospora cordifolia, Gardenia gummifera, Ailanthus excelsa, Acacia arabica, Embelia ribes and Ventilago maderspatana from Melghat forest were screened for their antibacterial potential against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Proteus vulgaris, Salmonella typhi, Shigella flexneri, Salmonella paratyphi, Salmonella typhimuri...

Background Amazonian upland forests are expansive and can comprise large continuous tracts. There have been several studies on the population genetic structure of species in this kind of forest, but there are few studies that aim to understand genetic structure throughout the Amazon [1]. The Brazil-nut tree, Bertholletia excelsa, is a monotypic genus, endemic to upland forests and distributed a...

Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. hemispherica J. & C. Presl, J. communis var. megistocarpa Fern. & St. John, J. c. var. nipponica (Maxim.) Wils., J. c. var. oblonga hort. ex Loudon and J. c. var. saxatilis Pall. were sampled and DNA fingerprinting (RAPDs, Random Amplified Polymorphic DNAs) was performed. Based on 191 RAPD bands, there was litt...
