A robust analysis of Juniperus, sect. Juniperus is presented based on nrDNA and five cpDNA regions. The section is clearly divided into two groups composed of blue and red seed cone species and is composed of four major clades: J. communis and allies; J. cedrus oxycedrus allies; J. brevifolia deltoides navicularis; and a loose clade of J. formosana, f. var. mairei, and J. communis var. jackii. ...

The genus Juniperus L. (Cupressaceae), an aromatic evergreen plant, consists of up to 68 species around the world. We classified five species of Juniperus found in Iran using molecular markers to provide a means for molecular identification of Iranian species. Plants were collected (three samples of each species) from two different provinces of Iran (Golestan and East Azarbayejan). The DNA was ...

Analyses of individuals classically treated as Juniperus oxycedrus L. var. oxycedrus from Morocco, Portugal, Spain, France, Italy, Greece and Turkey, using DNA sequencing of nrDNA (ITS 1, 5.8S, ITS 2) plus RAPDs, leaf terpenoids and morphology revealed that two cryptic, genetically distinct but morphologically almost identical species are present. These species, J. oxycedrus L. var. oxycedrus a...

A hydrocarbon that is widespread in Juniperus foliage was isolated from Juniperus erectopatens (Cheng and L. K. Fu) R. P. Adams and identified as (E,E,E)-1,7-dimethylcyclodeca-1,4,7-triene (pregeijerene B). Geometry of the disubstituted double bond was determined by IR and NMR spectroscopy, while that of the trisubstituted double bonds was proven by comparison of the products of selective hydro...

Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. jackii Rehdr, J. c. var. saxatilis Pall. were sampled and SNPs from nrDNA were examined. Based on these data and previous data, a new variety of J. communis is recognized: Juniperus communis var. charlottensis R. P. Adams, var. nov. It occurs in muskeg bogs on Queen Charlotte Island, British Columbia and in the...

Junipers (Juniperus spp.) are native woody shrubs that have expanded beyond their normal historical ranges in the western and southwestern United States since the late 1800s. Most ecologists and resource managers agree that juniper has become a deleterious native invasive plant that threatens other vegetation ecosystems, such as grasslands, through a steady encroachment and ultimate domination....

fruit and leaves of junipers are commonly used internally as tea and pounded fruits are eaten to lower blood glucose levels in anatolia. thus, we aimed to evaluate antidiabetic and antioxidant potential and the chemical profile of juniperus foetidissima willd. and j. sabina l. in this study. in-vitro antidiabetic activities of leaf and fruit extracts were examined by their inhibitory activity o...

Since the late 1800s, pinyon–juniper woodland across western U.S. has increased in density and areal extent encroached into former grassland areas. The San Carlos Apache Tribe wants to gain qualitative quantitative information on historical conditions of their tribal woodlands use as a baseline for restoration efforts. At Reservation, east-central Arizona, large swaths containing varying mixtur...

The composition of the essential oil from ripe and unripe berries and leaves of Juniperus oxycedrus L. ssp. oxycedrus, Juniperus phoenicea ssp. turbinata and Juniperus communis ssp. communis was analyzed by GC-MS, and microbiological assays were carried out. Samples were collected in different localities (Sardinia, Italy) and hydro distilled. The yields ranged between 2.54% +/- 0.21 (v\w dried ...
