ETHNOPHARMACOLOGICAL RELEVANCE: The fruits of Juniperus rigida have been used in Korean traditional medicine for the treatment of inflammatory diseases in humans such as rheumatoid arthritis. AIM OF THE STUDY: This study aimed to investigate the anti-atopic properties of J. rigida fruit in in vivo murine atopic dermatitis (AD) models. METHODS AND RESULTS: BALB/c mouse ears ad SKH-1 hairless mice stimulated with oxazolone (4 weeks) and DNCB (3 weeks), respectively, were treated with the 1% Juniperus rigida fruit EtOH extract (JFE)...

The allelopathic effects of Juniperus rigida litter aqueous extract (LE) on wheat and Pinus tabuliformis were studied, as well as the physiological responses to the extract. High concentration LE (0.10 g Dw/ml) significantly inhibited the seed germination and seedling growth in receptor plants. The chlorophyll content and root activity in the wheat seedlings were reduced significantly across all treatments; however, those were more prominently reduced at high concentration (0.10 g Dw/ml) but received little stimulation at low concentration (0...

Juniperus rigida (J. rigida) which is endemic to East Asia, has traditionally been used as an ethnomedicinal plant in China. This study was undertaken to evaluate the quality of J. rigida samples derived from 11 primary regions in China. Ten phenolic compounds were simultaneously quantified using reversed-phase high-performance liquid chromatography (RP-HPLC), and chlorogenic acid, catechin, podophyllotoxin, and amentoflavone were found to be the main compounds in J. rigida needles, with the highest contents detected for catechin and podophyllotoxin...

The chemical composition and antioxidant activity of essential oils and MeOH extracts of stems, needles, and berries from Juniperus rigida were studied. The results indicated that the yield of essential oil from stems (2.5%) was higher than from needles (0.8%) and berries (1.0%). The gas chromatography/mass spectrometer (GC/MS) analysis indicated that 21, 17, and 14 compounds were identified from stems, needles, and berries essential oils, respectively. Caryophyllene, α-caryophyllene, and caryophyllene oxide were primary compounds in both stems and needles essential oils...

The trace proteome of a Braulio aperitif (a 21% alcohol beverage, named after a mountain in the Val di Stelvio, Italy) has been investigated via capture with combinatorial peptide ligand libraries (CPLL, ProteoMiner). This aperitif is made with an infusion of 13 mountain herbs and berries, among which four are officially indicated in the label: Achillea moschata, juniper (Juniperus communis subsp. alpina) berries, absinthe (Artemisia absinthium) and gentian (Gentiana alpina) roots. Via capture with CPLLs at pH 7...

A new lignan glycoside, named juniperigiside (1) was isolated from the CHCl(3) soluble fraction of the MeOH extract of stems and leaves of Juniperus rigida S.et Z. Compound 1 was identified by 1D- and 2D-NMR spectroscopy as well as CD analysis as (2R,3S)-2,3-dihydro-7-methoxy-2-(4'-hydroxy-3'-methoxyphenyl)-3-hydroxymethyl-5-benzofuranpropanol 4'-O-(3-O-methyl)-α-L-rhamnopyranoside. Five known lignans, icariside E4 (2), desoxypodophyllotoxin (3), savinin (4), thujastandin (5), and (-)-nortrachelogenin (6) in addition to five known labdane diterpenes including trans-communic acid (7), 13-epi-torulosal (8), 13-epi-cupressic acid (9), imbricatoric acid (10), and isocupressic acid (11) were also isolated and their structures were characterized by comparing their spectroscopic data with those in the literature...

Inflammation is an essential host defense system particularly in response to infection and injury; however, excessive or undesirable inflammatory responses contribute to acute and chronic human diseases. A high-throughput screening effort searching for anti-inflammatory compounds from medicinal plants deduced that the methanolic extract of Juniperus rigida S. et L. (Cupressaceae) inhibited significantly nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. Activity-guided fractionation and isolation yielded 13 phenolic compounds, including one new phenylpropanoid glycosides, 3,4-dimethoxycinnamyl 9-O-β-D-glucopyranoside (1)...

The distribution and hosts of the exotic cedar-boring beetle, Callidiellum rufipenne (Motschulsky) (Coleoptera: Cerambycidae), were determined in five northeastern U.S. states by capturing adults on cedar trap logs and by rearing adults from various conifers. This beetle was detected in the coastal states of Massachusetts, Rhode Island, Connecticut, New York, and New Jersey. In these states, adults emerged from the live or dead wood of four genera and eight species of Cupressaceae; species of Pinaceae were not hosts...

Dust removal by plants was proposed as an important basis of designing urban green space system for future urbanization. Dust removal measurement and leaf surface electron-microscopic scanning were taken for 28 tree species in Harbin city. The results showed that there were obviously different effects of dust removal among different tree species. Picea koraiensis and Juniperus rigida were the ideal conifers for dust removal, and their dust removal abilities were 5.7 g.m-2 and 4.4 g.m-2 after 4 weeks, respectively...

We investigated effects of stem phloem girdles on apical control of branch angle, stem and branch growth and stem air content in six conifer species. A stem girdle 2 cm above a branch caused the branch to bend upward in all six species. Upward bending was associated with increased formation and action of compression wood (CW) in the lower portion of the branch. Compression wood also formed in the main stem below the branch, suggesting increased auxin production in the branch. A stem girdle 2 cm below a branch (the branch remained directly connected to the apex and distal branches) released the branch from apical control in Tsuga canadensis (L...

The composition of the leaf essential oils of all the species of Juniperus in sect. Juniperus (=sect. Oxycedrus) are reported and compared (J. brevifolia, J. cedrus, J. communis, J. c. var. saxatilis, J. c. var. oblonga, J. formosana, J. oxycedrus, J. o. subsp. badia, J. o. subsp. macrocarpa, J. o. subsp. transtagana, J. rigida, J. r. subsp. conferta, J. sibirica, J. taxifolia and J. t. var. lutchuensis). In addition, DNA fingerprinting by RAPDs was utilized. Based on these data, several taxa remained at the same taxonomic level: J...

We investigated the allergenicity of pollen extract of Japanese juniper (Juniperus rigida, Cupressaceae family) to sera of 49 asthmatic children by the methods of enzyme-linked immunosorbent assay (ELISA) and immunoblotting. Three bands stained with Coomassie Brilliant Blue R were detected on SDS-PAGE. Sera from 27 (55.1%) out of the 49 children showed positive reaction to the pollen extract in ELISA. The same sera from the 27 children were used as the first antibody in immunoblotting, which confirmed the presence of a band of protein with 70 K dalton molecular weight (M...

Atmospheric cedar pollen in the southern region of Okayama Prefecture (situated in south-western Japan) has been counted since 1988. Pollen of different species of the Taxodiaceae family (Cryptomeria japonica, Sequoia sempervirens and Metasequoia glyptostroboides) and Japanese juniper (Juniperus rigida) in the Cupressaceae family, which are propagated mainly in the southern region of Okayama Prefecture, were found among the atmospheric pollen. Scratch tests using the pollen extract from Taxodiaceae and Cupressaceae were performed on children with bronchial asthma...
