BACKGROUND
Ethnobotanical surveys revealed that Abies bornmulleriana, Abies cilicica, Abies nordmanniana and Cedrus libani have been used to promote wound healing in Turkish folk medicine. Four different fir species (Abies cilicica subsp. cilicica, Abies nordmanniana subsp. bornmulleriana, Abies
In the carrageenin-induced paw oedema in rats, (+)-pinitol (2.5-10 mg/kg, i.p.), isolated from Abies pindrow leaves, showed a significant anti-inflammatory effect, the highest dose being comparable to phenylbutazone (100 mg/kg, i.p.).
During the determination of LD50 values of extracts of Abies webbiana, it was observed that the methanol extract (MEAW) produces sedation of animals. This led to investigation of the effect of MEAW on sleeping time in mice. When various doses of the methanol extract (100, 150, and 200 mg/kg body
The phytochemical investigation of Abies chensiensis led to the isolation and identification of nine new compounds including eight triterpenoids (1-8) and a new abietane-type diterpene (9), along with three known compounds (10-12). The absolute configuration of 9 was assigned by X-ray diffraction
Six new triterpenes (neoabieslactones A-F, 1-6) and 17 known compounds were isolated from the aerial parts of Abies chensiensis. The structures of the new triterpenes were proposed by 1D and 2D NMR spectroscopy. Compound 1 was confirmed structurally by X-ray crystallography. In a bioassay against
Chloroform (AGC), ethyl acetate (AGE) and n-butanol (AGB) extracts of Abies georgei were investigated for anti-tumour and anti-inflammatory activities in-vitro and in-vivo. AGC exhibited potent antiproliferative effects against A549, LOVO, QGY-7703 and 6T-CEM tumour cells, with EC50 values of 77.5,
Eleven new abietane-type diterpenes, holophyllins D-N (1-11), and 17 known analogues (12-28), were isolated from a MeOH extract of the trunk of Abies holophylla. The chemical structures of 1-11 were determined through spectroscopic data analysis, including NMR ((1)H and (13)C NMR, DEPT, (1)H-(1)H
A novel spiro-lanostane (abiesatrine A, 1) was isolated from the aerial parts of Abies georgei together with 9 new (abiesatrines B-J, 2-10) and 10 known triterpenes (11-20). The new structures were established by the extensive analysis of their spectroscopic data. The configuration of 1, featuring a
Insecticide synergists biochemically inhibit insect metabolic enzyme activity and are used both to increase the effectiveness of insecticides and as a diagnostic tool for resistance mechanisms. Considerable attention has been focused on identifying new synergists from phytochemicals with recognized
The essential oil from the heartwood of Taiwan fir (EOTC) was demonstrated to exhibit anti-inflammatory activity in lipopolysaccharide (LPS)-activated mouse macrophages. EOTC reduced nitrite oxide levels and inducible nitrite oxide synthase expression in, and tumor necrosis factor-α and
Petroleum ether (PE), benzene (BE), chloroform (CE), acetone (AE) and ethanolic (EE) extracts (50-200 or 200 mg/kg, i.p. or 200 mg/kg, p.o.) of dried Abies pindrow leaves, given 30-45 min before showed significant anti-inflammatory (both against acute and sub-acute models), analgesic, barbiturate
The potential anti-inflammatory efficacy of resin extract of Abies cilicica in glucose dependent inflammation and tumor necrosis factor alpha (TNF-a) induced inflammation models was investigated. Its effects on monocyte adhesion, gene expression levels of P-selectin, ICAM-1, VCAM1 and Three new diterpenoids (1-3) and three new triterpenoids (4-6) were isolated from the trunk of Abies holophylla together with 19 known terpenoids. The chemical structures of 1-6 were determined through NMR and MS data analyses. Also, the structural assignments of some of these compounds were
The fungus Daldinia childiae strain JS-1345, isolated from stem tissue of Abies koreana (Korean fir), has shown strong anti-inflammatory activity. Here, we report the genome sequence of D. childiae JS-1345. The final assembly consisted of 133 scaffolds totaling 38,652,569 bp
Silver fir (Abies alba) bark extract contains a mixture of bioactive polyphenols. We tested their effectiveness in the treatment of psoriasis in order to further investigate the potential topical anti-inflammatory activity of polyphenols by means of a randomized, double-blind, placebo-controlled
