The extracts of five foliar fungal endophytes isolated from Pinus strobus (eastern white pine) that showed antifungal activity in disc diffusion assays were selected for further study. From these strains, the aliphatic polyketide compound 1 and three related sesquiterpenes 2-4 were isolated and

In this study, the antimicrobial activities of several parts of various trees grown in the Kahramanmaraş region of Turkey were investigated by the disc diffusion method. Chloroform, acetone and methanol extracts of leaves, resins, barks, cones and fruits of Pinus brutia Ten., Juniperus oxycedrus L.,

BACKGROUND Pinus roxburghii Sarg. Is one of 3 species of pine found in Nepal, the oil of which is traditionally used to treat cuts, wounds, boils, and blisters. OBJECTIVE To obtain, analyze, and examine the anti-microbial and cytotoxic activities of the essential oils of P. roxburghii. METHODS Three

This study examined the potential biomedical properties of a bark extract from Pinus massoniana Lamb (PMBE). Its antioxidant activity, superoxide anion radical scavenging and free radical scavenging activities were examined. The antioxidant activity in a linoleic acid emulsion increased with

The chemical composition of the essential oils from the needles of Pinus ponderosa (north american pine), P. resinosa (red pine) and P. strobus (eastern white pine) has been determined by GC/MS (FID). The essential oils from P. resinosa and P. ponderosa in comparison to P. strobus have been

Pine knot extract from Pinus pinaster byproducts was characterized by UHPLC-DAD-MS and NMR. Fourteen polyphenols divided into four classes were identified as follows: lignans (nortrachelogenin, pinoresinol, matairesinol, isolariciresinol, secoisolariciresinol), flavonoids (pinocembrin, pinobanksin,

ABSTRACT We have been working on proteins that are involved in the defense response of western white pine (WWP) (Pinus monitcola) to the blister rust fungus Cronartium ribicola. Our objective was to identify candidate genes that could be used for improving resistance of WWP to this rust pathogen.

Bioassay-guided extraction and fractionation of the aqueous methanolic extract of the cones of Pinus densiflora (Pinaceae) afforded one new labdane-type diterpene aldehyde, 15-nor-14-oxolabda-8(17),12 E-diene-18-oic acid, along with eight known diterpenes. Their structures were elucidated using

Essential oils isolated from needles of Pinus patula by hydrodistillation were analyzed by gas chromatography-flame ionization detection (GC-FID) and gas chromatography mass spectrometry (GC-MS). Thirty-eight compounds were identified, representing 98.3% of the total oil. The oil was rich in

From the bark of Pinus strobus infected with pinewood nematode, Bursaphelenchus xylophilus, a stilbenoid 3-O-methyldihydropinosylvin and a flavanone (2S)-pinocembrin were isolated as active principles of inducibly produced antifungal compounds. The structures of the compounds were determined on the

OBJECTIVE To evaluate the antiurolithiatic activity of Pinus eldarica fruit on induced calcium oxalate nephrolithiasis in rats. METHODS Calcium oxalate nephrolithiasis in rats was induced by administering ethylene glycol 1% for 30 days via drinking water. The prophylactic and therapeutic groups

Pinus halepensis Mill. is a pine native to the Mediterranean region that is generally located from sea level up to an altitude of 200 meters. In July 2012, extensive leaf yellowing and scorching were observed on the foliage of two specimens of P. halepensis in a public park of Alassio municipality,

BACKGROUND Traditionally, Pine has been used to treat oxidative and inflammatory disorders. The study was aimed to investigate biological potential of phytoconstituents of Pinus plant species: Pinus roxburghii, Pinus wallichiana and Pinus gerardiana using in-vitro antioxidant, anti-inflammatory and

The bark of Pinus massoniana is a traditional Chinese medicine for the treatment of various health disorders. Previous studies have demonstrated that P. massoniana bark extract (PMBE) may induce the apoptosis of hepatoma and cervical cancer cells. However, whether PMBE is able to inhibit the
