tannic acid/소나무속

This paper intends to shed light on the interactions between tannin and mineral soil particles. For that purpose, aqueous solution of condensed tannin (CT) (derived from Black pine (Pinus nigra var. maritima)) and commercially available tannic acid (TA) were added to purified quartz (Qtz) sand and

m-Chloroperoxybenzoic acid (CPBA) was tested for its ability to induce the ornithine decarboxylase (ODC) marker of skin tumor promotion. In contrast to benzoyl peroxide, dicumyl peroxide, and 2-butanol peroxide, 5 mg of CPBA applied twice at a 72-h interval induce ODC activity at least as much as 3

m-Chloroperoxybenzoic acid (CPBA),which induces ornithine decarboxylase activity as much as 12-O-tetradecanoylphorbol-13-acetate (TPA), was tested for its ability to induce DNA synthesis, hydroperoxide (HPx) production, and tumor promotion in mouse epidermis in vivo. After an early inhibition, CPBA

The antioxidant potential of ethanol extracts from defatted Bokbunja seed wastes generated during wine processing were estimated by radical scavenging abilities (DPPH(*), H(2)O(2), and O(2)(*-)), retardation of lipid oxidation, and iron ion-chelating characteristics. For comparison, ethanol extracts

Swiss stone pine (Pinus cembra) is a slow-growing, hardy tree native to high-mountain regions of Europe from the Alps to the Carpathians. It also is planted as an ornamental in North America. Shoot blight and branch dieback were observed in the fall of 2008 on a single, 25- to 30-year-old Swiss

Black runoff occasionally flows from cutover areas of Eucalyptus plantations, polluting rivers and ponds, and resulting in fish death in severe cases. However, the occurrence patterns and environmental impacts of this black water remain unclear. Herein, we analyzed the major characteristics of black

Eight heterogeneous tannin samples (HTSs) extracted from various tree/shrub leaves of African and Himalayan origin were tested topically for their ability to inhibit the biomarkers of tumor promotion in mouse skin in vivo. HTS2 (from Dichostachys cinerea) and HTS6 (from Cassia sieberiana)

An acidic pine cone extract, Fr. V. of Pinus parviflora Sieb. et Zucc. significantly stimulated DNA synthesis of isolated splenocytes from both mice and rats, but only marginally affected the DNA synthesis of leukemic cell lines. The maximum stimulation level attained by Fr. V slightly exceeded that

This study determined, by means of X-ray absorption near-edge structure (XANES) spectroscopy, the speciation of mercury (Hg) in black pine (Pinus nigra) barks from Monte Amiata, that were previously shown to contain exceptionally high (up to some mg kg-1) Hg contents because of the proximity to the

OBJECTIVE Currently, elemental chlorine-free (ECF) and totally chlorine-free (TCF) bleaching systems are widely used for pulp production. Low and medium molecular weight lignin break-down products are known to have harmful effects on the environment. According to some recent results, also high

Loblolly pine (Pinus taeda) is the major commercial pine species cultivated in the Gulf Coast Region of the southern United States. Symptoms of Diplodia shoot blight (including yellow and brown needles and resin-soaked, dead, small twigs), pycnidia with conidia typical of Diplodia pinea on blighted
