C. tamala leaves are mainly used for flavouring food and spice due to clove like taste and pepper like odour. The plant leaves are widely used in pharmaceutical preparation because of therapeutic efficacy against various diseases and disorders due to presence of different phytochemicals. The leaves were analysed for ash content, moisture, crude fat, crude fibre, crude carbohydrate, crude protei...

Improvement of eco-friendly procedures for the nanoparticles synthesis is the growing in to the field of nanotechnology. In this report we used the extract of marine brown seaweed Turbinaria conoides for the silver nanoparticles synthesis is the new one, cost effective and environmentally favorable. The surface plasmon resonance band positioned at 420 nm for silver nanoparticles was characteriz...

Dissolved lignin phenols and optical properties of dissolved organic matter (DOM) were measured to investigate the sources and transformations of terrigenous DOM (tDOM) in Otsuchi Bay, Japan. Three rivers discharge into the bay, and relatively high values of syringyl:vanillyl phenols (0.73 ± 0.07) and cinnamyl:vanillyl phenols (0.33 ± 0.10) indicated large contributions of non-woody angiosperm ...

The first three enzymes of the pentachlorophenol (PCP) degradation pathway in Sphingobium chlorophenolicum (formerly Sphingomonas chlorophenolica) ATCC 39723 have been characterized, and the corresponding genes, pcpA, pcpB, and pcpC, have been individually cloned and sequenced. To search for new genes involved in PCP degradation and map the physical locations of the pcp genes, a 24-kb fragment ...

The development of metal base pairs is of immense importance for the construction of DNA nanostructures. Here we report the synthesis of a biaryl pyrazole-phenol nucleoside that forms in DNA a stable self-pair upon complexation of a Cu(II) ion. A sequence with five consecutive pyrazole nucleotides allows the complexation of five Cu(II) ions in a row.

The phosphorous-based flame retardant additives poly(m-phenylene methylphosphonate) (PMP) and resorcinol bis(diphenyl phosphate) (RDP) are reacted with bisphenol F aniline–based benzoxazine (BF-a). DSC, rheological analysis, FT-IR, soxhlet extraction reveal the covalent incorporation of both FR additives—initiating phenols in PMP structure as well free generated via transesterification reaction...

BACKGROUND Maternal urinary biomarkers are often used to assess fetal exposure to phenols and their precursors. Their effectiveness as a measure of exposure in epidemiological studies depends on their variability during pregnancy and their ability to accurately predict fetal exposure. OBJECTIVES We assessed the relationship between urinary and amniotic fluid concentrations of nine environment...

In the title salt {systematic name: [2-hy-droxy-3-(3-meth-oxy-phen-yl)cyclo-hexyl-meth-yl]dimethyl-aza-nium 2,4,6-trinitro-phenol-ate}, C(16)H(26)NO(2) (+)·C(6)H(2)N(3)O(7) (-), the cation is protonated at the N atom. The cyclo-hexane ring adopts a chair conformation with the hy-droxy substituent in an axial position. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the cations and anions in...

The transition-metal-catalyzed amination of aryl halides has been the most powerful method for the formation of aryl amines over the past decades. Phenols are regarded as ideal alternatives to aryl halides as coupling partners in cross-couplings. An efficient palladium-catalyzed formal cross-coupling of phenols with various amines and anilines has now been developed. A variety of substituted ph...
