salicortin/ヤナギ

Phenolic constituents of Salix reticulata (Salicaceae) and antiproliferative activity of an extract and individual compounds were investigated in immortalized human non-tumorigenic keratinocytes (HaCaT). A MeOH extract from aerial parts afforded several flavonoids, including luteolin and apigenin

Salix alba (SA), commonly known as white willow, is a plant used in folk medicine for the treatment of chronic and acute inflammation, infection, pain, and fever. The phytochemical characterization of the bark extract of this plant indicated that its main component is salicin, a precursor of

The effect of CO2 enrichment (700 and 1050 ppm) on phytomass, soluble sugars, leaf nitrogen and secondary chemicals of three Salix myrsinifolia clones was studied in plants cultivated at very poor (sand seedlings) and moderate (peat seedlings) nutrient availability and under low illumination. The

Nine S. MYRSINIFOLIA clones were studied for secondary phenolics and phytomass production in an old, unfertilized hayfield after the second growing season. S. MYRSINIFOLIA is one of the most promising willow species for the production of herbal drug material. Its salicylate content is moderately

Willow bark is one of the few plant raw materials which contain natural active substances that have analgesic, fever-reducing, anti-inflammatory and anti-rheumatic effects. Salix purpurea, listed as widespread and common in many countries, belongs to the willow species with the highest content of

We studied the relationship between biosynthesis of salicylates, the main chemical defenses in willow and growth of Salix pentandra by cultivating plants in the presence of 2-aminoindan-2-phosphonic acid (AIP), a powerful inhibitor of phenylalanine ammonia-lyase (PAL: EC 4.3.1.5.). AIP inhibited

Bacterial resistance represents one of the emerging obstacles in plants, animals, and humans that impairs treatment with antibacterial agents. Targeting of the bacterial quorum sensing system is one of the strategies to overcome this problem. Recently, research has been focused on natural and food

We studied the effects of natural wounding by insects and artificial wounding by clipping with scissors on the phenolic chemistry of two willows, Salix myrsinifolia and Salix pentandra. Half of the blade of a mature leaf was removed from each experimental plant either by allowing insects

Preparations containing willow bark extract are popular herbal remedies, but they are mostly standardised with respect to only one compound (usually salicin). RP-HPLC using a C18-column eluted with water:methanol:tetrahydrofuran and coupled to electrospray triple-quadrupole MS and MS/MS was used for
