The aim of this study was to investigate and compare Vaccinium myrtillus L. extracts obtained in ultrasonic condition with different water/methanol and water/ethanol extraction mixture acidified with 0.1% HCl. The extracts were analyzed for monomeric anthocyanins contents, total phenolics content and antioxidant activities. The highest anthocyanins content (3888 mg/L), total phenolics content (...

Dunalianosides A-I (1-9), esters of arbutin and related phenolic glucosides, were isolated from the buds of Vaccinium dunalianum Wight (Ericaceae) together with 20 known compounds, and their structures were established on the basis of 1- and 2D NMR spectroscopic evidence. Dunalianosides F-H were dimers of p-hydroxyphenyl 6-O-trans-caffeoyl-beta-D-glucopyranoside (10). The latter was obtained in...

Four important categories of urologic herbs, their history, and modern scientific investigations regarding them are reviewed. Botanical diuretics are discussed with a focus on Solidago spp (goldenrod) herb, Levisticum officinale (lovage) root, Petroselinum crispus (parsley) fruit, and Urtica dioica (stinging nettle) herb. Urinary antiseptic and anti-adhesion herbs, particularly Arctostaphylos u...

6'-O-Caffeoylarbutin, an arbutin derivative, is a naturally occurring glucoside of hydroquinone from Vaccinium dunalianum. On anti-melanogenic effect assay, 6'-O-caffeoylarbutin expressed a stronger anti-melanin activity in a dose-dependent manner with about a two-fold more than that of arbutin, but with less toxicity about a two-fold lower than that of arbutin. In addition, melanin synthesis c...

The root diameters as well as colonization and diversity of the root-associating fungi of Vaccinium oldhamii Miq. were investigated in order to obtain information on their mycorrhizal properties. The distal regions of roots had typical hair roots with diameters of less than 100 μm. Ericoid mycorrhizal fungi (ErMF) and dark septate endophytes (DSE) were frequently observed in the roots. Ascomyce...

The moose (Alces alces) is a dominant large mammalian herbivore in the world’s boreal zones. Moose exert significant browsing impacts on forest vegetation and are therefore often at centre of wildlife-forestry conflicts. Consequently, understanding drivers their foraging behaviour crucial for mitigating such Management parts its range currently largely ignores fact that influenced by increasing...
