Phenolic compounds in silver birch (Betula pendula Roth) wood

“…In previous work, we isolated four phenolic glycosides from the wood of silver birch, Betula pendula (Hiltunen et al 2004), which is a white-barked birch tree native to Europe and Asia. Phenolics in the inner bark of B. pendula (Š mite et al 1993, 1995) and several other birch species (Pan and Lundgren 1994;Fuchino et al 1995Fuchino et al , 1996Fuchino et al , 1998a have been studied in more depth.

Medicinal plants of the genus Betula—Traditional uses and a phytochemical–pharmacological review

“…Both betulin and ethanolic extracts (1 pp and 3 pp) were used to determine the reduction of edema. Betulin was found to be comparable with indometacin; however, the extracts revealed the most intense Fuchino et al (1995Fuchino et al ( , 1996aFuchino et al ( , 1996bFuchino et al ( , 1998b 3,4,5-trimethoxyphenol β-D-apiofuranosyl-(1-6)-β-D-glucopyranoside Betula dahurica Fuchino et al (1995Fuchino et al ( , 1996bFuchino et al ( , 1998b Smite et al (1995), Fuchino et al (1996aFuchino et al ( , 1998aFuchino et al ( , 1998bFuchino et al ( , 1998c Betula dahurica Fuchino et al (1995Fuchino et al ( , 1996aFuchino et al ( , 1996bFuchino et al ( , 1998bFuchino et al ( , 1998c, Smite et al (1995), and Mshvildadze et al Betula dahurica Fuchino et al (1995Fuchino et al ( , 1998aFuchino et al ( , 1998b Betula pendula Smite et al (1995) anti-inflammatory potential probably because of the aggregation of effects of other triterpenes, also present in the extract composition, even in small concentrations (betulinic acid, lupeol etc. ).…”
