“…European larch (Larix decidua L.) is a deciduous tree that grows to 35 m and is indigenous to the Alps, the Sudetes, and the Carpathian mountains (von Bruchhausen et al 1993;Pferschy-Wenzig et al 2008). Larch wood is strong, water-resistant, and durable, but especially bendable in thin strips.…”

“…The heartwood is extremely weather-proof due to its excessive resin content and hard machinability, and it is usually used as building timber (Pferschy-Wenzig et al 2008). Larch sawdust is principally utilized in the production of pellet fuels, and the wood contains phenolic compounds such as lignans and flavonols (mainly dihydroquercetin and dihydrokaempferol) (von Bruchhausen et al 1993). These compounds possess antioxidant and anti-inflammatory effects (Kolhir et al 1996;Pietarinen et al 2006).…”

“…Previous studies have been dedicated to analyzing the chemical composition of the essential oils and the antimicrobial activities of several parts of Pinaceae members (needles, branches, cones, seeds, and bark) (Grassmann et al 2003;Nikolić et al 2007;Tumen et al 2010;Bier et al 2016;Fattahi et al 2016;Salem et al 2016). Nevertheless, the majority of studies regarding the chemical composition of softwood species have related to North American and Central European species (Hennig et al 1994;Danneyrolles et al 2016;Greenberg et al 2016;Krieg et al 2016).European larch (Larix decidua L.) is a deciduous tree that grows to 35 m and is indigenous to the Alps, the Sudetes, and the Carpathian mountains (von Bruchhausen et al 1993;Pferschy-Wenzig et al 2008).

Picea abies and Larix decidua were subjected to GC/MS analyses, and antimicrobial (fungi and bacteria) assays of their stem wood and bark extracts were investigated. L. decidua bark extract exhibited the highest antifungal and antibacterial activities against the microorganisms that were screened. The microbes Penecillium ochrochloron and Aspergillus ochraceus were the most sensitive to the extracts, whereas Candida albicans was the most resistant fungus. L. decidua wood and bark did not exhibit much variation in their antibacterial activities, except against Micrococcus flavus and Pseudomonas aeruginosa. The bacterium most sensitive to the extracts was Escherichia coli, whereas the most resistant was M. flavus. 13-epimanool and α-cedrol were the main components of P. abies wood extract. The main components in its bark were abietic acid, astringin, dehydroabietic acid, and α-terpineol. The main chemical compounds in L. decidua wood extract were abietic acid, oleanolic acid, duvatrienediol, and larixol. The main chemical compounds in its bark were (-)-2,9-dihydroxyverrucosane and larixol. The study revealed that P. abies and L. decidua stem wood and bark extracts contain several compounds that have antimicrobial activities towards diverse human pathogenic, food, and agricultural microbes. These results might guide in future searches for novel natural products with chemotherapeutic uses.

Tree bark, for example, provides not only a physical protective barrier for plants, but also an important chemical defense mediated through the secondary compounds they produce (Horsfall 1980;Merrill 1992;Alfredsen et al. 2008). Numerous studies recently conducted on bark extracts focus on tropical tree spec...
