“…The content of salicin derivatives ranged from 2.5 to 10% for S. purpurea. The highest content of salicin in S. viminalis was analyzed in the extract of 2-year-old willow (0.42%) (Kenstavičienė et al 2009). In the analysis of salicin by HPLC-DAD, the content of salicin in the bark of S. purpurea was 17.6% (Schmid et al 2001), which was higher than in S. purpurea examined by Kenstavičienė et al (2009).…”

“…The separation of the mixture of salicylic compounds, such as salicin, picein, salidroside, populin and tremulacin, was conducted with the use of HPLC method in different studies by Pobłocka-Olech (2006), Kenstavičienė et al (2009), Schmid et al (2001 and others. The amount of salicin in S. purpurea bark extract ranged from 1 mg/g to 25 mg/g, depending on the clone, while in the bark extract of S. viminalis it was not detected (Pobłocka-Olech 2006).…”

To determine the percentage of salicin in different species of Salix depending on the age of the species and its harvesting period, HPLC-UV method was used by Kenstavičienė et al (2009).

Key message Liquid chromatography is the main method for assaying bioactive compounds in biomass. Total phenolic content and antioxidant capacity are measured with spectroscopy. Phenolics are the most important bioactive substances in short rotation coppice. Secondary metabolites of black locust, willow and poplar have many different activities. The richest source of bioactive compounds are flowers, bark and buds. Abstract The black locust (Robinia pseudoacacia), willow (Salix spp.) and poplar (Populus spp.) may be the source of the biomass obtained from natural habitats as well as intentionally established plantations in the system of short rotation coppice. These species are promising candidates as an alternative source of bioactive compounds in researches for developing new bioproducts for multidirectional uses, including polymers, lubricants, construction materials, pharmaceuticals, as well as bioenergy and fuels. Various parts of plants, such as leaves, flowers, seeds, bark, woods, buds, catkins, whole tree material and bee products (honey, propolis) are a source of bioactive compounds. The characterization of these compounds, especially phenolic compounds (flavonoids, stilbenes, lignans, phenolic acids, tannins and phenolic glucosides), fatty acids, sterols, etc. may be determined by a variety of analytical (spectroscopy, chromatography) and extraction methods. This review contains 131 references and systematize all available data on the characterization of the bioactive compounds in the biomass of black locust, poplar and willow by analytical and extraction methods.

“…This could be attributed to the fact that most of the b-glucosides are transient in soil and are readily converted to other forms by biotic or abiotic factors [26]. Compared with other secondary metabolites, b-glucosides are quite abundant in plants, especially in Salicaceae members [9,27,28], and are more likely to be encountered in the soil (derived from decomposing vegetation) than in the animal gut. This is consistent with the niche-specific difference in the pattern of b-glucoside utilization by different members of Enterobacteriaceae mentioned before.…”

Hydrolysis of aromatic β-glucosides by non-pathogenic bacteria confers a chemical weapon against predators

et al. 2013

Bacteria present in natural environments such as soil have evolved multiple strategies to escape predation. We report that natural isolates of Enterobacteriaceae that actively hydrolyze plant-derived aromatic b-glucosides such as salicin, arbutin and esculin, are able to avoid predation by the bacteriovorous amoeba Dictyostelium discoideum and nematodes of multiple genera belonging to the family Rhabditidae. This advantage can be observed under laboratory culture conditions as well as in the soil environment. The aglycone moiety released by the hydrolysis of b-glucosides is toxic to predators and acts via the dopaminergic receptor Dop-1 in the case of Caenorhabditis elegans. While soil isolates of nematodes belonging to the family Rhabditidae are repelled by the aglycone, laboratory strains and natural isolates of Caenorhabditis sp. are attracted to the compound, mediated by receptors that are independent of Dop-1, leading to their death. The b-glucosides-positive (Bgl þ ) bacteria that are otherwise non-pathogenic can obtain additional nutrients from the dead predators, thereby switching their role from prey to predator. This study also offers an evolutionary explanation for the retention by bacteria of 'cryptic' or 'silent' genetic systems such as the bgl operon.

“…Ainda não estão estabelecidos os níveis bioquímicos de AS para diferentes matrizes vegetais. A quantidade de AS em plantas é influenciada pelas estações, variável de acordo com sua idade e não há correlação quantitativa entre as espécies [64]. O procedimento analítico é inédito e adequado à determinação de AS em materiais vegetais com vantagens de ser rápido, suficientemente sensível, seletivo e robusto para a determinação de AS em folhas de soja.…”
