“…It was reported that larger amounts of B extractives than obtained in our study can be gained by extracting bark of black locust with a mixture of methanol and water (Sablik et al 2016). PT and resveratrol were identified at a significant concentration in mature heartwood of black locus by Sergent et al (2014), but this was not confirmed by our chromatographic analysis. In addition to flavonoids, bark of trees can contain polyphenols of higher molecular mass, i.e., condensed tannins (Holmbom 2011;Smith et al 1989).…”

“…It is assumed that the higher content of HE and TP in WW than in intact SW and HW can be explained by the two-stage process, which involves WW formation and therefore transformation of WW to HW. This observation indicates that DHR may be classified as phytoalexin (Hart and Shrimpton 1979;Pearce 1990;Sergent et al 2014), although furthers studies are needed to confirm this speculation.…”

Variability in content of hydrophilic extractives and individual phenolic compounds in black locust stem

The main goal of this study was to investigate the amounts of hydrophilic extractives in bark and wood samples of black locust stem (Robinia pseudoacacia L.). The concentrations of extractives were highest in the outermost samples of heartwood. Knotwood of black locust contained less DHR than heartwood. Significantly less hydrophilic compounds were extracted from bark and sapwood samples. This study shows that heartwood of black locust can be considered a source of value-adding compounds. The investigation showed significant variability in the content of extractives in a radial direction and less pronounced axial variability within the black locust stems.

“…A good source of flavonoids but also extremely valuable stilbenes (piceatannol and resveratrol) may also be the black locust wood. This raw material can become an economical and sustainable source of bioactive phenolic compounds (Sergent et al 2014). The whole plant collection can be mechanized and profitable (Stolarski et al 2017) and it is certainly less labor and cost-intensive than manual flower or leaf collection.…”

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.

“…Characterized by good growth rates and important biomass production, R. pseudoacacia produces wood of very high natural durability used for outdoor fence posts, but also for timber (e.g., beam, railroad sleepers) [15,16]. Interestingly, the major proportion of its wood corresponds to heartwood (last differentiation step of wood cells) that retains most of its properties due to the accumulation of specific extractives as phenolic substances that increase the natural color and durability of wood [17].…”

“…Two flavonoids dihydrorobinetin (3,3 ,4 ,5 ,7-pentahydroxyflavanone, DHRob) and robinetin (3,3 ,4 ,5 ,7-pentahydroxyflavone, Rob) are the major phenolic compounds that have been extracted from R. pseudoacacia heartwood [18][19][20]. They are present in higher contents in mature heartwood compared to juvenile wood, and have thus been related to the higher decay resistance observed in mature heartwood [16,21,22].…”

Robinia pseudoacacia L. is a tree widely dispersed in France that is characterized by good growth rates and important biomass production, which produces wood with very high natural durability used for outdoor fence posts, timber, and barrels to age vinegars and wines. Its mature heartwood presents high resistance against wood fungi decay and contains two main flavonoid extractives, dihydrorobinetin-the most abundant-and robinetin that present interesting biological activities. The aim of the present study was to optimize a procedure allowing an important recovery of purified dihydrorobinetin from R. pseudoacacia wood, representing an interesting sustainable, local, highly available, and, consequently, economical source of bioactive components. The extraction of dihydrorobinetin was first optimized by evaluating the influence of various extraction parameters such as temperature, extraction time, solvent nature, and wood/solvent mass ratio to obtain an efficient, safe, and low cost extraction. Then, dihydrorobinetin was purified over 95% using centrifugal partition chromatography (CPC). CPC purification was first developed on a small volume column with low amounts of injected extract, then scaled-up on a 200 mL column with higher sample loading capacity in order to purify more than 1.3 g of dihydrorobinetin in one run.
