Robinia pseudoacacia L. - Fabaceae - black locust, false acacia, Robinie, Falsche Akazie, Scheinakazie

Invasive tree, native to eastern North America, naturalized throughout the world; 15-25m high; inflorescence a pendent cluster; flowers white, scenting sweet like bergamot orange.

„Important constituents of the plant are the toxalbumin robin, which loses its toxicity when heated and robinin, a non-toxic glucoside.“

„The floral fragrance headspace of living Robinia pseudoacacia was trapped on Tenax tube cartridges using air as the carrier. After solvent elution, the major components identified using GC/MS were δ-3-carene (54.6%), linalool (21%), (Z)-β-farnesene (3.0%) and anthranilate aldehyde (3.9%).“

„Volatiles from the fresh flowers of Robinia Pseudoacacia L. grown in China were analyzed by GC-MS combined with solid-phase microextraction (SPME). The abundant compounds identified were linalool (33.1%), cis-β-ocimene (26.6%), (E)-α-bergamotene (8.9%) and formanilide (7.4%).“

„The identification of phenolic compounds by UPLC–DAD–MS/MS revealed, for the first time, the presence of resveratrol and piceatannol. These two stilbenes as well as the flavonoid dihydrorobinetin were present at the highest level in mature heartwood, and as they are known antifungals, they could account for the great durability of mature heartwood. The stilbenes were detected in significant amounts particularly in mature heartwood where piceatannol reached a level tenfold higher than that reported for Japanese knotweed roots, the primary natural source of these stilbenes, whereas resveratrol level was comparable with reported values.“
