[MPWG] Medicinal black locust?

[emanuela at medicaltraditions.org]

There are geneticists in Turkey who have been working for some time on
_Robinia pseudoacacia_ (Black locust) to test its antibacterial
properties:

Characterization of bioactive compounds in the biomass of black locust,

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 ...

Then, there is a team of scientists from Egypt and Iran who have been
working on the antibacterial and antifungal properties of this tree:

Finally, I include the work done by a team of scientists in Romania, who
investigated the antimicrobial and antioxidant activity of ethanol
extracts obtained from the leaves, seeds and sheaths of Black locust:

This study was aimed at investigating the antimicrobial and antioxi-
dant activity of ethanol extracts obtained from the leaves, seeds and
sheaths of Robinia pseudoacacia. Total phenolic content (TPC,
Folin-Ciocalteu method), antioxidant activity (trolox equivalent
antioxidant capacity (TEAC) assay) and antimicrobial activity (agar disk
diffusion method and broth dilution method) of the vegetative and
reproductive organs of R. pseudoacacia were determined. The highest
content of polyphenols (expressed as gallic acid equivalents, GAE) was
found in the extract of R. pseudoacacia leaves (266.7 μg GAE mL -1 ext-
ract) followed by the extract of the seeds (232.2 μg GAE mL -1 extract).
HPLC analysis showed the presence of catechin (0.925 μg mL -1 ), rutin
(0.831 μg mL -1 ), resveratrol (0.664 μg mL -1 ) and quercetin (0.456 μg
mL -1 ) in the leaf extract, and catechin (0.127 μg mL -1 ), epicatechin
(0.239 μg mL -1 ) and rutin (0.231 μg mL -1 ) in the seed extract. The
results showed that the studied extrac

Subject: [MPWG] Medicinal black locust? 

Hi All, 

Patricia's message about slippery elm made me think of one of my
favorite trees, black locust. 

The wood of black locust resists decay for many years. It has powerful
antibacterial and antifungal properties. In light of the spread of
antibiotic resistance, I wonder how thoroughly this species is being
researched as a source of antibacterial compounds. 
Does anyone on this list know of any such research into the medicinal
properties of black locust? We should encourage such research. 

Best, 
Mike Schenk
