The temperature and the process used to extract metals from plant as mixture of Lewis acids were investigated in detail and proved to be essential in the design of the biosourced catalysts and their catalytic efficiency. One part of the crude mixture of Lewis acids extracted from the aerial parts of miscanthus plants was used without further treatment as a homogeneous biocatalyst (M1), and the other part was supported on montmorillonite K10 to provide a heterogeneous biocatalyst (MM1). M1 and MM1 were next tested in the synthesis of moclobemide (main ingredient of a drug used to treat depression) and led to excellent yield. Additional comparative experiments with different commercial metallic salts (NaCl, KCl, CaCl2, MgCl2, CuCl2, ZnCl2, FeCl2, FeCl3, MnCl2, and AlCl3) and their mixtures were carried out and underlined the importance of the multimetallic synergy on catalytic activity. Finally, a comparison of this new synthetic method assisted by the biosourced catalyst with the previously described procedures to access moclobemide was realized by calculating their green chemistry metrics. This study revealed that the use of the biosourced catalyst led to one of the greenest synthetic methods described today to produce moclobemide.},

The conception of two biosourced catalysts (biocatalysts) using stems of miscanthus from the first part of this study are described herein. The temperature and the process used to extract metals from plant as mixture of Lewis acids were investigated in detail and proved to be essential in the design of the biosourced catalysts and their catalytic efficiency. One part of the crude mixture of Lewis acids extracted from the aerial parts of miscanthus plants was used without further treatment as a homogeneous biocatalyst (M1), and the other part was supported on montmorillonite K10 to provide a heterogeneous biocatalyst (MM1). M1 and MM1 were next tested in the synthesis of moclobemide (main ingredient of a drug used to treat depression) and led to excellent yield. Additional comparative experiments with different commercial metallic salts (NaCl, KCl, CaCl2, MgCl2, CuCl2, ZnCl2, FeCl2, FeCl3, MnCl2, and AlCl3) and their mixtures were carried out and underlined the importance of the multimetallic synergy on catalytic activity. Finally, a comparison of this new synthetic method assisted by the biosourced catalyst with the previously described procedures to access moclobemide was realized by calculating their green chemistry metrics. This study revealed that the use of the biosourced catalyst led to one of the greenest synthetic methods described today to produce moclobemide. |

abstract = {Although growing vegetables in urban gardens has several benefits,
some questions in relation with the safety of foods remain when the
self-production is carried out on highly contaminated garden soils.
To better assess the local population's exposure to Cd and Pb induced
by the past activities of a lead smelter, a participatory program
was initiated in 115 private kitchen gardens located in northern
France to assist gardeners in understanding their soil environment.
The challenge included contributing to the database of urban garden
soils with the collection of a large number of samples: 1525 crops
grouped into 12 types (leaf, fruiting, root, stem and bulbous vegetables,
tubers, cabbages, leguminous plants, celeriac, fresh herbs, fruits,
and berries), 708 topsoils, and 52 samples of self-produced compost.
The main results were as follows: (i) topsoils were strongly contaminated
by Cd and Pb compared to regional reference values; (ii) great variability
in physicochemical parameters and metal concentrations in topsoils;
(iii) the highest concentrations of Cd and Pb for celeriac and fresh
herbs and the lowest for fruits and fruiting vegetables; (iv) a high
percentage of vegetables that did not comply with the European foodstuff
legislation; and (v) most self-produced compost samples were strongly
contaminated. This study aimed to raise awareness and generate functional
recommendations to reduce human exposure and to provide useful data
that could be considered in other environmental contexts.},
