The Pb, Zn and Cd phytoextraction potential of 14 different plants was assessed in a chelate induced phytoextraction experiment. In the used soil heavy metals mainly reside in carbonate, organic matter, and residual soil fractions. The addition of a chelate, 5 mmol/kg ethylenediamine-tetracetic acid (EDTA), increased the proportion of phytoavailable Pb, Zn and Cd in the soil (dissolved in soil ...

Methicillin-resistant Staphylococcus aureus (MRSA) is a global health concern. Many antibiotics are no longer effective at treating MRSA, which causes an increase in adverse patient outcomes. This has led to calls for new and treatment strategies combat the spread of MRSA multidrug resistance (MDR). The antimicrobial secondary metabolites found plants promising source strategies. Cannabis sativ...

The question of energy independence is crucial for many countries in the developed world these days. In addition to solar and wind energy, agriculture plant production are sources renewable energy. Crops can be grown biomass direct combustion, biofuels, bio-ethanol. benefits, lignocellulosic plants have a huge potential wide application industry, construction, paper, automotive, pharmaceutical ...

Electromotive force measurements of cells without liquid junction, of the type Ag, AgCl, HCl + protein, H(2), lead to the conclusion that 1 gm. of edestin (or, more probably, edestan) combines with a maximum of 13.4 x 10(-4) equivalents of H(+) and 3.9 x 10(-4) equivalents of Cl(-), when the protein is dissolved in 0.1 M HCl.

Phytochemical investigation of a high potency variety of Cannabis sativa L. resulted in the isolation of six new metabolites, (+/-)-6,7-trans-epoxycannabigerolic acid ( 2), (+/-)-6,7- CIS-epoxycannabigerolic acid ( 3), (+/-)-6,7- CIS-epoxycannabigerol ( 4), (+/-)-6,7-trans-epoxycannabigerol ( 5), 5'-methyl-4-pentylbiphenyl-2,2',6-triol ( 7), and 7-methoxycannabispirone ( 8), along with seven kn...

Over the past 50 years, a considerable research in medicinal chemistry has been carried out around the natural constituents of Cannabis sativa L. Following the identification of Delta9-tetrahydrocannabinol (Delta9-THC) in 1964, critical chemical modifications, e.g., variation of the side chain at C3 and the opening of the tricyclic scaffold, have led to the characterization of potent and cannab...

The first total synthesis of cannabimovone from Cannabis sativa and anhydrocannabimovone was achieved by means of a highly stereoselective gold(I)-catalyzed cycloisomerization. The results led to reassignment of the structure of anhydrocannabimovone.
