“…Some of these investigation reported that this species reveal a strong antimicrobial activity against Staphylococcus aureus, Escherichia coli and Klebsiella [8][9][10]. Moreover, a research work reported by Mohamadi et al [11] revealed the identification of seventeen compounds from S. satureioides: piceol, vanillin, ferulic aldehyde, 3,3 0 -bis (3,4-dihydro-4-hydroxy-6,8-dimethoxy-2H-1-benzopyran), 3,3-bis (3,4-dihydro-4-hydroxy-6-methoxy-2H-1-benzopyran), dimethylcaffeic acid, balanophonin, 7-methyl-sudachitin, caffeicacid, p-coumaric acid, isoscutellarein In this work, we describe the testing of ethyl acetate extract parts S. satureioides as corrosion inhibitor for carbon steel (X52) in HCl solution, using weight loss and electrochemical techniques, such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS).…”

The inhibitory effect of the crude ethyl acetate extract of Saccocalyx satureioides was estimated on the corrosion of carbon steel (X52) in 1 M HCl solution sing weight loss measurement, potentiodynamic polarization, electrochemical impedance spectroscopy and scanning electron microscopy techniques. Potentiodynamic polarization curves indicated that the plants extract behaves as a mixed-type inhibitor. The adsorption of the inhibitor on the carbon steel surface was found to follow Freundlich adsorption isotherm. The free energies, enthalpies and entropies for the adsorption and dissolution process were discussed in details. The inhibiting action increases with increasing concentration of the extract. The results obtained show that the extract of the aerial parts of Saccocalyx satureioides could serve as an effective corrosion inhibitor of carbon steel (X52) in hydrochloric acid medium.

“…Ten µL of each diluted extract were then deposited in a microplate well followed by 150 µL of fluorescein 8.5×10 -8 mol/L in Milli-Q water. After a 10-minute incubation at 37 °C, AAPH at 153×10 -3 mol/L in PBS [26][27][28] was automatic distributed in the microplate wells. The fluorescence kinetics was then monitored every 5 min for 120 min using a Vario Skan spectrophotometer with excitation and emission wavelengths of 485 nm and 530 nm, respectively.…”

The extraction of bioactive compounds from medicinal plants requires methods which are as diverse as the chemical nature of the compounds themselves. In this study, a 96-well microplate was used where solvent mixtures spanning wide ranges of selectivity and polarity were tested with the objective of extracting a broad range bioactive compounds from plant material. Microplate wells were filled with plant material and the solvents and their mixtures were added. The obtained extracts were assessed in terms of their total antioxidant activity, oxygen radical absorbance capacity and effects on cell viability. An aqueous extract, generally used by traditional therapists, was also included in the study. The results showed that the extracts using methanol with acetic acid (0.1%, v:v), chloroform/ethanol, butanol/DMF, butanol/acetonitrile, ethylene glycol with acetic acid (0.1%, v:v), MTBE/DMSO, ethylene glycol, pentane/ethanol (v:v), ethanol, DMF, DMF with acetic acid (0.1%, v:v), DMSO, DMSO with acetic acid (0.1%, v:v) and THF had a higher antioxidant activity than the aqueous extract. Extracts with greater antioxidant activity than the aqueous extract were obtained largely from solvent mixtures with the exception of ethanol, DMF, DMSO and THF. The antioxidant activity obtained in TEAC varied between 1474.1±4.4 and 3183.0±16.0 μmol TE/g dry extract respectively for aqueous and THF extracts; in ORAC between 1727.7±8.4 and 2683.5±11.7 μmol TE/g dry extract for aqueous and DMSO acetic acid 1%, respectively, with mean ±SEM. In TEAC the THF extract had the highest antioxidant potential with 3183.0±16.0 μmol TE / g dry extract. The DMSO acetic acid (0.1%, v:v) extract had the highest antioxidant potential in ORAC with 2683.5±11.7 μmol TE / g dry extract. Cell viability test using β-pancreatic cells showed that only the acidified methanol extract was toxic after one hour of incubation. After 24 hours, cell viability was less than 70% for extracts using butanol/acetonitrile, MTBE/DMF, acidified methanol, pentane/ethanol and acidified DMF.

“…Our research group has been interested in the transformation of vegetable oils to UV absorbing and anti‐oxidant cosmeceutical ingredients . The associated anti‐oxidant and UV absorbing properties of ferulic acid makes this chemical moiety a desirable addition to vegetable oils . Indeed, several feruloylated intermediates that synthetically lead to anti‐oxidant derivatives of vegetable oil based bioproducts are found in nature, including 1‐feruloyl‐ sn ‐glycerol, 1,2‐diferulyol‐ sn ‐glycerol and 1,3‐diferuloyl‐ sn ‐glycerol .…”
