In this study, the authors aimed to compare the phytochemical compounds (polyphenols and flavonoids), antioxidant activity, functional groups present in the compounds (FTIR), and anti-microbial effects, in the aqueous and methanol extracts obtained from flowers of commercial Hypericum perforatum and native Papaver Rhoeas from Morocco. P. Rhoeas L was collected from El Lhaj Kaddour near Meknes, while H. perforatum L was bought in a dried state from a Moroccan herbalist in the same city. Total polyphenols were evaluated using the Folin-Ciocalteu reagent, respectively. The antioxidant activity was assessed via DPPH and antimicrobial effects were tested against six bacteria (Gram– and Gram+). The aqueous and methanol extracts of P. Rhoeas had the highest TPC value (23.67 ± 0.94 mg GAE/g; 15.86 ± 0.65 mg GAE/g) compared to H. perforatum (15.26 ± 1.30 mg GAE/g; 5.50 ± 1.13 GAE/g). The aqueous extract of Papaver Rhoeas exhibited the highest TFC at 14.36 ± 0.49 mg QE/g, while the methanol extract of Hypericum perforatum had the highest 10.65 ± 0.49 mg QE/g in TFC. In contrast, the methanol and aqueous extracts of H. perforatum showed significant zones of inhibition against Staphylococcus aureus (9.5 ± 0.5 mm and 10.17 ± 0.29 mm) and Staphylococcus epidermidis (8.33 ± 0.58 mm and 9.33 ± 0.58 mm) respectively, with a minimum inhibitory concentration was estimated at 10 μL/ml. The FTIR analysis demonstrated that the extracts of both plants are rich in bioactive molecules with potential biological activities and a pharmaceutical industry perspective. Consequently, these Papaver Rhoeas and Hypericum perforatum extracts exhibit antioxidant and antibacterial activities.

The powders of Ammi visnaga L. and Calendula officinalis L. plants collected from Meknes region were subjected to three types of analysis, including Fourier transforms infrared spectroscopy (FTIR) analysis, CHNS/O analysis, and ICP-AES analysis with the aim of comparing and giving an insight into the nutritional value, medicinal properties, and potential applications in different fields. The results of the FTIR analysis showed absorbance bands in the same wavelengths, but with different peaks, indicating the presence of long-chain linear aliphatic compounds, lipids, amides, aromatic compounds, and other functional groups in both plants. The CHNS/O analysis revealed high levels of carbon and oxygen, followed by hydrogen, nitrogen, and sulfur for both plants, with no significant differences in the values. The ICP analysis detected 16 minerals, including calcium, potassium, phosphorus, and magnesium in Ammi visnaga, and low levels of sodium in comparison to Calendula officinalis. Calendula officinalis accumulated more aluminum and lead than Ammi visnaga, indicating higher tolerance to contaminations. Zinc, iron, manganese, and copper were important micronutrients present in both plants. The findings of this study suggest that both plants have significant amounts of phytochemical compounds and minerals, which could be beneficial for their potential use in the pharmaceutical, nutraceutical, and cosmetic industries.
