Background: Given the importance of Stachys genus in Iran and their significant biological activity, we collected three species of this plant: St. aucheri Benth., Stachys benthamiana Boiss and St. inflata Benth. from different regions of Iran. We examined the free radical scavenging potential, total phenol content and tyrosinase inhibitory activity of their methanol, methanol 80% and dichlorome...
Black liquor alkaline lignin and magnesium lignosulfonate were liquefied at 320 C. The antioxidant abilities of the liquefaction products were compared with the raw materials. Results showed that the total phenol content and unit antioxidant power of both alkaline lignin liquefaction products (ALLP) and magnesium lignosulfonate liquefaction products (MLLP) were improved, and ALLP had a larger i...
Posidonia oceanica meadows are experiencing a progressive decline, and monitoring their status is crucial for the maintenance of these ecosystems. We performed a comparative analysis of bed density, total phenol content and protein expression pattern to assess the conservation status of Posidonia plants from the S. Marinella (Rome, Italy) meadow. The total phenol content was inversely related t...
Phenolic compounds, which are known to regulate root formation, are found abundantly in difficult-toroot Protea cynaroides stem cuttings. In this study, analysis of total phenol content was carried out on blanched and unblanched cuttings to observe its fluctuation throughout the entire rooting period (120 days) and establish its relationship with root formation. Results showed that blanching si...
Mosses contain active constituents that exhibit various biological activities. This study provides additional information on the potentials of mosses as natural sources of biologically active compounds that can be used as medicines. The antioxidant potential of Bryum billardieri Schwaegr. (Bryaceae) is herein studied by analyzing its total phenol content and its radical scavenging activity. Eth...
Euphorbia resinifiera is a well-known medicinal plant used by the Moroccans to treat several diseases. This study evaluated influence of extraction solvents polarities (methanol, aqueous/methanol (3:7), and distilled water) on polyphenols flavonoids contents extracts obtained three methods: infusion, maceration sonication, as well their antioxidant activity. The results revealed that water extr...
