a new kaempferol glycoside with antioxidant activity from,abstract: the current study aimed to identify the chemical constituents of chenopodium ambrosioides (linn.), and the assessment of the in vitro antioxidant activity of the different extracts and pure isolates. methods: the antioxidant activity was estimated via free radical scavenging and phosphomolybdenum assays.
desert plants possess untapped potential for medicinal applications due to their rich phytochemical profiles. however, they need to be more explored. thus, this study integrates advanced analytical, biochemical, and molecular techniques to investigate the phytochemical composition and biological activities (antimicrobial and antioxidant) of four desert plants (pergularia tomentosa, zygophyllum

phytochemical screening and antioxidant activity of some,antioxidant activity. dpph abts frap. phenolic acid flavonoids phytochemicals. abstract. rmis were screened for phytochemicals in ethanol (80%), hexane, and ethyl acetate. the potential of plant extracts to scavenge free radicals.
unveiling the chemical composition, bioactive profile
higher levels of chlorogenic acid enhance the effectiveness of scavenging the dpph radical, as indicated by the latest results. moreover, flavonoids are a widespread category of phenolic chemicals that exhibit antioxidant activity in laboratory settings, primarily due to derivatives of naringenin . naringenin is a prominent flavonoid compound
chemical profile, antioxidant and anti-alzheimer activity of,the antioxidant activity, anti-acetylcholinesterase (anti-ache), anti-butyryl cholinesterase (anti-bche) and aβ-amyloid-42 inhibition activities of the ethanolic extracts of both leaves and flowers (lee and fee) of markhamia lutea were assessed.
- Which plant extract has the highest DPPH scavenging and antitumor activity?
- The highest contents of polyphenols, flavonoids and antioxidant capacity were recorded in V. candicans extract. However, the highest DPPH scavenging and antitumor activities were reported in the extract of S. vermiculata. The antioxidant and antitumor activities of the extracts are mainly dependent on their active constituents.
- What is the Order of decreasing antioxidant activity in ethanolic extracts?
- The order of decreasing antioxidant activity in the ethanolic extracts of plants was V. candicans > S. vermiculata > C. dioscoridis > P. harmala with values of 368.2, 216.9, 165.0, and 92.9 μg ascorbic acid equivalent/g d.wt, respectively.
- Which plant extract has the lowest IC50 against DPPH?
- Moreover, the extract of Suaeda vermiculata exhibited the lowest half maximum inhibitory concentration (IC50) against DPPH, thus indicating its highest effectiveness. All studied plant extracts decreased the viability of HepG2 cells, in a dose- and time-dependent manner, and the lowest IC50 was for Suaeda vermiculata.
- Which extract is the best against DPPH?
- The results showed that Varthemia candicans extract was the highest one regarding both polyphenols and flavonoid contents. Moreover, the extract of Suaeda vermiculata exhibited the lowest half maximum inhibitory concentration (IC50) against DPPH, thus indicating its highest effectiveness.
