Biological Activities of Some Isoquinoline Alkaloids from Soy. Will.

Soy. Will. is a species belonging to the Papaveraceae family, being widespread in East-Central and Southern Europe.

Chemical Composition, Diuretic, and Antityrosinase Activity of Traditionally Used Romanian .

Cherry stems (CS) represent a by-product intensively used in Eastern European countries as a traditional remedy for urinary tract disorders. Ethnopharmacological evidences sustain the use of CS as aqueous preparations (infusion and decoction), but few data were previously reported about phytochemical profile and pharmacological potential of CS hydroalcoholic extracts. In this regard, we aimed to evaluate the phenolic profile, antioxidant and tyrosinase inhibitory potential, and diuretic activity of 70% hydroethanolic cherry stems extract and cherry stems decoction (CSD).

Secondary metabolite contents and antimicrobial activity of leaf extracts reveal genetic variability of Vernonia amygdalina and Vernonia calvoana morphotypes.

Vernonia species (Asteraceae) are indigenous medicinal and food leaf vegetables commonly consumed in some African countries like Cameroon where they constitute a staple dish called "ndolé." Previous studies have demonstrated the nutritional importance of Vernonia, but there is little knowledge of their agronomic value and genetic potentials. Wide genetic variability in the genus has been established earlier through the study of its pollen.

Chemical Constituents and Biologic Activities of Sage Species: A Comparison between L., L. and .

Even though genus is one of the most known and studied taxa of Lamiaceae family, the knowledge regarding the chemical composition and health-related benefits of some locally used species (mostly endemic) is still scarce. In this regard, the present work aims to evaluate the chemical profile and potential bioactivities of 70% () ethanolic extracts obtained from the less-studied and in comparison with . HPLC-PDA analysis revealed the presence of rutin and catechin as the main compounds in the extracts of the three studied species (using the employed HPLC method), whereas the presence of naringenin was highlighted only in extract.

Antibacterial phloroglucinols derivatives from the leaves of Mallotus oppositifolius (Geisler) Müll. Arg. (Euphorbiaceae).

From the ethno-medicinally used leaves of Mallotus oppositifolius, four acylphloroglucinol derivatives, namely Acronyculatin SU (1-3) and Mallotojaponin D (4) were isolated along with seven known compounds (5-11). Structures were elucidated by comprehensive spectroscopic analyses and HRMS data. Absolute configurations were assigned by careful comparison of their specific optical rotation with those of closely related compounds.

Flavonoid Analysis and Antioxidant Activities of the L. Aerial Parts.

L. is the only species found in Romanian flora, being known as a remedy for inflammatory pathologies or for its hepatoprotective and adaptogen activities. The present investigation studied the flavonoid composition and antioxidant activities of the aerial parts of this species.

Flavonoid composition, cellular antioxidant activity and (myelo)peroxidase inhibition of a Bryonia alba L. (Cucurbitaceae) leaves extract.

Objectives: The aim of the present study consisted in the isolation of flavonoids from the leaves of Bryonia alba L. and evaluation of their antioxidant activity and inhibition on peroxidase-catalysed reactions.

Methods: Flavonoids were isolated by preparative HPLC-DAD and their structures were elucidated by MS and NMR.

Antioxidant capacity and polyphenolic content of the Echinocystis lobata (Michx.) Torr. et A.Gray flowers.

Comparative authentication of Hypericum perforatum herbal products using DNA metabarcoding, TLC and HPLC-MS.

Many herbal products have a long history of use, but there are increasing concerns over product efficacy, safety and quality in the wake of recent cases exposing discrepancies between labeling and constituents. When it comes to St. John's wort (Hypericum perforatum L.

Evaluation of Polyphenolic Content, Antioxidant and Diuretic Activities of Six Fumaria Species.

Romanian traditional medicine describes the use of aerial parts of species to treat hepatobiliary diseases as well as diuretic agents. The present study aims to investigate the chemical composition, antioxidant properties, and diuretic effects of several species. LC/MS analysis revealed that species contain phenolic acids and high amounts of flavonoids with rutin and isoquercitrin as main compounds.

Influence of Genista tinctoria L. or methylparaben on subchronic toxicity of bisphenol A in rats.

Objective: To evaluate the influence of an extract of Genista tinctoria L. herba (GT) or methylparaben (MP) on histopathological changes and 2 biomarkers of oxidative stress in rats subchronicly exposed to bisphenol A (BPA).

Methods: Adult female Wistar rats were orally exposed for 90 d to BPA (50 mg/kg), BPA+GT (35 mg isoflavones/kg) or BPA+MP (250 mg/kg).
