Helichrysum arenarium (L.) Moench, belonging to the Asteraceae family, is known in traditional medicine for its diuretic, choleretic, and anti-inflammatory properties. This review focuses on the superiority of Helichrysum arenarium (sandy everlasting) over other known plants as a source of active pharmacological compounds used in complementary medicine to prevent digestive and hepatobiliary illnesses. Because the species exists both in spontaneous flora and in crops, this article highlights the development of a controlled culture of H. arenarium, following the reproducible quality of the plant as a biological material. The diversity of phytocompounds, especially well-characterized flavonoid extracts, and the differences between extraction procedures are discussed. Antiviral, antibacterial, and antifungal activities against human pathogens proved by different plant extracts and their mechanisms of action are analyzed. This study aims to contribute to the insufficient knowledge regarding the effects of Helichrysum species and to reveal that their extracts can be a valuable source for new active pharmaceutical ingredients.
The aim of the research was to determine to what extent the farinograph and alveograph parameters correlate with each other, and with the physical-chemical parameters, frequently used in the evaluation of wheat flours quality. Thus, 81 samples of wheat flours were analyzed. We found a better correlation of alveographic parameters, such as Extensibility and Mechanical Work (r2 varied between 0.48-0.51), with Protein content and Gluten content of flours, compared to farinographic parameters: Development time and Stability (r2 varied between 0.25-0.35). A poor correlation between farinographicand alveographic parameters was observed, the maximum value of the determination coefficient being r2=0.40, between Stability and Mechanical Work. The factorial analysis led to the highlight of four principal components. The first principal component was strongly correlated with the Protein content (including Gluten) of flours, with most farinographic (except for Water absorptin) and alveographic parameters (Mechanical work, W and Extensibility index, G). This component appears to express the tolerance of flours to the mechanical stress, exerted in the dough phase and their ability to preserve the own viscosity under mechanical stress conditions. The second principal component is related to the dough resistance to deformation, as expressed by the alveographic parameters Resistance and the P/L ratio. Principal components three and four were strongly correlated with flours ash (extraction degree) and amilolytic activity.
Basil is a plant known since ancient times for its properties (carminative, antiseptic), being considered a sacred plant. With the passage of time and with the diversification of assortments, basil was used for decorative and aromatic purposes, being considered a spicy plant. Red basil is also used in the perfume industry due to the pleasant aroma it possesses. Multiplication procedures were developed by in vitro cultures, using varieties of Romanian origin: 4 from red basil (lines: L9, L10, L11, L12) and 9 from green basil, characterized by special aromas and leaf shapes. When evaluating the germination yield, the percentages varied between 45-80% for aseptically inoculated red basil seeds on culture medium. And in the case of green basil varieties, the yield varied between 25 -100% after sowing in universal organic substrate. For the seeds of the green basil varieties, the sowing was performed in universal organic substrate, and the germination yield varied between 25 -100%. The types of explants taken from the resulting seedlings were represented by stems (fragments of hypocotyl and epicotyl), leaves and cotyledonary node. The induction of organogenesis was evaluated differently for each type of explant under the effect of phytohormones such as cytokinins (TDZ and BAP) added in concentrations of 0.5-2 mg / L to the basal culture medium MS / 1962. After 3 subcultures of the explants on the culture medium recipes (45 days), the organogenic yields expressed in vitro were compared
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
