Mutualistic and Endophytic Microorganisms of Artemisia Annua: Description, Role and Use

Publié en ligne: 08 Jun 2020
Pages: 5 - 21

Résumé

Abstract

Artemisia annua is an important medical plant that produces artemisinin used for its antimalarial, antibacterial and antifungal effects in modern medicine. The high demand and low artemisinin content in plants (0.01-2 %) has led to studies about alternative methods to increase yield. Biofertilizers (beneficial microbes and/or biological products that colonize roots, improve plant nutrition and growth) have been reported affecting secondary metabolism and the production of active ingredients of herbs. The purpose of this paper is to draw attention to the current status of the research on mutualistic and endophytic microorganism of A. annua that have the potential to increase the quality and quantity of the crude drugs, derived from the herb. Scientific papers in this field focus on the effects on inoculation with different microorganisms (arbuscular micorrhizal fungi, endophytic bacteria and fungi) and the isolation of endophytes from A. annua. Bioinoculants can affect biomass, artemisinin and essential oil concentration, disease resistance, nutrient status, phosphatase activity, foliar glandular trichome density, leaf chlorophyll content, guaiacol peroxidase enzyme concentration, stomatal conductance and transpiration rate, and plant growth parameters (total weight, leaf yield, height, seed yield). The endophytes isolated from the plant are potential artemisinin content and plant stress resistance enhancers.

The Medicinal Importance of Wild Plants from the Surroundings of Ulieş Village, Mureş County

Publié en ligne: 08 Jun 2020
Pages: 22 - 34

Résumé

Abstract

The village of Ulieş belongs to Râciu Commune. It is located in the south-eastern part of the Transylvanian Plain (N46°41’30” E24°23’56”) in a hilly region crossed by wide valleys. It is situated at 24 km distance from Tîrgu Mureș, in the contact area of Mădăraş Hills and Comlod Hills, on the middle stream of the Comlod River (or Lechința) and its tributaries. The paper aims were the study of the flora from the surroundings of Ulieş Village, the investigation of possible medicinal use of the encountered plants species, and the preservation of plant diversity from the area. Fieldworks were conducted in 2014-2017. A total of 415 vascular plant taxa belonging to 76 families were identified. From these, 185 species are medicinal plants with certain content of active principles. Plants containing tannins (13.51%) were in higher percentage followed by those with essential oils (12.97%), saponins (10.81%), alkaloids (8.10%), flavonoids (7.56%), coumarins (7.02%), mucilages (5.94%), iridoids (5.40%), phenolic glycosides (3.78%), anthraquinone derivatives and cardiotonic glycosides (3.24), organic acids, vitamins and provitamins (3.78%), bitter principles (2.70), bitter-aromatic principles (2.16%), etc.

The Herbarium Files of Gyula Erazmus Nyárády which Got Abroad

Publié en ligne: 08 Jun 2020
Pages: 35 - 41

Résumé

Abstract

The herbarium of Gyula Erazmus Nyárády has been assessed to contain around 90.000 sheets. During the past thirty years, the legacy of the famed botanist still found in public institutions and private collection across Romania and Hungary has been studied and processed by Kálmán Váczy, Sándor Bartha and especially Katalin Bartók. However, nothing is known about the sheets that had ended up outside Hungary or Romania. This study proposes to fill this gap to some extent: firstly, it draws attention to sheets from Nyárády’s herbarium found in the inventory of the world’s biggest botanical gardens, museums and universities of natural science; secondly, it goes into details about the circumstances of collecting the prepared taxa, and the conclusions that can be drawn from this; it presents the reasons why some sheets got abroad; and it adds more data to reconstruct Nyárády’s social network. It also indicates that the heritage, now known to consist of around 90.000 sheets, can be completed with the sheets found abroad.

Hemp Shives as Natural Amendments in Crops of Rapeseed (Brassica napus) and Flax (Linum usitatissimum)

Publié en ligne: 08 Jun 2020
Pages: 42 - 52

Résumé

Abstract

The aim of this study is to evaluate the possibility of using hemp shives as natural amendments in a phytoremediation sequence. Thus, plant growth tests were conducted for rapeseed (Brassica napus) and flax (Linum usitatissimum) in vegetation pots with sandy soil. These were seeded in a cadmium artificial contaminated environment with or without hemp shives. The efficiency of hemp shives as natural amendments was evaluated after 40 days of initiating experimental model, by evaluation of plant growth and development of plants through biometric and gravimetric measurements. Also, the concentration of assimilatory pigments was determined. In order to establish bioaccumulation capacity, degree of recovery and translocation factor, it was determined the concentration of cadmium metal ions absorbed in various parts of rapeseed and flax plants. It has been found that the development of the root system is more pronounced in the presence of hemp shives both in contamination with cadmium ions and in the absence. By determining cadmium concentrations accumulate in various parts of the plant have been shown that supplementing growth media with hemp shives, improves the bioaccumulation process of cadmium ions. According to the results, the hemp shives can be used as amendments in phytoremediation process, enhancing bioaccumulation process.

Ferulic Acid – A Versatile Molecule

Publié en ligne: 08 Jun 2020
Pages: 53 - 60

Résumé

Abstract

The review summarizes the main roles of ferulic acid (4-hydroxy-3-methoxy-cinnamic acid), a phenolic compound widespread in the vegetable world, being present in cereals (rice, wheat, oats), coffee, tomatoes, nuts or corn, but also in a range of plants used in Traditional Chinese Medicine. It plays a vital role in ensuring cell wall rigidity and also in the formation of other important organic compounds for plants. Ferulic acid has a wide variety of biological activities such as: antioxidant, anti-inflammatory, antimicrobial, antiallergic, anticancer, antithrombotic, antiviral activities, vasodilator, hepatoprotective and metal chelation actions, enzymatic activity modulation, and wound healing activity. The most important action is the antioxidant one, being studies that demonstrate that ferulic acid acts synergistically with other antioxidants. Also, the antioxidant effect of ferulic acid is enhanced by skin exposure to ultraviolet light, making it a good ingredient for sunscreen cosmetics. It is one of the most powerful natural antioxidant that has the potential to neutralize free radicals, to slow down the aging process of the skin, to accelerate skin regeneration, to heal the skin wounds and also to preserve the health and beauty of the skin.

Isoflavonoids − Dual Action on Estrogen Receptors

Publié en ligne: 08 Jun 2020
Pages: 61 - 67

Résumé

Abstract

Isoflavonoids are phytoestrogenic compounds found mainly in plants from the Fabaceae family and also in soy-based foods. Isoflavonoids exhibit (anti)estrogenic effects, acting on estrogen receptors due to the structural similarities with estrogenic hormones (17β-estradiol). The aim of our minireview is to highlight the pharmacokinetic and pharmacodynamic properties of isoflavonoids, in order to sustain the beneficial effects in different pathologies (osteoporosis associated with menopause, breast cancer, prostate cancer, protective cognitive functions) but, at the same time, to aware about the possible adverse effects on long-term administration.
