The presence of various phytochemicals in the concerned plant in the form of alkaloids, flavonoids, and terpenoids made it efficient anti inflammatory drug. The inhibition of hypotonicity induced HRBC membrane lysis was taken as a measure of the anti inflammatory activity. The percentage of membrane stabilisation for dichloromethane, ethyl acetate, methanol and water extracts of the plant (Root, Stem and Flower) and Diclofenac sodium were done at different concentrations. The percentage stabilization of stem water extract was found to be highest, followed by methanol extract of stem.

Extensive research on the domestication and rubber content of TK has demonstrated TK’s potential in industrial applications as a relevant natural rubber and latex-producing alternative crop. However, many aspects of its biology have been neglected in published studies. For example, floral development is still poorly characterized. TK inflorescences were studied by scanning electron microscopy. Nine stages of early inflorescence development are proposed, and floral micromorphology is detailed. Individual flower primordia development starts at the periphery and proceeds centripetally in the newly-formed inflorescence meristem.

Received: 6 March 2018; Accepted: 4 April 2018; Published: 7 April 2018 Abstract: Dandelion (Taraxacum officinale Weber ex F.H.Wigg.) has been used for centuries as an ethnomedical remedy. Nonetheless, the extensive use of different kinds of dandelion extracts and preparations is based on empirical findings. Some of the tissue-specific effects reported for diverse dandelion extracts may result from their action on intracellular signaling cascades. Therefore, the aim of this study was to evaluate the effects of an ethanolic dandelion root extract (DRE) on Ca2+ signaling in human embryonic kidney (HEK) 293 cells. The cytotoxicity of increasing doses of crude DRE was determined by the Calcein viability assay. Fura-2 and the fluorescence resonance energy transfer (FRET)-based probe ERD1 were used to measure cytoplasmic and intraluminal endoplasmic reticulum (ER) Ca2+ levels, respectively. Furthermore, a green fluorescent protein (GFP)-based probe was used to monitor phospholipase C (PLC) activation (pleckstrin homology [PH]–PLCδ–GFP).

Expansion of present agriculture practices into marginal land is not expected to solve the problem of increasing the food supply. New methods of feeding the ever increasing world population must be developed. The aim of the study was to evaluate the usefulness of the dandelion leaves as a source of supplemen- tal protein. Protein was extracted from the dandelion leaves by blending them after pH and moisture adjustment, squeezing the resultant pulp through filter press and coagulating the filtrate with acid and heat. The effects of pH, moisture content, pressure and temperature on the extractability and quality of protein were investigated. A mass balance was performed on dry matter and protein contents during the extraction steps. Proximate analysis was performed on the extracted leaf protein and the amino acid profile of the protein curd was determined.

  • Evaluating the Development and Potential Ecological Impact of Genetically Engineered Taraxacum Kok-Saghyz
    Evaluating the Development and Potential Ecological Impact of Genetically Engineered Taraxacum kok-saghyz DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Brian J. Iaffaldano Graduate Program in Horticulture and Crop Science The Ohio State University 2016 Dissertation Committee: Professor Katrina Cornish, Advisor Professor John Cardina Professor David Francis Professor Allison Snow Copyrighted by Brian J. Iaffaldano 2016 Abstract Natural rubber is a biopolymer with irreplaceable properties, necessary in tires, medical devices and many other applications. Nearly all natural rubber production is dependent on a single species, Hevea brasiliensis. Hevea has several disadvantages, including a long life cycle, epidemic diseases, and rising production costs which have led to interest in developing new sources of rubber with similar quality to Hevea. One species that meets this criterion is Taraxacum kok-saghyz (TK), a widely adapted species of dandelion that can produce substantial amounts of rubber in its roots in an annual growing period. Shortcomings of TK include an inability to compete with many weeds, resulting in poor establishment and yields. In addition, there is variability in the amount of rubber produced, plant vigor, and seed establishment. In order to address these shortcomings, genetic engineering or breeding may be used to introduce herbicide resistance and allocate more resources to rubber production. We have demonstrated stable transformation in Taraxacum species using Agrobacterium rhizogenes to introduce genes of interest as well has hairy root phenotypes. Inoculated roots were subjected to selection by kanamycin and glufosinate and allowed to regenerate into plantlets without any hormonal treatments or additional manipulations.

Ruderalia were chemically characterized in nutritional composition, sugars, organic acids, fatty acids and tocopherols. Furthermore, the antioxidant potential and phenolic profiles were evaluated in the methanolic extracts, infusions and decoctions. The flowers gave higher content of sugars, tocopherols and flavonoids (mainly luteolin O- hexoside and luteolin), while the vegetative parts showed higher content of proteins and ash, organic acids, polyunsaturated fatty acids (PUFA) and phenolic acids (caffeic acid derivatives and especially chicoric acid). In general, vegetative parts gave also higher antioxidant activity, which could be related to the higher content in phenolic acids (R2=0.9964, 0.8444, 0.4969 and 0.5542 for 2,2-diphenyl-1-picrylhydrazyl, reducing power, β-carotene bleaching inhibition and thiobarbituric acid reactive substances assays, respectively). Data obtained demonstrated that wild plants like Taraxacum, although not being a common nutritional reference, can be used in an alimentary base as a source of bioactive compounds, namely antioxidants.

  • Dandelion: for Such a Common Weed, Dandelion Is Easy to Misidentify
    Other Names: Taraxacum officinale, lion’s tooth, blow ball, fairy clock, Irish daisy Identifying Dandelion: For such a common weed, dandelion is easy to misidentify. Many look-alike plants have similar leaves, but dandelion leaves are nearly hairless. They have toothed edges, hence the French name, “dent de lion” or lion’s tooth. Leaves and hollow flower stems grow directly from the rootstock. What most people think of as a single dandelion flower is actually hundreds of flowers growing together on a single base. A “petal” is a complete flower. Dandelion flowering heads open in sunlight and close in dark rainy weather. Each dandelion can produce more than 5,000 seeds per year, which form “wish balls” that are carried away with the slightest breeze or breath. Individual seeds with parachute-like hairs have been known to travel on the wind as much as five miles! Dandelion only has one flowering head per stalk. Other look-alikes have many flowering heads per stalk. Dandelion roots, leaves and stems all exude a milky white sap. Dandelion belongs to the Asteraceae (sunflower) family. Where it Grows: The genus Taraxacum includes over 250 species that grow throughout the world. It will thrive just about anywhere including pristine mountain meadows, barren open fields, and even cracks in cement. Season: Leaves are gathered for food in early spring, and for medicine in spring through early summer. Buds and flowers are harvested in early to late spring depending on location and temperature. Roots are harvested in spring through autumn. How to Harvest: Every part of dandelion is useful.
