Reversed-phase HPLC with mass spectrometric and diode array detection as well as some literature data were used to reveal the individual types of solutes in anthocyanin complexes of tulip flower petals that are responsible for tulip flower petals coloration of the samples available in the local flower market. It has been found that the main components of the complexes are 3-rutinosides and their 2”’ and 3”’ acylated with acetic acid derivatives of the three anthocyanidins - delphinidin, cyanidin and pelargonidin in the color dependent ratios, though trace quantities of 3-glucosides were found in some cases. For the anthocyanin structure confirmation a correlation analysis of solute retentions of cyanidin or pelargonidin derivatives vs that of delphinidin was proposed based upon equivalence of structures alteration in the solute pairs for each series. The specificity of solutes retention modes was revealed by relative retention analysis, the trend parameters reflected particularities of chromatographic behavior as well as that of electron spectra of the solutes. The difference of acylated anthocyanins retentions was proposed to disclose the conformation states of solutes in the sorbent interface.

Human and plant relationships are described within the rich tradition of multispecies ethnography, ethnobotany, and political ecology. In theorizing this relationship, the issues of functionalism, and interconnectivity are raised. This article aims to re-examine the position of plants in the context of contemporary urban spaces through the prism of environmental ethics. Despite conceptual plurality and socio-cultural complexity of human–plant relationships, social scientists fail to note how the perception of ‘greenery’ has objectified plants in urban environment. Without seriously considering bioethics, theories of human–plant relationship might fail to note exploitive anthropocentric relationship between humans and plants in urban spaces. The article is inspired by reflections of urban flora in Amsterdam, The Netherlands. https://doi.org/10.1016/j.scs.2013.01.007 https://www.linkedin.com/in/helenkopnina/

In human-controlled environments and in cultivated landscapes, the plants accommodate social, cultural and economic needs. This article will focus on the use of plants for agriculture, urban planning, forestry, environmental education and indoor decoration in The Netherlands. This exploration, based on literature review and observations, reveals mostly anthropocentric, instrumental and unsustainable practices. In urban landscapes, plants are pushed to the margins, if not entirely eradicated. This article shows that the moral recognition of plants is an ethical imperative, which is also critically important in order to achieve environmental sustainability. In line with ecocentric ethics and in the interest of long-term sustainability, this article suggests an alternative, more ethical and sustainable ways of relating to plants in The Netherlands and beyond. This is an Accepted Manuscript of an article published by Taylor & Francis in "Journal of Urbanism: International Research on Placemaking and Urban Sustainability" on 10/11/18 available online: https://doi.org/10.1080/17549175.2018.1527780 LinkedIn: https://www.linkedin.com/in/helenkopnina/

The nursing home is often a final stage in the living career of older persons, but the question remains whether it is a true home or merely a place where care is provided for the residents. This study investigates the sense of home and its constituent factors among both permanent and temporary residents of nursing homes in The Netherlands. A qualitative research design was chosen for the study, which consisted of in-depth interviews using a topic list that was developed through literature review and a focus group session. Autonomy and safety and security are the basic aspects for a sense of home. These aspects refer to the relationships and actions of nursing home residents and the environment in which people live. The research findings show that developing a sense of home encompasses much more than just being surrounded by personal belongings and having a private room with certain facilities. Subjective components of relationships and (inter)actions are as important as the physical component of living and housing. Only when a right balance is achieved between all factors, a true sense of home, albeit away from the familiar home someone spent most of his/her life, can be developed. Understanding these perspectives and needs can contribute to a better design and retrofitting process of future nursing homes.

In de huidige landbouwsector worden grote hoeveelheden gewasbeschermingsmiddelen gebruikt, wat leidt tot hoge kosten voor telers. De verwachte aanscherping van wetgeving dwingt de industrie om efficiëntere spuitmethoden te onderzoeken. Een veelbelovende oplossing is het implementeren van precisiespuiten, die niet alleen het gebruik van chemicaliën vermindert, maar ook kostenbesparingen oplevert en kan voldoen aan strengere milieuwetgeving. De technologie achter precisiespuiten maakt gebruik van real-time data, verzameld door camera's op de spuit, of van taakkaarten waarvoor van tevoren het land is in gescand. Beide mogelijkheden hebben verschillende kosten en besparingen. Hoewel er momenteel onvoldoende concrete data beschikbaar is om definitieve conclusies te trekken, wordt verwacht dat met een toename van het aantal precisiespuiten op het land betrouwbaardere resultaten kunnen worden verkregen. Op de lange termijn lijkt de aanschaf van een real-time precisiespuit aantrekkelijk, vooral voor grotere telers. De ontwikkeling die gepaard gaan met het verzamelen van meer data zal ook een beter inzicht geven in de effecten van precisiespuiten op de gewaskwaliteit, wat van belang is voor het berekenen van de effecten op de kosten.

Production of dry encapsulated forms of anthocyanins from tulip petals with high antioxidant activity and their utilization in lipsticks.Anthocyanins (of the Greek anthos = flower and kianos = blue) are the most important pigments of the plants. These pigments are responsible of the shiny orange, pink, red, violet and blue colors in the flowers and fruits of some plants. The most interesting substances of the waste material are anthocyanins as natural water soluble antioxidants with a great health benefit besides the coloring properties. Tulip is a perennial bulbous plant which is popular worldwide and especially in the Holland due to the showy flowers of the great variety of colors and shades. It was found that for flowers of different colors biosynthesis of anthocyanins of the three anthocyanidin backbones may occur. Thus, pelargonidin (Pg), cyanidin (Cy) and delphinidin (Dp) derivatives, are responsible for tulip flowers color.

Chemical preservation is an important process that prevents foods, personal care products, woods and household products, such as paints and coatings, from undesirable change or decomposition by microbial growth. To date, many different chemical preservatives are commercially available, but they are also associated with health threats and severe negative environmental impact. The demand for novel, safe, and green chemical preservatives is growing, and this process is further accelerated by the European Green Deal. It is expected that by the year of 2050 (or even as soon as 2035), all preservatives that do not meet the ‘safe-by-design’ and ‘biodegradability’ criteria are banned from production and use. To meet these European goals, there is a large need for the development of green, circular, and bio-degradable antimicrobial compounds that can serve as alternatives for the currently available biocidals/ preservatives. Anthocyanins, derived from fruits and flowers, meet these sustainability goals. Furthermore, preliminary research at the Hanze University of Applied Science has confirmed the antimicrobial efficacy of rose and tulip anthocyanin extracts against an array of microbial species. Therefore, these molecules have the potential to serve as novel, sustainable chemical preservatives. In the current project we develop a strategy consisting of fractionation and state-of-the-art characterization methods of individual anthocyanins and subsequent in vitro screening to identify anthocyanin-molecules with potent antimicrobial efficacy for application in paints, coatings and other products. To our knowledge this is the first attempt that combines in-depth chemical characterization of individual anthocyanins in relation to their antimicrobial efficacy. Once developed, this strategy will allow us to single out anthocyanin molecules with antimicrobial properties and give us insight in structure-activity relations of individual anthocyanins. Our approach is the first step towards the development of anthocyanin molecules as novel, circular and biodegradable non-toxic plant-based preservatives.
