The anthocyanin composition of five purple leaves cultivars of Ocimum basilicum L. was investigated by reversed-phase HPLC with mass-spectrometric detection by ESI mode with ion partial fragmentation as well as preparation of dried differently colored forms of anthocyanins encapsulated into maltodextrinmatrix. Analysis of the mass spectra revealed that according to the chromatographic profile the set of basil cultivar anthocyanins under investigation may be divided into two groups with the common feature being ahigh level of acylation with (mainly) p-coumaric, ferulic and malonic acids of the same base: cyanidin-3-dihexoside-5-hexoside. The presence of acylation with substituted cinnamic acids permits us to obtain solutions not only with a red color (the property of the flavylium form) but also with blue shades of coloration due to quinonoid and negatively charged quinonoid forms. All forms except that of flavylium are not stable in solution but stable enough to prepare dried encapsulated forms by lyophilization. Although the loss of anthocyaninswith drying is not negligible, the final product is characterized with high stability for storage in a refrigerator.

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.

Regenerative forms of higher education are emerging, and required, to connect with some of the grand transition challenges of our times. This paper explores the lived experience of 21 students learning to navigate a regenerative form of higher education in the Mission Impact course at The Hague University of Applied Sciences. This semester-length course ran for two iterations with the intention of connecting the students with local transitions towards a more circular society, one where products are lasting and have multiple lives when they are shared, refurbished, or become a source for a new product. At the end of each iteration, the students reflected on their experience using the Living Spiral Framework, which served as basis for an interpretative phenomenological analysis of their journey navigating this transformative course. The results of this study include four themes; (1) Opting in—Choosing RHE, (2) Learning in Regenerative Ways, (3) Navigating Resistance(s), and (4) Transformative Impacts of RHE. These themes can be used by practitioners to design and engage with regenerative forms of higher education, and by scholars to guide further inquiry. van den Berg B, Poldner KA, Sjoer E, Wals AEJ. ‘Sweet Acid’ An Interpretative Phenomenological Analysis of Students’ Navigating Regenerative Higher Education.
