Anthocyanins of Macedonian grape pomace from three varieties “Pinot noir”, “Merlot” and “Vranec” were isolated

by high speed countercurrent chromatography. After purification of the fractions by means of preparative high

performance liquid chromatography the structures of isolated pigments were elucidated by electrospray ionization

multiple mass spectrometry (ESI-MSn) and nuclear magnetic resonance (NMR) spectroscopy. The major anthocyanin

malvidin-3-glucoside and the minor pigments delphinidin-3-glucoside, cyaniding-3-glucoside, petunidin-3-glucoside,

and malvidin-3-p-coumarоyl-glucoside were isolated.

The “Color activity concept” was applied and visual detection thresholds of isolated anthocyanins were

determined. The results of the “color activity value” of the isolated pigments and their detection thresholds were in

good agreement with the color shade of the different varieties of red grape pomace

According to the concept of historical responsibility, the commitments of individual countries to take action on climate change are distributed based on the relative effects of their past emissions as manifested in present climate change. Brazil presented a comprehensive version of the concept to pre-Kyoto negotiations in 1997. The ‘Brazilian proposal’ originally combined several justice principles; however, following referral to the Subsidiary Body for Scientific and Technological Advice, discussion soon became confined to technical calculations. This case illustrates how disparities in knowledge production and framing can influence the inclusiveness of negotiations. Southern participation in the policy process was restrained due to lack of scientific expertise on the part of Southern countries and due to the non-inclusive biophysical discourse traditionally preferred by Northern policy-makers. The historical responsibility issue became stranded on problems of how to correctly represent physical nature in climate models. This marginalized the original intention that equity should be the guiding principle of the North–South interaction, arguably undercutting a potential angle of approach to advance the climate change negotiations. The article concludes that in the interest of facilitating the North–South dialogue in climate change negotiations, any framing of historical responsibility that excludes equity needs to be redefined.Original publication: Mathias Friman and Björn-ola Linnér, Technology obscuring equity: historical responsibility in UNFCCC negotiations, 2008, Climate Policy, (8), 339-354.http://dx.doi.org/10.3763/cpol.2007.0438.
