Nowadays, various branches from food industry generate large amount of by-products that are often underutilized, which could have negative environmental impact and increase the price of the raw material as it is not completely utilized in the production. Mixtures of two interesting plants (yarrow and rose hip) with different ratios, obtained as by-products from filter-tea factory, have been extracted with organic solvents and with environmentally friendly technology, supercritical fluid extraction (SFE). In the obtained extracts, quantitative content of minor plant pigments (chlorophylls and carotenoids) was determined and technologies were compared. Moreover, the effect of SFE parameters on yields of chlorophylls and carotenoids was determined. The results showed that SFE could be used as a good alternative for extraction of plant pigments from Achillea millefolium L. and Rosa canina L. mixtures. Besides plant pigments, the obtained extracts were rich in other nonpolar compounds from plant mixtures. Utilization of herbal waste provided value-added products, rich in various health benefit compounds.
