“…Sea buckthorn berries have been reported as a significant source of four to one-hundred times larger amounts of vitamin C than any other fruits (Makovics-Zsohár, Hegedus, Rédei, & Papp, 2014). Additionally, its other parts, such as leaves, twigs or roots, have been currently investigated to identify the content of important bioactive compounds and have been used for nutraceutical, pharmaceutical and cosmetic purposes (Jaroszewska & Biel, 2017; Makovics-Zsohár et al, 2014; Morgenstern, Ekholm, Scheewe, & Rumpunen, 2014; Perk, Ceylan, Yanar, Boztas, & Capanoglu, 2016).
