摘要

The extracts from various types of Camelina sativa plant biomass (camelina seedcake, in situ and in vitro plants) and seedcake-derived lignin solution were prepared. Their composition was characterized using high-performance liquid chromatography (HPLC) and matrix-free or matrix-assisted laser desorption/ionization mass spectrometry (LDI/MALDI MS). The antioxidant/antiradical activity of the extracts was studied using Folin–Ciocalteu method and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The ability of the extracts to inhibit the biodiesel oxidation and to affect the processes of dichromate ions reduction was evaluated. HPLC and LDI/MALDI MS results suggest that all the extracts contain such phenolic compounds as flavonoids (mainly rutin and other quercetin glycosides), hydroxycinnamic and hydroxybenzoic acids. The total phenolic content in the extracts decreased in the following row: seedcake > in situ > in vitro > lignin solution, being in correlation with the DPPH radicals scavenging activity. The camelina seedcake extract, which contained the largest amount of phenols (795.5 mg L−1), was found to effectively decelerate the biodiesel oxidation. Despite the low phenolic content (47.0 mg L−1), the extract from camelina in vitro plant showed the highest hole scavenging capacity in dichromate ion photocatalytic reduction processes. Thus, camelina plant biomass is a promising source of phenolic compounds for various applications.
