Exploring lipophilic antioxidants accumulation in field-grown low temperature-stressed Ephedra monosperma
The seasonal patterns of changes in the content of lipophilic antioxidants $\beta$-carotene ($\beta$-Car), zeaxanthin (Zx), $\alpha$-tocopherol ($\alpha$-Toc), plastoquinone (PQ)/plastoquinol ($PQH_{2}$) were studied in the assimilating shoots of evergreen shrub Ephedra monosperma J.G. Gmel ex C.A....
