Total phenols, flavonoids, minerals content and amino acids content were investigated in four fern species grown under four shading treatments with different transmittance of 35% full sunlight (FS), 13% FS, 8% FS and 4% FS. The four fern species contain high levels of total phenols and flavonoids, as well as abundant mineral elements and amino acids. The total phenols, flavonoids, minerals and amino acids content were strongly affected by transmittance, the total phenols and flavonoids content

Higher light intensity can effectively stimulate the synthesis of phenols and flavonoid, and proper shading can stimulate the accumulation of amino acids. In addition, Matteuccia struthiopteris (L.) Todaro (MS) had the highest total phenols content, Athyrium multidentatum (Doll.) Ching (AM) showed the highest total amino acids, total essential amino acids content, Osmunda cinnamomea (L) var. asiatica Fernald (OCA) exhibited the highest total non-essential amino acids content and flavonoids content, and Pteridium aquilinum L. Kuhn var latiusculum (Desy.) Underw. ex Heller (PAL) exhibited the highest minerals content. This will provide a scientific basis for the cultivation and management of four fern species.
