What tocopherols and tocotrienols are found in Hypericum perforatum L. inflorescences?

Label:chem

Topic
Hypericum perforatum L. (St. John’s Wort) is a medicinal herb used in traditional and modern phytochemical drugs. It is commonly used to produce phloroglucinol (hyperforin, adhyperforin), naphtodianthrone (hypericin), and xanthone compound extracts for cosmeceuticals and the treatment of mild-moderate depression. The study investigates the presence of tocopherols and tocotrienols in H. perforatum inflorescences and their extraction efficiency using different hydroethanolic solutions.

From: "Tocopherol and tocotrienol homologue recovery from Hypericum perforatum L. and extraction residues after hydroethanolic extraction", Industrial Crops and Products, Volume 224, February 2025, 120321
Answer
The study found that H. perforatum inflorescences contain tocopherols (Ts) and tocotrienols (T3s), with δ-T3 (45%) and α-T3 (19%) being the main tocotrienols, and α-T (24%) and γ-T (7%) being the main tocopherols. The presence of tocotrienols in H. perforatum inflorescences is significant, making it a novel source of these compounds.
