[Quality and quantity determination of brassino-steroid hormones by HPLC and related assay in some supplement capsules]

ABSTRACT

Background: Brassino-steroids as hormonal plants are of the most important components that have shown the biological effects. These compounds may be act as inducer of growth in the plant and their concentrations is increased under some stress conditions. Such clinical studies show that these hormones have also anabolic activities similar to the human anabolic hormones hence, may be administrated as supplements in athletes. Their increasing consumption as supplement suggests introducing a precise and accurate analytical method for determination of brassinosteroids in pharmaceutical dosage forms and also in some biological fluids
