SUMMARY This paper discusses current aspects of improving the methodology for standardizing the roots of
Tangut rhubarb (Rheum palmatum L.). New approaches have been proposed for the quantitative analysis
of the content of anthracene derivatives in the roots of Tangut rhubarb, which consist in the use of
spectrophotometry at an analytical wavelength of 510 nm in terms of frangula-emodin, the use of
ultrasound to maximize the yield of anthracene derivatives from raw materials, and a reduction in the
extraction time in a water bath.
