Alkaloids and anthraquinones of Hemerocallis fulva var. kwanso roots and their PTP1B inhibitory activity

Key Points

• PTP1B inhibitory activity reached 85% inhibition at 100 µg/mL concentration, highlighting the potency of the extracts.
• Alkaloids and anthraquinones were isolated from the roots and tested for their biochemical effects on PTP1B.
• The study method involved bioassays to determine the effectiveness of the extracted compounds.
• These findings may support the development of new therapeutic strategies targeting PTP1B-related diseases.
