Hamaudol is a chromone isolated from Saposhnikovia divaricata. Hamaudol shows significant inhibitory activity on cyclooxygenase (COX)-1 and COX-2 activities with IC₅₀ values of 0.30, 0.57 mM, respectively, and has potent analgesia and anti-inflammary effects.

Hamaudol (Compound 7) increases the potency to exhibit a potent analgesia at doses of 1, 5 and 10 mg/kg in mice, although it do not show clear dose dependency.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.
