(3R,5R)-1-(4-Hydroxyphenyl)-7-phenyl-3,5-heptanediol is an antiemetic found in Alpinia officinarum that significantly inhibits copper sulfate-induced emesis in young chicks (with an inhibition rate of 50.9% at a dose of 20 mg/kg and 37.7% at a dose of 50 mg/kg).

7-hydroxycoumarinyl-γ-Linolenate is a γ-linolenic acid ester of 7-hydroxycoumarin (umbelliferone) that behaves as a substrate for cPLA2. Hydrolysis of 7-hydroxycoumarinyl-γ-linolenate by phospholipase results in the release of the fluorescent compound 7-hydroxycoumarin which can be monitored spectrophotometrically (excitation at 335 nm, emission at 450 nm).
