1-Hydroxy-2-methylanthraquinone exhibits antimicrobial, antioxidant, pesticidal, and anti-inflammatory activities.

Enmein, 13-deoxy-19-hydroxy-, (19R)- is an Enmein-?type diterpene derivative and can be used in the preparation of antitumor drugs.

Dehydrocurdione, a zedoary-derived sesquiterpene, induces heme oxygenase (HO)-1, an antioxidative enzyme, in RAW 264.7 macrophages. Dehydrocurdione interacts with Keap1, resulting in Nrf2 translocation followed by activation of the HO-1 E2 enhancer. Dehydrocurdione suppresses lipopolysaccharide-induced NO release, a marker of inflammation. Anti-inflammatory activity.
