Zerumbone is a natural monocyclic sesquiterpene first isolated from rhizomes of the wild ginger Z. zerumbet.It has also been shown to have anti-oxidant and anti-inflammatory activities, contributing to immunomodulatory and hepatoprotective effects.

(E)-3,4,5-Trimethoxycinnamic acid (O-Methylsinapic acid) is a natural compound derived from the roots and rhizomes of Notopterygium incisum.

Parishin (Parishin A) A is isolated from the rhizomes of Gastrodia elata. It has good neuroprotective effects against brain disorders.

7-O-MethylMangiferin is an xanthone isolated from the rhizomes of Iris nigricans.

Orcinol glucoside (Sakakin) (OG), an active constituent isolated from the rhizomes of Curculigo orchioides Gaertn, shows potent antioxidative and anxiolytic activities without sedative effects.

Protogracillin, a steroidal saponin isolated from Dioscorea zingiberensis Wright (DZW), may inhibit platelet aggregation (PAG) and thrombosis, potentially reducing the risk of cardiovascular diseases through its anti-thrombotic action.

The biological activity of Jervine (Jerwiny) is mediated via its interaction with the 7 passes transmembrane protein Smoothened. Jervine binds with and inhibits smoothened, which is an integral part of the Hedgehog signaling pathways. With smoothened inhibited, the GLI1 transcription cannot be activated and Hedgehog target genes cannot be transcribed.

Cycloposine, a steroidal alkaloid present in the roots and rhizomes of Veratrum californicum, is known to possess teratogenic properties.

(-)-Afzelechin, an antioxidant compound extracted from the rhizomes of Astilbe rivularis, demonstrates potent activity [1].

Norbergenin is a chemical compound. It is the O-demethylated derivative of bergenin. It can be isolated from rhizomes of Bergenia stracheyi.

Polyphyllin H can be extracted from loblolly pine and rhizomes, has antitumor activity, and is used in studies of inflammation, fractures, and convulsions.

Dactylorhin A, a succinate derivative ester isolated from the rhizomes of Gymnadenia conopsea, exhibits a moderate inhibitory effect on nitric oxide (NO) production in RAW 264.7 macrophage cells.

Iristectorigenin A is a natural isoflavone isolated from the rhizomes of B. chinensis [with antioxidant activity].

Kaempferol-7,4'-dimethyl ether, isolated from the rhizomes of Zingiber phillipseae, exhibits antioxidant activity against S. aureus and E. coli with MICs of 200 and 225 μg ml, respectively.

Diphenylheptane A (DHPA), isolated from the rhizomes of the plant Curcuma longa L., is a phenolic dialog compound with antimicrobial activity.
