Neo-rehmannioside is a carotenoid glycoside that can be isolated from the dried roots of Rehmannia glutinosa.

2-Deethoxy-2-hydroxyphantomolin, Germacranolide, is an Antifungal and Antibacterial agent. 2-Deethoxy-2-hydroxyphantomolin can be isolated from Elephantopus tomentosus Linn and E. mollis. 2-Deethoxy-2-hydroxyphantomolin is moderately active against Candida albicans (14 mm clearing zone) and slightly active against Escherichia coli (12 mm), Pseudomonas aeruginosa (12 mm), Bacillus subtilis (14 mm), and Trichophyton mentagrophytes (13 mm).

Linalool is a natural monoterpene which is a competitive NMDA receptor antagonist. Linalool is orally active and crosses the blood-brain barrier. Linalool has anticancer, antibacterial, anti-inflammatory, neuroprotective, anxiolytic, antidepressant, anti-stress, cardioprotective, hepatoprotective, nephroprotective and pulmonary protective activities.

Citronellol ((±)-Citronellol) is an orally active inducer of apoptosis. Citronellol can prevent oxidative stress, mitochondrial dysfunction, and apoptosis in the SH-SY5Y cell Parkinson's disease model induced by 6-OHDA by regulating the ROS-NO, MAPK/ERK, and PI3K/Akt signaling pathways. Citronellol can induce necroptosis in human lung cancer cells through the TNF-α pathway and accumulation of ROS. Citronellol can reduce the levels of LC-3 and p62 to regulate the autophagy pathway, inhibit oxidative stress and neuroinflammation, and thus have neuroprotective effects on Parkinson's rats. Citronellol exhibits anti-fungal activity against Trichophyton rubrum by inhibiting ergosterol synthesis.

Micheliolide is a sesquiterpene lactone with anti-cancer and anti-inflammatory effects, which is derived from Michelia compressa and Michelia champaca. Micheliolide can attenuate high glucose-stimulated NF-κB activation, IκBα degradation, and the expression of MCP-1, TGF-β1, and FN in mouse mesangial cells. Micheliolide inhibits LPS (HY-D1056)-induced activation of NF-κB and PI3K/Akt/p70S6K pathways to play an anti-inflammatory role. Micheliolide inhibits dextran sodium sulphate (DSS) (HY-116282)-induced inflammatory intestinal disease, colitis-associated cancer and rheumatic arthritis.

Camphor ((±)-Camphor) is a topical anti-infective and anti-pruritic and internally as a stimulant and carminative. However, Camphor is poisonous when ingested. Antiviral, antitussive, and anticancer activities. Camphor is a TRPV3 agonist.

L-Perillaldehyde is a major component in the essential oil containing in Perillae Herba. Inhalation of L-Perillaldehyde shows antidepressant-like activity through the olfactory nervous function.

Pulegone is a monoterpene ketone compound widely present in the essential oils of many plants. Pulegone can also be used as a bird repellent. Pulegone has multiple activities such as anti-inflammatory, antibacterial, antifungal, and anti-hyperalgesic effects. Pulegone is particularly effective against bacteria of the Salmonella species.

Umbellulone is an active constituent of the leaves of Umbellularia californica. Umbellulone stimulates the TRPA1 channel in a subset of peptidergic, nociceptive neurons, activating the trigeminovascular system via this mechanism.

Benzoylpaeoniflorin is an orally active monoterpene glycoside compound. Benzoylpaeoniflorin exerts anti-inflammatory, anti-allergic, psoriasis-improving and sepsis-improving effects by inhibiting signaling pathways such as TNF/NF-κB and MAPK, as well as regulating immune homeostasis. Benzoylpaeoniflorin can be used in research related to immune, allergic and inflammatory diseases.

γ-Terpinene, a monoterpene, is an orally active antioxidant compound which can scavenge radicals directly. γ-Terpinene has potent antinociception activity. γ-Terpinene exhibits antimicrobial efficacy against various bacteria and fungi.

Myrcene (β-Myrcene) is a type of aromatic compound that inhibits TNFα and NF-κB activity. Myrcene has anti-invasive action, inhibits cell cycle, and leads to cancer cell apoptosis. Myrcene has strong blood protection effect, anti-inflammation, and anti-inflammatory activity.

α-Phellandrene (alpha-Phellandrene) is an orally active monoterpenoid and insecticide. α-Phellandrene can be isolated from plant essential oils. α-Phellandrene induces Apoptosis and Autophagy. α-Phellandrene promotes cAMP signaling pathway and increases NO production. α-Phellandrene has anti-inflammatory and anticancer (sarcoma) activities. α-Phellandrene shows insecticidal activity against Lucilia cuprina L3. α-Phellandrene reduces mechanical hyperalgesia.
