Protosappanin B possesses antitumor, anti-inflammation and anti-oxidation properties, it protects PC12 cells against oxygen–glucose deprivation-induced neuronal death by maintaining mitochondrial homeostasis via induction of ubiquitin-dependent p53 protein degradation.

Monocrotaline is a pyrrolizidine alkaloid.

Plumbagin is a hydroxy-1,4-naphthoquinone that is 1,4-naphthoquinone in which the hydrogens at positions 2 and 5 are substituted by methyl and hydroxy groups, respectively. It has a role as a metabolite, an antineoplastic agent, an anticoagulant and an immunological adjuvant. It is a hydroxy-1,4-naphthoquinone and a member of phenols.

Lycorine is a toxic crystalline alkaloid found in various Amaryllidaceae species that weakly inhibits acetylcholinesterase (AChE) and ascorbic acid biosynthesis.Lycorine has antiviral, and anti-cancer effects, the mechanisms of Lycorine on the multiple myeloma cell line ARH-77 are associated with G1 phase cell cycle arrest, mitochondrial dysfunction, reactive oxygen species (ROS) generation, ATP depletion, and DNA damage.

Haplopine shows photo-activated antimicrobial activity against S. aureus. It exhibits potent melanogenesis-inhibitory activities with almost no toxicity to the cells. Haplopine is an organic heterotricyclic compound, an organonitrogen heterocyclic compound and an oxacycle.

The alkaloid Narciclasine is the bioactive compound responsible for the anti-inflammatory action of HCE. Narciclasine displays marked proapoptotic and cytotoxic activity, as does pancratistatin, and significant in vivo anticancer effects in various experimental models, but it is also associated with severe toxic side effects. Narciclasine acts on the auxin signaling pathway upstream of TIR1, which modulates Aux/IAA protein degradation, and thereby affects the auxin-mediated responses in Arabidopsis roots, inhibits the root hair development of lettuce seedlings. Narciclasine is a natural product found in Narcissus pseudonarcissus. It has a role as a metabolite.

Rhodojaponin II correlates pretty well with cardiotoxicity.

Parthenolide exhibits anti-cancer, anti-inflammatory, immunomodulatory, anti-Leishmania, and antimigraine effects, it inhibits nociception and neurogenic vasodilatation in the trigeminovascular system by targeting the TRPA1 channel.Parthenolide is also an inhibitor of the nuclear factor-kappaB pathway, can ameliorate cardiovascular derangement and outcome in endotoxic shock in rodents. (1Ar,7aS,10aS,10bS)-1a,5-dimethyl-8-methylidene-2,3,6,7,7a,8,10a,10b-octahydrooxireno[9,10]cyclodeca[1,2-b]furan-9(1aH)-one is a germacranolide.

Rubiadin is a dihydroxyanthraquinone that is anthracene-9,10-dione substituted by hydroxy groups at positions 1 and 3 and a methyl group at position 2. It has been isolated from Rubia yunnanensis. It has a role as an antioxidant, an antibacterial agent, a hepatoprotective agent and a plant metabolite. Rubiadin has hepatoprotective, antioxidant, and antitumor promoting effects. Rubiadin can decrease bone loss through the inhibition of osteoclast formation,differentiation and bone resorption.

Purpurin is one of the natural colorants extracted from madder roots and other Rubiaceae family plants. Purpurin is a novel specific inhibitor of Adipocyte-derived leucine aminopeptidase, it exhibits anti-angiogenic, antifungal, antibiotic, and antioxidative activities. Purpurin is a trihydroxyanthraquinone derived from anthracene by substitution with oxo groups at C-9 and C-10 and with hydroxy groups at C-1, C-2 and C-4. It has a role as a biological pigment, a plant metabolite and a histological dye.

Acitretin has immunomodulatory effect, and low dose acitretin therapy is safe, well tolerated and partially effective in chemoprophylaxis of skin cancer in renal transplant recipients, it for chemoprevention of non-melanoma skin cancers in renal transplant recipients. Acitretin dramatically improves the results of UV-B treatment in patients with severe psoriasis and it markedly decreases the effective cumulative UV-B dose. Acitretin in the treatment of severe lichen sclerosus et atrophicus of the vulva. Acitretin therapy is effective for psoriasis associated with human immunodeficiency virus infection. All-trans-acitretin is a retinoid, an acitretin and an alpha,beta-unsaturated monocarboxylic acid. It has a role as a keratolytic drug.

Gnetol significantly suppresses melanin biosynthesis in murine B16 melanoma cells, it has a strong inhibitory effect on murine tyrosinase activity. Gnetol is active in the inhibition of arachidonic acid (AA)-induced platelet aggregation.Gnetol has the IC(50) value of 1.3 uM towards butyrylcholinesterase and shows a reversible and competitive inhibition in the kinetic study.

Gallotannin is a class of hydrolysable tannins obtained by condensation of the carboxy group of gallic acid (and its polymeric derivatives) with the hydroxy groups of a monosaccharide (most commonly glucose). It is functionally related to a gallic acid.
