Pectolinarigenin possesses anti-inflammatory, antiallergic and hepatoprotective activities.It is a dual inhibitor of COX-2/5-LOX,and the IC50 >1 microM; it also can increase activity levels of GSH, GR, GCS, and GST, as well as SOD. Pectolinarigenin is a dimethoxyflavone that is the 6,4'-dimethyl ether derivative of scutellarein. It has a role as a plant metabolite. It is a dimethoxyflavone and a dihydroxyflavone. It is functionally related to a scutellarein.

Rhododendrol is an inhibitor of melanin synthesis developed for lightening/whitening cosmetics, it can competitively inhibit mushroom tyrosinase and serve as a good substrate, while it also shows cytotoxicity against cultured human melanocytes at high concentrations sufficient for inhibiting tyrosinase. (+)-Rhododendrol and epi-rhododendrin have anti-inflammatory effect, they can suppress the NO production by activated macrophages in vivo.

p-Coumaric acid ester has moderate free radical scavenging ability.

Viscumneoside III is a viscumneoside that is homoeriodictyol in which the hydroxy group at position 7 has been converted into the corresponding beta-D-glucopyranoside, the 2-hydroxy group of which has been converted to its beta-D-apiofuranoside derivative. Found in Viscum coloratum, an evergreen hemiparasitic plant whose stems and leaves are used in traditional Chinese medicine for the treatment of rheumatism. It has a role as a plant metabolite. Viscumneoside III demonstrates high tyrosinase inhibition, it can be utilized in skin whitening cosmetics.

6-Hydroxykaempferol is a competitive inhibitor of tyrosinase compared to L-DOPA, it shows also high antioxidant activities.

Silydianin, an active constituent of Silybium marianum, has inhibitory effect on on the in vitro production and release of oxidative products. Silydianin has possible antiinflammatory activity, which regulates caspase-3 activation, affects cell membranes and acts as a free radical scavenger.

Oxyresveratrol , a dietary phenolic compound, has neuroprotective effect, as a potential nutritional candidate for protection against neurodegeneration in Parkinson disease; Oxyresveratrol has antioxidant activity, can reduce neuronal oxidative damage and protect hepatocytes against oxidative stress and mitochondrial dysfunction, which may be associated with activation of Nrf2, it also as an antibrowning agent for cloudy apple juices and fresh-cut apples. Oxyresveratrol exhibits a potent inhibitory effect on dopa oxidase activity of tyrosinase which catalyzes rate-limiting steps of melanin biosynthesis.Oxyresveratrol exhibits the inhibitory activity at the early and late phase of viral replication and inhibited the viral replication with pretreatment in one-step growth assay of HSV-1 and HSV-2.

Deoxyarbutin possesses a potent ability in skin lightening and antioxidation with less melanosome cytotoxicity, it is an effective hypopigmentation agent, it is widely used in skin lighting. Deoxyarbutin can combate tumour in vitro and in vivo by inhibiting the proliferation and metastasis of tumour via a p38-mediated mitochondria associated apoptotic pathway.

Cephaeline is a pyridoisoquinoline comprising emetam having a hydroxy group at the 6'-position and methoxy substituents at the 7'-, 10- and 11-positions. It is a conjugate base of a cephaeline(2+). It derives from a hydride of an emetan. Cephaeline was highly active against protected primary CLL cells (relative IC50's 35 nM ) and acted by repressing HIF-1α and disturbing intracellular redox homeostasis.

Mulberroside F shows inhibitory effects on tyrosinase activity and on the melanin formation of melan-a cells, it also exhibits superoxide scavenging activity that is involved in the protection against auto-oxidation, suggests that mulberroside F may be used as a skin whitening agent.

Schisanhenol has antioxidative effect on human LDL oxidation, may be through scavenging free radicals; it also has anti-apoptosis effect on BACSs, may be related to its inhibition of ROS generation. Schisanhenol can protect against adriamycin induced heart mitochondrial toxicity.

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.
