1. Arbutin has whitening, anti- age effects and UVB/ UVC filter by inhibiting tyrosinase and thus preventing the formation of melanin.
2. Normal skin microflora may increase the skin lightening effect of arbutin due to the antioxidant action of hydroquinone.
3. Arbutin has mutagenicity in mammalian cells after activation by human intestinal bacteria.
4. Arbutin has gastroprotective activities.
5. Arbutin is an anti-oxidant and a depigmenting agent, also has anti-inflammatory effect, it may be useful for treating the inflammatory and deleterious effects of BV2 microglial cells activation in response to LPS stimulation.
1. Oxyresveratro can inhibit tyrosinase activity.
2. Oxyresveratro is useful to trauma models, as toxicity to glia could be beneficial by inhibiting reactive gliosis.
3. 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.
4. Oxyresveratrol has neuroprotective effect, it can inhibit the apoptotic cell death in transient cerebral ischemia .
5. Oxyresveratrol , a dietary phenolic compound, as a potential nutritional candidate for protection against neurodegeneration in Parkinson disease.
6. 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.
7. Oxyresveratrol as an antibrowning agent for cloudy apple juices and fresh-cut apples.
1. Taxoquinone shows significant and concentration-dependent antioxidant and free radical scavenging activities of DPPH, nitric oxide, superoxide and hydroxyl free radicals by 78.83%, 72.42%, 72.99% and 85.04%, as compared to standard compounds ascorbic acid (81.69%, 74.62%, 73% and 73.79%).
2. Taxoquinone at the concentration range of 100-3,000 ug/mL and 200-1,000 ug/mL shows potent efficacy on inhibiting α-glucosidase and tyrosinase enzymes by 9.24-51.32% and 11.14-52.32%, respectively; suggests that taxoquinone could as a novel candidate in food and medicine industry as a natural alternative medicine to prevent diabetes mellitus type-2 related disorders and as a depigmentation agent.
3. Taxoquinone (100 ug/disc) displays potential anticandidal effect against Candia albicans.
