Prenylated stilbenoids are a unique class of natural phenolic compounds consisting of C6-
C2-C6 skeleton with prenyl substitution. They are potential nutraceuticals and dietary …

Hyperpigmentation is an abnormal darkening of the skin mostly derived from excessive
melanin production. It is typical of skin disorders including melasma associated to …

Biol. Pharm. Bull. 29(9) 1966—1969 (2006) Page 1 Tyrosinase (EC 1.14.18.1; PPO) is known to

Isoprenoid-substituted flavonoids were isolated from the wood of Artocarpus heterophyllus
by means of activity-guided fractionation. Artocarpin (1), cudraflavone C (2), 6 …

Dietary prenylated stilbenoids present in many food resources, and have good bioactivities.
However, their structure–activity relationships are rarely reported. In this work, eighteen C …

Prenylated stilbenoids are good candidates of nutraceuticals presented in food resources.
The levels of natural prenylated stilbenoids are usually low. Biotransformation is a promising …

Heartwoods of 22 African tropical wood species were extracted with methanol and the
contents of total phenolic compounds in these extracts were measured. Three bioassays …

Artocarpus plants have been a focus of constant attention due to the potential for skin
whitening agents. In the in vitro experiment, compounds from the Artocarpus plants, such as …

In our search for natural products from wood on cosmetics and drugs purposes and on the
basis of melanin biosynthesis assay guided fractionation, artocarpin was isolated from wood …

In our effort to find new whitening agents, we evaluated the effects of representative
chalcones [4-hydroxyderricin (1), xanthoangelol (2), xanthoangelol H (3) …
