Mulberroside F (104) showed moderate inhibitory effects on tyrosinase activity and on the melanin formation of melan-a cells. It also exhibited superoxide scavenging activity that is involved in the protection against auto-oxidation [62]. The geranylated stilbenes 81 and chlorophorin from Chlorophora excelsa [51], prenylated ones 4-prenyloxyresveratrol and artocarbene (72) from Artocarpus incisus [528] all demonstrated tyrosinase inhibitory activity (ICso 96, 1.3, 0.66 and 2.45 //M, respectively). [Pg.610]

Chlorophorin is a prenylated tetrahydroxystilbene of the West African hardwood iroko (Chlorophora excelsa) (72). This wood is durable and resembles teak or oak. It is used for both outdoor and indoor constructions. The wood cannot be varnished or surface treated with lacquer since the chlorophorin, like many other 2- and 4-hydroxysubstituted stilbenes, prevents proper hardening of the polyester. Workers exposed to saw dust of iroko wood develop strong allergic reactions that have been ascribed to the chlorophorin content of the wood (56) (see also Chap. 9.5). [Pg.517]

The African woods used in the terrestrial exposure, Pterocarpus erinaceus (10), Ongokea gore (9), Nauclea diderrichii (8), Chlorophora excelsa (9), and Erythrophleum ivorense (8) were identified and supplied by the Forest Products Research Institute (FPRI) of Ghana Eusideroxylon zwageri (12) was obtained from Malaysia. The parenthesized numbers... [Pg.75]
