The methanol extract of heartwood of Artocarpus incisus showed potent 5 alpha-reductase inhibitory activity. We investigated the 5 alpha-reductase inhibitory effects of nine compounds isolated from A. incisus. Chlorophorin (IC50 = 37 microM) and artocarpin (IC50 = 85 microM) showed more potent
Twenty-four compounds, including the previously unknown artoxanthocarpuone A, artoxanthocarpuone B, hydroxylakoochin A, methoxylakoochin A, epoxylakoochin A, and artoxanthol, were isolated and characterized spectroscopically. Among them, artoxanthol is stilbene oligomer presumably constructed in a
The inhibitory effects of methanol extracts of heartwood of 23 Papua New Guinean wood species on tyrosinase activity were examined. The extract of Artocarpus incisus showed the strongest tyrosinase inhibitory activity which was equivalent to kojic acid. The extract apparently inhibited melanin
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 artocarpanone, norartocarpetin, artocarpesin, artogomezianol, andalasin, artocarbene, and chlorophorin showed tyrosinase
