An EtOH extract of fruits of Piper longum was found to exhibit a potent inhibitory effect
against α-melanocyte-stimulating hormone (α-MSH)-induced melanin production in B16 …

In this study, the antimelanogenic activity of piperlongumine in murine B16F10 melanoma
cells and zebrafish was investigated, and its mode of antimelanogenic action was elucidated …

MATERIALS AND METHODS Materials Air-dried leaves, stems and rhizomes of P.
methysticum were purchased at Fiji crude drugs market in 2004. Leaves, stems, rhizomes …

In the course to find compounds that inhibit melanin biosynthesis (ie, whitening agents), we
evaluated the effects of the methanol-soluble fraction (ie, the water-soluble portion of …

We investigated the effects of compounds isolated from a methanolic extract of rose hips on
melanin biosynthesis in B16 mouse melanoma cells and the possible mechanisms …

Biol. Pharm. Bull. 28(7) 1229—1233 (2005) Page 1 Gray hair is caused by a genetic
predisposition, aging, decrement of melanocytes by environmental stress, and decrement of …

MATERIALS AND METHODS Materials P. nigrum leaves cultivated in Thailand were
purchased from Thailand. The sample was identified by Prof. M. Mizuno, Gifu …

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

During the course of screens to identify anti-melanogenic agents from natural resources, we
found that the methanol extract of the dried flower of Inula britannica L. inhibited melanin …

We compared the inhibitory effects on melanogenesis of six plant parts (leaves, stems, roots,
whole fruits, calyxes, and fruits without calyxes) of Cucumis sativus. MeOH extracts of leaves …
