Investigates the stimulation of melanogenesis by the hot water extract of adzuki beans (Vigna angularis) in cultured murine B16 melanoma cells and C3H mice. Indication that the distilled water fraction (WEx) can stimulate tyrosinase activity in cultured mouse B16 melanoma cells and hair color pigmentation in C3H mice; WEx stimulation of melanogenesis without inhibiting cell growth; Finding that WEx have pigmentation activity on hair color in C3H mice.

Examines the antimetastatic efficacy of hot-water extract from adzuki beans (EtEx.40) on experimental lung metastasis of murine B16 melanoma in mice. Cell proliferation; Assay for tumor invasion and migration; Cell adhesion assay; Gelatin zymography; Measurement of 1,1-diphenyl-2-picrylhydrazyl radical-scavenging activity.

Reports that a hot water extract obtained by boiling adzuki beans, Vigna angularis, to produce bean paste for Japanese cake showed inhibitory activity against alpha-glucosidase, alpha-amylase, maltase, sucrase, and isomaltase after HP-20 column chromatography. Preparation of the test materials; Oral glucose tolerance test on normal mice; Oral glucose tolerance test on rats with streptozotocin-induced diabetes.

The article presents a study which investigates the effect of theaflavins found in black tea on melanogenesis. It states that the various theaflavins were investigated by their effects on mouse B16 melanoma cells and assessed by melanin content. Moreover, the study reveals that TF-3, a component of theaflavins, mediated by tyrosine enzyme messenger ribonucleic acid (mRNA).
