Nepeta glomerulosa Boiss. is a medicinal plant has been used in traditional medicine. The aim of this study was to evaluate the anti-melanogenesis inhibitory activity of MeOH, n-hexane, ethyl Acetate (EtAc), dichloromethane (CH2Cl2), n-butanol (BuOH) and H2O extracts isolated from N. glomerulosa in B16 melanoma cell line. The B16F10 cell line viability after treatment with increasing concentrat...

The genus Rhanterium (Asteraceae) is a widely distributed medicinal plant throughout western North Africa and some species are used in folk medicine. aim of research was to investigate methanolic extracts from different parts (flowers, leaves, stems) Tunisian suaveolens as potential sources bioactive products useful for healthy purposes. In particular, were analyzed the phenolic composition the...

Bioactivity-guided isolation of a crude extract from a culture broth of Bacillus sp. has led to the isolation of (-)-4-hydroxysattabacin (1). The inhibitory effect of (-)-4-hydroxysattabacin (1) was investigated on melanogenesis in the murine melanoma cell line, B16F10, and human melanoma cell line, MNT-1, as well as a pigmented 3D-human skin model. (-)-4-Hydroxysattabacin treatment decreased m...

In the present study, olive leaf extract, harvested from four seasons, extracted with solvent (methanol and water), was treated by D101 and Sephadex LH-20, and divided into 10 fractions by TLC detection. The antioxidant activity was evaluated using DPPH, superoxide anion scavenging and reducing power assays. Tyrosinase inhibitory activity was also performed with L-DOPA as substrate. On extracti...

The plant Cardaria draba (L.) Desv. subsp. (Brassicaceae), is traditionally used for various ailments in different cultures. We investigated solvent extracts such as methanol, ethanol, and water obtained from flowers, leaves, stems, roots of C. their chemical composition, well antioxidant enzyme inhibition activities acetylcholinesterase (AChE), butyrylcholinesterase (BChE), ?-glucosidase, ?-am...

OBJECTIVES In food industry, the inhibition of tyrosinase is very important, because this enzyme catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones, which contribute in undesirable color and taste of fruits and vegetables. Teucrium polium L. var. gnaphalodes (Lamiaceae), a wild-growing flowering plant that has many applications in food preparations and tr...

In this study, in order to explore the anti-melanogenic effect of PFE (Paederia foetida L. extract) and suggest its availability, B16F10 cells, which are murine melanoma were stimulated with alpha-Melanocyte-stimulating hormone (α-MSH) conduct an vitro experiment. Treatment cells activated melanogenesis due stimulants showed that significantly inhibits melanin content as well intracellular tyro...

Berberine, an isoquinoline alkaloid, has a wide range of beneficial properties, including anti-bacterial, anti-inflammatory, anti-cancer, and cholesterol-lowering effects. Recently findings suggest that berberine improves glucose and lipid metabolism disorders. In the present study, we examined the mechanism underlying the inhibitory effect of berberine on α-melanocyte-stimulating hormone (α-MS...

Synthetic compounds that are used in the clinic to regulate skin hyperpigmentation, such as arbutin, hydroquinone, and kojic acid, are only moderately effective. But, their use is limited by side effects. As part of an effort to overcome the limitations, we developed resveratrol-enriched rice (RR) using genetic engineering technique. Each of resveratrol and rice has been reported to produce ant...
