Sideritis species have been known as medicinal plants since ancient times, and used as tea in Mediterranean countries such as Turkey, Greece and Spain. They are also used for the treatment of several ailments such as a cough, common cold and gastrointestinal disorders. The aim of the present study was to perform the chemical composition, antioxidant, anticholinesterase and anti-tyrosinase activ...

Dopamine is one of the important medications of Portulaca oleracea L. To optimize the production of dopamine, one of the methods is the identification and engineering of metabolite pathways. To investigate the tyrosine decarboxylase (TDC) and tyrosinase, which seem to be the most important genes in dopamine synthesis pathway, hairy roots were produced from Portulaca oleracea using Agrobacterium...

skin and hair, and is synthesized in melanosomes transferred from melanocytes. Although melanin plays an important protective role against UV light, over production and accumulation of melanin pigment it could create serious skin problems such as freckles, age spots, and melasma. Thus, the inhibition of melanogenesis has been the focus of medicinal and cosmetic treatments for skin depigmenting ...

Phenolic compounds are valuable cosmetic ingredients. They display skin protective potential and play an important role in preserving formulations due to their ability neutralize free radicals. Considering this fact, the current study aims obtain a phenolic-enriched fraction from Arbutus unedo for topical application cosmeceutical products. The chemical composition antioxidant, anti-inflammator...

melanin pigment plays a critical role in camouflage and   protection against harmful effects of solar radiation. melanogenesis is under   complex regulatory control by multiple agents. tyrosinase is a   multifunctional, which catalyzes the first two steps in mammalian   melanogenesis. in this study, inhibitory effects of astragalus fasciculifolius   and astragalus gypsicolus on diphenolase acti...

We already reported that genetically engineered resveratrol-enriched rice (RR) showed to down-regulate skin melanogenesis. To be developed to increase the bioactivity of RR using calli from plants, RR was adopted for mass production using plant tissue culture technologies. In addition, high-pressure homogenization (HPH) was used to increase the biocompatibility and penetration of the calli from...
