Pothomorphe umbellata Extract Prevents α-Tocopherol Depletion After UV-irradiation

Abstract: In this work we evaluated the influence of topical application of P. umbellata root extract gel, containing 0.1% of 4-nerolidylcathecol, on the antioxidant network in UV-induced oxidative damage in hairless mouse skin. The UV-irradiation had no influence on ascorbic acid levels or on the antioxidant enzyme (superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase) activities, but topical P. umbellata treatment protected alpha-tocopherol from being depleted after UV-irradiation. alpha-To… Show more

“…The variation in the concentration of the major substance, trans-nerolidol, which is an isoprene unit of phenylpropanoid 4-nerolidylcathecol-4NC (Bergamo et al, 2005), is important because nowadays it is a target of cosmetics industries due to its high antioxidant activity providing protection against skin problems induced by sun radiation (Ropke et al, 2003) and it must be clearified the concentration. The concentration of phenylpropanoid 4-nerolidylcathecol-4NC increased with light and was higher in plants cultivated under full sun.…”

“…Atualmente, o extrato de suas folhas é comercializado por empresas de cosméticos na forma de composições dermocosméticas tópicas para antienvelhecimento, devido às atividades antioxidante e fotoprotetora comprovadas cientificamente nesta espécie, atribuída ao fenilpropanóide 4-nerolidilcatecol (Ropke et al, 2003), além de outras atividades farmacológicas atribuídas a esta espécie, tais como tratamento de epilepsia (Coimbra & Silva, 1958), disfunção hepática, bronquite asmática, cicatrizante e antiinflamatório (De Feo, 1991), febrífugo (Di Stasi et al, 1993), sedativa e analgésica (Hammer & Johns,1993), repelente de insetos (Chartol, 1964), anti-malária (Amorim et al, 1988).…”
