The present investigation aims at assessing the hepatoprotective effect of triterpene fraction isolated from the stem bark of Wrightia tinctoria (containing lupeol, β-amyrin and β-sitosterol) on CCl4-induced hepatotoxicity in the rat. CCl4 (1.5 mg/kg, i.p) is a potent hepatotoxic agent which causes peroxidative degeneration of membrane lipids with the potential outcome of fatty degeneration. Th...

In this work, Isatis tinctoria hairy root cultures (ITHRCs) were established as an alternative source for flavonoids (FL) production. I. tinctoria hairy root line V was found to be the most efficient line and was further confirmed by the PCR amplification of rolB, rolC and aux1 genes. Culture parameters of ITHRCs were optimized by Box-Behnken design (BBD), and eight bioactive FL constituents (r...

Most research on the genetics of invasive plant species has focused on analyzing spatial differences among existing populations. Using a long-established Gunnera tinctoria population from Ireland, we evaluated the potential of using plants derived from seeds associated with different soil layers to track genetic variation through time. This species and site were chosen because (1) G. tinctoria ...

The present study deals with isolation, taxonomic characterization and biological activity of medicinal mushroom Ganoderma spp. The results of the present study Ganoderma sp. DKR1 and Ganoderma sp. DKR2 were isolated from two hard woods of Casurina equiestifolia and Morinda tinctoria respectively in Cuddalore district, Tamil Nadu, India. The Ganoderma isolate were characterized for macro and mi...

This study aimed to investigate the effects of wild indigo (Baptisia tinctoria) root extract as a functional food material, in terms antioxidant and skin health-related activities. Both water ethanol (50/50, v/v) extracts showed high phenol content. They were evaluated for activity, such 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2?-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), protect...

Piper hispidinervum (C. DC.), Piperaceae, is a promising source of sassafras oil, the source of safrol, currently derived from endangered plants of the Lauraceae such as Ocotea pretios Ness (Mez.), Cinamomum petrophilum, C. mollissimum, and Sassafras albidum Nutt. The essential oil of P. hispidinervum contains high levels (83–93%) of safrole in leaves which can be easily extracted by hydrodisti...

drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of iran. detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. six wild populations of anthemis tinctoria, were assigned to four drought treatments, i.e. well-watered ...

We study zeros of the L-functions L(f, s) of primitive weight two forms of level q. Our main result is that, on average over forms f of level q prime, the order of the L-functions at the central critical point s = 1 2 is absolutely bounded. On the Birch and Swinnerton-Dyer conjecture, this provides an upper bound for the rank of the Jacobian J0(q) of the modular curve X0(q), which is of the sam...
