Antioxidant bibenzyl derivatives from Notholaena nivea Desv.
Four new bibenzyl derivatives were isolated, together with other known bibenzyls, by bioassay-guided fractionation of a CHCl₃-MeOH extract of Notholaena nivea Desv. (Pteridaceae) aerial parts. The structures were elucidated by NMR, ESIMS and other spectral analyses. Their antioxidative effects towards superoxide, lipidic peroxidation and the 2,2'-azino-bis-3-ethilbenzothiazoline-6-sulfonic acid...
متن کاملNutritive value of the winged bean (Psophocarpus palustris Desv.).
I . The winged bean (Psophocarpus palustris Desv.) has been grown successfully for several seasons, on an experimental basis, in the forest belt of Ghana, where earlier attempts to grow the soya bean had proved unsatisfactory. 2. Although botanically different, the composition of the dry seeds was found to be very similar to that of the soya bean, containing 37.3 yo protein, 18.1 Yo fat, 13.9 p...
متن کاملMolecular Cytogenetic Analysis of Deschampsia antarctica Desv. (Poaceae), Maritime Antarctic
Deschampsia antarctica Desv. (Poaceae) (2n = 26) is one of the two vascular plants adapted to the harshest environment of the Antarctic. Although the species is a valuable model for study of environmental stress tolerance in plants, its karyotype is still poorly investigated. We firstly conducted a comprehensive molecular cytogenetic analysis of D. antarctica collected on four islands of the Ma...
متن کاملAntioxidant Responses Induced by UVB Radiation in Deschampsia antarctica Desv.
Deschampsia antarctica Desv. is one of two vascular plants that live in the Maritime Antarctic Territory and is exposed to high levels of ultraviolet-B (UVB) radiation. In this work, antioxidant physiology of D. antarctica was studied in response to UVB induced oxidative changes. Samples were collected from Antarctica and maintained in vitro culture during 2 years. Plants were sub-cultured in a...
متن کاملEffect of insulin on Blattela germanica Linnacus.
OBJECTIVE To determine the sensitivity of Blattela germanica L (B. germanica L) to differenct doses of insulin. METHODS B. germanica were reared in laboratory conditions at (25±2) °C and (50±5)% relative humidity (RH), and exposure period of 12:12 L/D. Different concentrations, viz. 5, 10, 15, 20 and 25 µ of insulin N, R, (N+R) were prepared and injected to 10 treated cockroaches with another...
