Withanolides from Physalis hispida.
Nine new withanolides (1-9), withahisolides A-I, were isolated along with nine known compounds (10-18) from the aerial parts of Physalis hispida. The structures of 1-9 were elucidated through a variety of spectroscopic techniques, while the structures of 1 and 2 were confirmed by X-ray crystallographic analysis. Compounds 1-3 are the first withanolides with nonaromatic six-membered ring D moiet...
متن کاملAntimicrobial Studies on Methanol Extract of Benincasa Hispida Cogn., Fruit
The methanol extract of wax gourd, the fruits of Benincasa hispida cogn.(Cucurbitaceae) was found to show no inhibition against three gram positive bacteria Staphylococcus aureus, Staphylococcus epidermidis, and Bacillus subtilis and three gram negative bacteria Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia by cup-plate method whereas antifungal studies showed significant in...
متن کاملCadmium toxicity to ringed seals (Phoca hispida)
Cadmium concentrations in kidneys from ringed seals (Phoca hispida) from North West Greenland (Qaanaaq) are high. Concentrations range at level known to induce renal toxic effects (mainly tubulopathy) and demineralisation (osteopenia) of the skeletal system (Fanconi’s Syndrome) in humans as well as laboratory mammals. We have studied possible cadmium induced histopathological changes in the kid...
متن کاملEffects of Patch-Size on Populations of Intertidal Limpets, Siphonaria spp., in a Linear Landscape
Organisms with different life-histories and abilities to disperse often utilise habitat patches in different ways. We investigated the influence of the size of patches of rock (separated by stretches of sand) on the density of pulmonate limpets (Siphonaria spp.) along 1500 km of the linear landscape of the South African coastline. We compared the influence of patch-size on two congeneric specie...
متن کاملDiversity of Indo-West Pacific Siphonaria (Mollusca: Gastropoda: Euthyneura).
Species of the limpet genus Siphonaria (Gastropoda: Euthyneura) are commonly found in the rocky intertidal, worldwide, except in the Arctic. In total, 205 species-group names are available and not permanently invalid. However, estimating the actual species diversity of Siphonaria has remained challenging, mainly because past authors have interpreted differently the variation of shell characters...
