Introduction: Aristolochia ringens is a medicinal plant that has been used traditionally in the management of several diseases. Aim: This study focused on investigating phytochemical contents, mineral free radical scavenging, and alpha-amylase inhibitory activities (Vahl.) root Materials Methods: The materials were collected, dried, coarsely grounded, extracted using methanol. methanol extract ...

Trophic levels are critical for synthesizing species' diets, depicting energy pathways, understanding food web dynamics and ecosystem functioning, and monitoring ecosystem health. Specifically, trophic levels describe the position of species in a food web, from primary producers to apex predators (range, 1-5). Small differences in trophic level can reflect large differences in diet. Although tr...

There is an increasing demand for inexpensive and safe anesthetics that can reduce fish stress caused by some procedures such as capture and handling. In this context, the present study evaluated the potential of essential oils (EO) of three Brazilian native plants (Hesperozygis ringens, Lippia sidoides and Ocotea acutifolia) as anesthetics for the silver catfish Rhamdia quelen. Moreover, an an...

A new species in the genus Aristolochia (Aristolochiaceae), Aristolochia vallisicola T.L.Yao, from Peninsular Malaysia is described and illustrated. Among all Peninsular Malaysian Aristolochia,itis the only species with a pinnately veined lamina and a disc-liked perianth limb. A distribution map is provided and its conservation status is assessed as Least Concern.

INTRODUCTION Aristolochia belongs to the family Aristolochiaceae. In the indigenous system of medicine, the plant was used for the treatment of skin diseases, inflammation and purgative. Root extract was reported to have anti bacterial activity. A perennial climber shrub with woody base stocks. Leaves simple, alternate, entire, with undulate margins, acute; flowers greenish white, in auxiliary ...

ETHNOPHARMACOLOGICAL RELEVANCE Species of Aristolochia are associated with aristolochic acid nephropathy (AAN), a renal interstitial fibrosis and upper urinary tract cancer (UUC). Aristolochic acid nephropathy has been reported in ten countries but its true incidence is unknown and most likely underestimated. By combining an ethnobotanical and phytochemical approach we provide evidence for the ...

This study presents breeding and pollination systems of Aristolochia maxima and A. inflata in a seasonal tropical forest of Panama. Aristolochia is the most diverse genus of Aristolochiaceae, with ∼120 species distributed throughout the tropics and subtropics. All the Aristolochia species studied so far are pollinated by saprophagous flies of different families, which are presumably deceived by...

Aristolochia quangbinhensis T.V. Do, a new species from Central Vietnam, is described and illustrated. According to morphology, the species belongs to Aristolochia subgenus Isotrema. A detailed description, along with line drawings, photographs, ecology, distribution, conservation status as well as a comparison to morphologically similar species is provided.

Of the aspidogastrids Multicalyx cristata, Lobatostoma ringens, Cotylogaster basiri, and C. dinosoides sp. n., the last two had not been previously known from the Gulf of Mexico. The latter differs from other members of its genus by having relatively large equatorial marginal alveoli in comparison to those at the anterior and posterior ends of the holdfast. It also possesses extensive transvers...
