BACKGROUND Pycnocycla spinosa Decne. ex Boiss is an aromatic plant which showed relaxant effects on isolated ileum contractions and antidiarrheal activity. Thirty four components have been extracted from P. spinosa essential oil, of which several major constituents were found to show seasonal variation. OBJECTIVES The aim of this work is to evaluate the diurnal variation of its oil constituen...

Plants that belong to the Combretaceae family have long history of use in the traditional medicine systems of Africa and Asia for treatment of diseases and conditions associated with HIV/AIDS-opportunistic infections. The objective of this study was to investigate the biological activities of extracts of Terminalia stenostachya Engl. & Diels and Terminalia spinosa Engl. (Combretaceae), to verif...

Background:Oncoba spinosa, an endangered medicinal plant whose secondary metabolites have not been extensively profiled, and which is hitherto yet to be examined for cytotoxicity, is being investigated in this study. Methods: Leaves of Oncoba spinosa (800 g) were extracted with 95% aqueous methanol. The crude extract was partitioned with n-hexane and the resultant defatted extract was extensive...

Scolus secretions and hemolymph of caterpillars of Saturnia pyri fed with two different foodplants (Crataegis monogyna, Prunus spinosa) were chemically analyzed and their chemical similarities determined. The secondary-compound patterns obtained for the two body fluids showed no significant differences when compared between the two groups of alternatively fed last-instar larvae. Thus, the compo...

A new species of Phallocryptus Biraben 1951 (Branchiopoda, Anostraca) from Mongolia is described. Phallocryptus tserensodnomi sp. nov. is close to P. spinosa (Milne-Edwards 1840), but both morphological and molecular analyses (Cytochrome Oxidase I, COI) indicate that they represent separate species. Most relevant differential features of the new species include: (1) frontal appendage provided w...

Methanol and aqueous extracts from fi ve plant species, used in traditional medicine in Guatemala for the treatment of microbial infections, were tested in vitro for their ability to scavenge DPPH, OH(.) and O(2) (-) radicals and to inhibit lipoperoxidation (LPO) in order to establish a relationship between their antioxidant activities and their effects against infectious agents. Acalypha guate...

Populations of the South-western part of Morocco traditionally use the fruits of Argania spinosa (L.) Skeels to prepare an edible oil whose obtainment furnishes, as side product, a cake used to feed the cattle and complemented the forage furnished by the leaves and fruits of this same plant. However, the wood of A. spinosa is also used for fuel and the subsequent induced deforestation is nowada...

OBJECTIVE To observe morphology of Auchenacantha galeopteri (A. galeopteri), Auchenacantha spinosa (A. spinosa) and Auchenacantha parva (A. parva) from Sukabumi and Ujung Kulon, Indonesia using scanning electron microscopy (SEM). METHODS Specimens for light microscopy examination were fixed with warm 70% alcohol, cleared and mounted in lactophenol for wet mounting. Drawings were made with the...

over Bengal and the North-Western Provinces. In the latter place it is somewhat scarce in the hot weather, as it dries up by exposure to the powerful rays of the sun, but even then it can be found out there in shady places. In Bengal it is constantly found every where. Cows and rabbits are very fond of the leaves. In milking cows some people believe that it increases the secretion of milk. In t...
