Studies were conducted to broaden the systematic knowledge of genus Duranta erecta L., contribute a better understanding their taxonomic and evolutionary relationships. Previous studies have pointed out complexity in taxonomy nomenclature species. A total 224 samples collected from six geo-political zones Nigeria, grouped into 38 accessions. The plants compared using 21 morphological characters...

The present study reveals the pharmacological action of Serjania erecta Radlk. (Family Sapindaceae), an important medicinal plant species used in the Brazilian Pantanal against gastric pain. The methanolic (Me) and chloroformic (Se) extracts obtained from leaves of S. erecta were challenged by a very strong necrotizing agent in rodents, absolute ethanol. Se was also confronted with a nitric oxi...

The mutational origin and subsequent evolution of de novo genes, which are hypothesized to be genes of recent origin that are not obviously related to ancestral coding sequence, are poorly understood. However, accumulating evidence suggests that such genes may often function in male reproduction. Here we use testis-derived expressed sequence tags (ESTs) from Drosophila yakuba to identify genes ...

Significant increases in upa armigera in a wind-tunnel were obtained with air entrained headspace samples of African marigold, Tagetes erecta, flowers (P=0.014), and sweet pea, Lathyrus odoratus, flowers (P=0.047). Identification of the compounds contained in the Porapak Q extracts was done by GC-MS. Direct EAG was used to screen for the most electrophysiologically active natural extracts and G...

The flowers of African marigold (Tagetes erecta L), a medicinal plant widely cultivated in Thailand, were subjected to evaluation for total phenolics, DPPH scavenging and thiobarbituric acid-reactive substance (TBARs) assays as well as tyrosinase inhibitory activity. In preliminary studies, the ethyl acetate (EA) extract obtained by continuous extraction showed the highest activities with highe...
