Antibacterial activity of six indigenous Indian plants: Acacia nilotica (Fabaceae), Albizia saman (Fabaceae), Azadirachta indica (Meliaceae), Carica papaya (Caricaceae), Cymbopogon citratus (Poaceae) and Mangifera indica (Anacardiaceae)

Plants have been used as major source of active compounds with medicinal importance since human civilization. These naturally occurring pharmacologically active agents have least or no toxicity to the host. The antibacterial activity of extracts (water, acetone and methanol) from six indigenous Indian plants: Acacia nilotica (Fabaceae), Albizia saman (Fabaceae), Azadirachta indica (Meliaceae), Carica papaya...

Growth promotion and elicitor activity of salicylic acid in Achillea millefolium L.

Salicylic acid (SA) is a phenolic compound present in plants and has multiple functions, including hormonal effect on stimulus of plant growth and development and induction of plant defense responses under conditions of biotic and abiotic stresses. Studies related to SA’s elicitor action on the synthesis of secondary metabolite in medicinal plants have been conducted in order to increase the economic value of...

Comparison of phenolic and volatile profiles of edible and toxic forms of Detarium senegalense J. F. GMEL

In Senegal, Detarium senegalense J.F. Gmel. (ditax in Wolof) is one of the most important ¶important forest fruit species. ¶However, exploitation of the edible fruit is based on local people’s knowledge. Only trees whose fruits are consumed by animals are exploited. ¶To identify them, a chemical comparison of edible and toxic forms was done in order to highlight differences between both forms....
