OBJECTIVE To examine the anti-bacterial activity of leaf extracts of Morus alba L. (Moraceae) and Piper betel L. (Piperaceae), and seed extracts of Bombax ceiba L. (Borabacaceae). METHODS We have partially purified plant extracts by solvent extraction method, and evaluated the effect of individual fractions on bacterial growth using Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aerug...

Random amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) analysis were applied to 74 individual plants of Piper spp in Hainan Island. The results showed that the SRAP technique may be more informative and more efficient and effective for studying genetic diversity of Piper spp than the RAPD technique. The overall level of genetic diversity among Piper spp ...

The anti-amoebic effects of crude methanol extracts of Piper longum fruit, Piper sarmentosum root and Quercus infectoria nut gall against Entamoeba histolytica infecting the caecum of mice were studied. Caecal amoebiasis in mice was induced by injection of Entamoeba histolytica trophozoites directly into the caecum. The mice were then treated orally with the extract, a standard drug (metronidaz...

Medicinal plant extracts prepared with various selected solvents from four species, Glycyrrhiza glabra, Piper bittle, Azadirachta indica and Moringa olifera, were screened for animicrobial activity by using well diffusion method. Plant extracts showed strong antimicrobial action against microbes, among the plant extracts the extracts of Piper bittle shows maximum antimicrobial activity against ...

Peganum harmala and Piper longum medicinal herbs are used in traditional medicine to treat various diseases and to relieve tragic processes. The chemical composition of these two compounds is their analgesic agent. The purpose of this study was the Peganum harmala and Piper longum rubbing oil effect on pain in male mice by using formalin test. In this study, male mice were divided into three gr...

Title:Mechanism of Piper laetispicum extract (EAE-P) during Chronic Unpredictable Mild Stress is mediated by the interrelationship of inflammatory cytokines, apoptosis cytokines and neurotrophin in the hippocampus

Cowpea is major source of dietary protein in tropical region of the world and damage caused by Callosobruchus maculatus impact negatively on its economic and nutritional values. In Nigeria today, the use of synthetic insecticides has been the major means of protecting stored grains from insect pest infestation. The drawback associated with the use of insecticides has necessitated the search for...

Thailand is located in the tropical rain forest zone above the equator. This geographically supports very rich biodiversity, including the genus Piper (Piperaceae). Thirtyeight species of Piper, from out of over 1,000 species in the world, have been discovered recently (1998-2006) by the authors. Plant morphology and plant use information were recorded via observation, market surveys, and inter...

INTRODUCTION The phytochemistry of species of the genus Piper has been studied extensively, including Piper solmsianum. However, no studies have addressed the phytochemistry of the sap content of Piper species. OBJECTIVE To evaluate the transferring of secondary compounds from the saps of P. solmsianum to the honeydew of Edessa meditabunda. METHODOLOGY The honeydew of E. meditabunda and sap...
