The Piper genus is the most representative of the Piperaceae reaching around 2000 species distributed in the pantropical region. In the Neotropics, its species are represented by herbs, shrubs, and lianas, which are used in traditional medicine to prepare teas and infusions. Its essential oils (EOs) present high yield and are chemically constituted by complex mixtures or the predominance of mai...

BACKGROUND The current study investigated the effects of Piper longumine on radio-sensitization of human breast cancer MDA-MB-231 cells and underlying mechanisms. MATERIALS AND METHODS Human breast cancer MDA-MB-231 cells were cultured in vitro and those in logarithmic growth phase were selected for experiments divided into four groups: control, X-ray exposed, Piper longumine, and Piper longu...

Piperaceae, a Latin name derived from Greek, which in turn originates from the Arabic word babary—black pepper, is considered one of the largest families of basal dicots, found in tropical and subtropical regions of both hemispheres. The species that belong to this family have a primarily pantropical distribution, predominantly herbaceous members, occurring in tropical Africa, tropical Asia, Ce...

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...
