in traditional medicine,some plants have been used as analysics.the aim of this investigation was to evaluate the analgesic effect of two plants,piper nigrum and Zingiber officinale that are used  traditionally to relieve headache,rheumatic arthritis,and toothache.for this purpose the methanolic extract of zingiber and piper nigrum,in different doses,were injected intraperitonealy to mice and t...

Black pepper (Piper nigrum L.) is the most widely used spice in the world. Blackening is considered to be beneficial and important in the processing of black pepper because it contributes to its color and flavor. The purpose of this paper is to investigate polyphenol oxidation as well as the chlorophyll and vitamin C (VC) degradation in the blackening of Piper nigrum L. Black pepper was produce...

Piperine, a major alkaloid in black pepper is one of the most promising bioenhancers till date. Other methods used for its extraction suffer drawbacks such as poor extraction efficiency, tedious and expensive isolation methodology, piperine photodegradation, etc. Hence a simple, rapid and efficient method has been developed for the isolation of piperine from the fruits of Piper nigrum. The meth...

B lack pepper from the Piper nigrum L. vine (Figure 1) is the most commonly used spice worldwide, and its extracts have been used as a folk medicine in a variety of cultures. Piper nigrum is used for the production of both black pepper (from the unripened fruit) and white pepper (from the dehulled mature berry).

Methanol extracts from 27 medicinal plant species were tested at concentrations of 0.5, 1 and 2 mg/mL for their in vivo fungicidal activities against six phytopathogenic fungi. Their efficacy varied with plant pathogen, tissue sampled and plant species. Very strong fungicidal activity was produced by extracts of Boswellia carterii, Saussurea lappa, Glycyrrhiza uralensis, Piper nigrum, Rheum cor...

The present research aimed to study the chemical composition and acaricidal activity of Citrus limonum and Piper nigrum essential oils against the cattle tick Rhipicephalus microplus. GC-MS analysis of C. limonum essential oil showed limonene (50.3%), β-pinene (14.4%), and γ-terpinene (11.7%) as the major components; P. nigrum oil was mainly composed of β-caryophyllene (26.2%), σ-ocymene (5.8%)...
