Members of the botanical family Piperaceae were among the first cultivated plants1. Black pepper (Piper nigrum) and long pepper (Piper longum) are the best known species in this family and are probably among the most recognized spices in the world. Black pepper alone accounts for about 35% of the world’s total spice trade. In addition, black pepper and long pepper have been used medicinally for...

Background: Black pepper (Piper nigrum) is mainly cultivated in tropical areas such as South India. It is known as a popular spice in all over the world. Although some studies have been carried out to determine the ingredients of black pepper Essential Oil (EO) cultivated in various regions of the world, but there is little data about some physicochemical characteristics of EO of black pepper c...

Two experiments were conducted to study the effects of red pepper (Capsicum frutescens) powder or red pepper pigment on the performance and egg yolk color of laying hens. In Exp. 1, 210, thirty-wk old, Hy-line Brown laying hens were fed one of seven diets containing 0.3, 0.6, 1.2, 2.0, 4.8 or 9.6 ppm red pepper pigment or 0.3 ppm carophyll red. Each diet was fed to three replicate batteries of ...

ABSTRACT- The production of greenhouse sweet pepper is increasing because of the consumer demand for sweet pepper year around. In this study, physiological characteristics of sweet pepper were evaluated in a greenhouse under different levels of arbascular mycorrhizal fungus, Glomus intraradices, (AMF) and various levels of amino acid (AA). Treatments included no AMF as a control (AMF1), 1000 sp...

The purpose of the present study was to investigate the effect of ethanol extracts from red pepper seeds on the antioxidative defense system and oxidative stress in rats fed a high fat . high cholesterol diet. Rats were divided into four experimental groups which were composed of high fat . high cholesterol diet group (HF), high fat . high cholesterol diet with 0.1% ethanol extracts from red pe...

Pesticides are widely used in Thailand, and can lead to serious acute and chronic health effects. To understand the determinants of pesticide exposure, such as farmers’ behaviors, is important in the effort to reduce exposure effectively. In this study, a standardized questionnaire was designed and used in order to collect information on use and safety behavior related to pesticide in chilli-gr...

Profenofos (Selecron 72% EC), was sprayed on field-grown pepper and eggplant at the recommended rate of 1.28 kg a,i/ha. Fruit samples were collected at 1 h to 14 days after application and analysed to determine the content and dissipation rate of profenofos. The effect of different washing solutions and some household processing on the removal of such residues from treated vegetables were also ...

in this study, extracts and essential oils of black and red pepper and thyme were tested for antibacterial activity against escherichia coli o157:h7 andstaphylococcus aureus. black and red pepper and thyme were provided from iranian agricultural researches center. 2 g of each plant powder was added to 10 cc ethanol 96°. after 24 h, the crude extract was separated as an alcoholic extract and con...

Pepper pericarp microbiota plays an important role in the pepper peeling process for the production of white pepper. We collected pepper samples at different peeling time points from Hainan Province, China, and used a metagenomic approach to identify changes in the pericarp microbiota based on functional gene analysis. UniFrac distance-based principal coordinates analysis revealed significant c...

Due to its high sensitivity and reproducibility, quantitative real-time PCR (qPCR) is practiced as a useful research tool for targeted gene expression analysis. For qPCR operations, the normalization with suitable reference genes (RGs) is a crucial step that eventually determines the reliability of the obtained results. Although pepper is considered an ideal model plant for the study of non-cli...
