Hot peppers are known for medicinally important capsaicinoids. Bhut Jolokia, Capsicum chinense/Capsicum frutescens, is the hottest pepper in the world. However, its bioactivity and quantity of heat principles are not reported. We have now quantified capsaicin (C) and dihydrocapsaicin (DHC) in Bhut Jolokia and compared it with commonly consumed hot peppers, Jalapeno (Capsicum annuum) and Scotch Bonnet (Capsicum chinense). The concentration of C and DHC in Bhut Jolokia was 5.36%, which is about 338 and 18 times greater than in Scotch Bonnet and Jalapeno, respectively. We have also isolated capsaicin (C) and dihydrocapsaicin (DHC) in pure form and determined lipid peroxidation (LPO) and cyclooxygenase (COX-1 and -2) enzymes inhibitory concentrations. This is the first report of the quantification of C and DHC in Bhut Jolokia, comparison of capsaicinoids content in Bhut Jolokia with Jalapeno and Scotch Bonnet hot peppers and the COX and LPO inhibitory activities of C and DHC.

Abstract Most native Amazonian crops were domesticated in the periphery of the basin. The upper Madeira River basin is an important part of this periphery where several important crops were domesticated and others are suspected to have been domesticated or arrived early. Some of these crops have been reasonably well studied, such as manioc, peanut, peach palm, coca and tobacco, while others are not as well known, such as the hot peppers Capsicum baccatum and C. frutescens, and still others need confirmation, such as cocoyam and annatto. We review the information available for manioc, peach palm, Capsicum, peanut, annatto and cocoyam. The state-of-the-art for Capsicum frutescens, annatto and cocoyam is insufficient to conclude definitively that they were domesticated in the upper Madeira, while all the others have at least one of their origins or centers of diversity in the upper Madeira.

The newest world trends in the scientific research are directed to production of secondary metabolites, their use and application. Capsaicin, the pungent principle of hot peppers is one of the best known natural compound. Nowadays, the research work is directed to the influence of capsaicin on physiological and biochemical processes of humans, animals, and recently plants as a biopesticide. Phytochemical studies of Capsicum annuum L. increase the application of secondary metabolites in pharmacy, food technology and medicine. In this paper, the possibilities of utilization of Capsicum annuum ssp. microcarpum L. for extracting capsaicin and its use as a biopesticide against the green peach aphid Myzus persicae Sulz. in pepper culture are sublimed. The content of capsaicin was evaluated spectrophotometrically, and the ability of capsaicin for acting as biopesticide was calculated according to Abbott. Results showed that oleoresin from Capsicum annuum ssp. microcarpum L. and its dilution 1:20 are the most efficient as biopesticide. From these results we can say that this kind of peppers can be used as a raw material for extraction of capsaicin, because of its high concentration and efficiency.

Resistance of the Hungarian pepper (Capsicum annuum L.) cultivar "Gre.ygo" to Tohamoviruses has been investigated. All plants of the population of Greygo proved to be resistant to tobacco mosaic and tomato mosaic viruses (TMV, ToMV), both represent the pepper pathotypes Po of Tohamoviruses. Individuals of Greygo, however, were found to be susceptible to pathotypes P12 and P123 of pepper mild mottle virus (PMMV). When inoculated with the XM isolate of dulcamara yellow fleck virus (DYFV, pathotype P1) the population of Greygo segregated in resistant and susceptible plants. These results as well as inoculations of the progenies of three TMV resistant plants clearly showed, that besides the resistance allele Li the cultivar Greygo possesses also an another allele. This allele, provisionally marked by L2g behaves like to the allele L2 characteristic to Capsicum frutescens cv. . Tabasco. Determination of the identity of the allele L2g to the allele L2 needs further genetic and pathological informations. Relations between the Tohamoviruses pathogenic to pepper and the alleles of the resistance gene L are outlined for the discussion.

The Abundance and Diversity of Thrips (Thysanoptera: Thripidae) on Chili (Capsicum annuum L.) and Cayenne (Capsicum frutescens L.) in Bogor. This research aimed to study the abundance and diversity of thrips on chili pepper and cayenne pepper plants. Observation of thrips was conducted on chili pepper and cayenne pepper in fourteen sites in four different locations in Bogor that are: Dramaga, Cibungbulang, Tenjolaya, and Cisarua. Thrips were collected from leaves and flowers from 10 plant samples that had been selected randomly. The thrips were identified and the number of thrips were calculated. The abundance of adults, nymphs, and total of thrips on the flowers of chili pepper was 0.39, 0.01, and 0.40 thrips/flower respectively. Meanwhile, the abundance of adults, nymphs, and total of thrips on the flowers of cayenne pepper was 0.36, 0.02, and 0.38 thrips/flower respectively. The abundance of adults, nymphs, and total of thrips on the leaves of chili pepper was 0.68, 0.12, and 0.81 thrips/twiq respectively. Meanwhile, the abundance of adults, nymphs, and total of thrips on the leaves of cayenne pepper was 0.47, 0.14, and 0.61 thrips/twiq respectively. Four species of thrips were found infesting flowers of chili pepper and cayenne pepper i. e. Thrips parvispinus, T. hawaiiensis, Scirtothrips dorsalis, and Haplothrips gowdeyi.  Species of T. parvispinus, T. hawaiiensis, S. dorsalis belong to suborder of Terebrantia family Thripidae, meanwhile H. gowdeyi belongs to suborder Tubulifera family Phlaeothripidae. T. parvispinus is the most dominant species found infesting flowers and leaves of the chilli pepper and cayenne pepper were 71% and 56 %.

A pesquisa teve como objetivo caracterizar parâmetros físicos de frutos e sementes de espécies e variedades doces e picantes de pimentas produzidas na região do Cariri Ocidental paraibano. Foram selecionados frutos de espécies e variedades doces e picantes de pimentas: pimenta-jalapenho (Capsicum annuum var. annuum L.), pimentão (Capsicum annuum L.), chapeu de bispo (Capsicum baccatum L. var. pendulum (Willd.) Eshbaugh), dedo de moça (Capsicum baccatum L. var. umbilicatum (Vell.) Hunz. & Barboza), dulce larga (Capsicum frutescens L.). As plantas foram produzidas no viveiro de mudas do Laboratório de Ecologia e Botânica pertencente ao Centro de Desenvolvimento Sustentável do Semiárido da Universidade Federal de Campina Grande (7o 39' 34,84'' S e 36o 53' 35,96'' W; 538 m de altitude). Foram coletados todos os frutos das plantas após três meses do plantio, que foram analisados quanto ao comprimento longitudinal, diâmetro transversal, massa fresca dos frutos e quantidade de sementes por fruto. Utilizou-se balança analítica com precisão de 0,001 g e paquímetro digital com precisão de 0,01 mm. Os dados foram analisados em Planilha Eletrônica Excel 2013 da Microsoft. O número de sementes por fruto dentro da mesma espécie ou variedade mostrou alta variabilidade, mesmo quando relacionado ao tamanho do fruto. Quanto à massa fresca dos frutos, os maiores valores foram registrados para o pimentão, dulce larga e chapéu de bispo, que produziram também o maior quantitativo de sementes. De modo geral, os dados obtidos contribuíram com informações básicas para a caracterização de frutos e sementes dos diferentes tipos de pimentas estudadas, se constituindo num importante indicador da sua produtividade e desenvolvimento.
