“…Due to the diversity presented by genotypes and their great adaptability to different environments, this species is an important phytogenetic resource for pepper crops' breeding programs [21]. Differences due to genetic diversity of genotypes can provide high phenotypic plasticity and variation of morphological traits [22].…”

Piquin pepper (Capsicum annuum var. glabriusculum) is an important species that supports the economy of rural households; it is part of Mexican gastronomy and it is a highly valuable phytogenetic resource. There has been recent interest in domesticating and exploiting piquin pepper commercially, which has been limited until now due to the low germination rate, and this work had the purpose of promoting germination and determining the physiological capacity of genotypes. Ten piquin pepper genotypes from different geographical origins in Mexico were submitted to 11 pre-germination treatments. A completely randomized experimental design was carried out with arrangement in split-plot. The large plot had the treatments and the small plot had the genotypes. The results showed differences (p < 0.01) among treatments, genotypes, and treatment-genotype interaction. On one hand, treatments gibberellic acid (GA) and mechanical scarification + gibberellic acid (MSGA) increased the physiological potential of genotypes, reaching the highest values of germination speed (GS), germination index (IG) and germination percentage (GP); as well as the lowest values of dead seeds (DS) and hard Seeds (HS). In turn, the genotypes that presented the same condition were G8, G7, and G10. Regarding the interaction, each variable had a different condition. In conclusion, we can increase the physiological potential and solve the dormancy of piquin pepper seed by applying gibberellic acid. Likewise, the best genotypes were G8 and G10.

“…The development of cultivars rich in bioactive compounds has been cited as one of the main objectives of breeding programs (Lannes et al, 2007;Wahyuni et al, 2011). Therefore, the characterization of available germplasm is essential to increase conservation of genetic diversity and support breeding efforts (Hayano-Kanashiro et al, 2016). Brazilian germplasm collections conserve many accessions of Capsicum peppers, including landraces selected by farmers for several generations.…”

This report aims to characterize the bioactive content of pepper (Capsicum L., Solanaceae) accessions from a Brazilian germplasm collection. Peppers are currently a major vegetable crop worldwide, with 31 Tg produced in 2013, according to FAO. Seventy‐two accessions of Capsicum annuum L., C. baccatum L., C. chinense Jacq., and C. frutescens L. were evaluated and high variability was observed in soluble solids, pH, acidity, fruit color, total phenolic content, total carotenoid content, antioxidant potential, and capsaicinoid content. Accessions P119, P302, and P189 had the highest phenolic compound contents, which ranged from 225.16 to 243.47 mg gallic acid equivalent 100 g−1. The highest antioxidant potential observed ranged from 2.71 to 3.03 mmol Trolox equivalent 100 mg −1 in accessions P287, P50, and P25. Maximum carotenoid content was seen in accessions P269, P280, and P179, which contained between 53.42 and 54.11 mg β‐carotene equivalent 100 g−1. Capsaicinoid content was highest in accessions P120, P246, and P236 and ranged from 6132.00 to 19,543.70 mg 100 g−1. Capsaicin and dihydrocapsaicin represented, on average, 79% of the total capasaicinoid content. No one accession contained high levels of multiple bioactive compounds.

“…75,77 In addition to piperine, other less pungent alkaloids such as piperlonguminine, piperyline and piperettine can be found in Piper genus. 36,79 Regarding the pungency, Piper nigrum has a small concentration of its major pungent compound when compared to Zingiber and Capsicum. It can be faced as an advantage, in a toxicological perspective.…”

Civilian defense devices are physical and chemical artefacts used to incapacitate an aggressor without causing death or injury. As city violence increases, safety feelings became worst and a growing commercial demand for these materials supply faces technologically challenges not only to riot control but also to self-protection. Controversies on the use of these devices have been discussed, especially on their toxicity when synthetic chemical agents are used. Natural metabolites are a less explored alternative to meet this demand. They have the capacity to generate a temporary disabling effect due to their pungency. Those metabolites, which include capsaicinoids, gingerols and piperine, can be used as deterrent agents in civilian defense devices due to their low toxicity to humans. Although they are a viable alternative, there are few studies focused on their quality control, efficiency and toxicity. This review aimed to present relevant aspects about the development and use of natural products as deterrent agents in self-defense devices against aggressors and animals, and as non-lethal weapons for riot control in order to help the scientific development of this type of bioproduct. was a member of the CAPES and Brazilian pharmacopoeia committees and has published 143 articles in specialized magazines, 13 patents and 38 book chapters, with 50 thesis and dissertations supervised.
